Control Centers Introduction Product Description Product Description Introduction Motor control centers (MCCs) provide the most suitable method for grouping electrical motor control, automation, and power distribution in a compact and economical package. Motor control centers consist of totally enclosed, dead front, free-standing structures bolted together. These sections support and house control units, a common bus bar for distributing power to the control units, and a network of wire trough and conductor entrance areas for accommodating incoming and outgoing load and control wires. The control units consist of components such as combination motor starters, branch feeder devices, AC drives, soft starts, or lighting panelboards. Each unit is mounted in an individual, isolated compartment having its own door. Standard MCC dimensions are 20 in. wide (including a 4 in. vertical wireway trough) by 90 in. high (add 1.5 in. base channel and a 3 in. removable top lifting channel) by 15 or 20 in. deep. Larger sections are often required for mounting larger equipment or for providing space for customer-mounted devices. Two package styles are available: standard and industrial. These Model 6 feature packages allow you to custom design the MCC to fit your specific requirements. The standard package lets you tailor the MCC by selecting only those options that you need for an individual project, guaranteeing the optimal cost/value balance. The industrial package includes options most often requested and specified by industrial customers. Offering the options as part of a package reduces the possibility of leaving out common industrial features. See the following table for a comparison of the two packages. Option Standard Package Industrial Package Structure Features Vertical ground bus material Steel Copper Horizontal bus material Tin-plated aluminum1 Tin-plated copper Fishtape barriers Optional Included Unit Features Interior color Gray White Nameplates Optional Included X1 and X2 wired to terminal blocks Optional Included 1 Exceptions: 1600–2500 A are tin plated copper. All features of the industrial package can be added individually to the standard version. 7 © 1997–2009 Schneider Electric All Rights Reserved 07/2009 Model 6 Motor Control Centers Product Description Features Features • Horizontal power bus is located at the top of the structure for easy installation, inspection, and maintenance without the need to remove units. • Non-conductive, two-piece, sliding, horizontal bus barrier provides convenient access for splicing and maintenance without the need to remove the panels. • Captive, four-bolt, horizontal splice bars with self-contained nuts and hardware make installation easy and reduce the possibility of splice bar loss. • A full-depth vertical wireway maximizes the wire pulling area. The Model 6 MCC has the largest vertical wireway in the industry. • Vertical bus barriers and wireway openings, when supplied, are built in 3 in. increments. This feature allows more mounting flexibility for the units and reduces wasted space in the enclosure. • Vertical ground bus is located in each section. This bus mates with ground stabs on the rear of each plug-on unit to create a positive ground connection, with first make/last break operation. • Frame is constructed with 12-gauge steel, and features welded corner channels for exceptional structural rigidity. • Leveling notches in the base channel provide a means of aligning the section during installation. • Cast metal handle, an industry-exclusive feature, is more rugged than composites, and clearly indicates disconnect status, including a ‘tripped’ circuit breaker, for added safety. • • Quarter-turn fasteners on unit and wireway doors expedite closing and opening. • Each unit is fully compartmentalized, with solid side, back, and bottom plates. This feature allows more mounting space for components and confines any potential faults within the individual unit. • • A hinged, or fold-down, unit bottom plate allows additional space for wiring and maintenance. Sliding Bus Barriers Full Depth Vertical Wireway (Right-Side View) Structural Integrity L-shaped unit door hinge pins are easily removed with a screwdriver for general maintenance. Innovative Shrouded Power Stabs Shrouded power stabs protect stabs against damage during unit maintenance, and provide a self-aligning system for installation of units and connection to the vertical bus. 8 07/2009 © 1997–2009 Schneider Electric All Rights Reserved Model 6 Motor Control Centers Codes and Standards / NEMA/EEMAC Wiring Classes, Enclosure Types Product Description Codes and Standards Model 6 Motor Control Centers are manufactured to National Electrical Manufacturers Association (NEMA) Standard ICS 18-2001 and Electrical Equipment Manufacturers Association of Canada (EEMAC) standards. Model 6 MCCs are also manufactured to Underwriters Laboratories (UL) Standard 845 and bear the “UL Listed” label, where applicable. The “UL Listed” mark is applied to vertical sections and units that are installed within those sections. It should be noted that sections and installed units are independently listed devices. Thus, it is possible to have non-UL Listed units installed in UL Listed vertical sections. ® ® All sections and units listed in this catalog are UL Listed, unless otherwise noted. The Model 6 MCC meets Canadian Standards Association (CSA) specification standards and can carry the CSA label. Certification Model 6 Motor Control Centers are certified by the American Bureau of Shipping (ABS) for use in power distribution, control, and protection of motor and non-motor loads for multiple applications on board ABS Classed Vessels, Offshore Rigs and Platforms, and Marine applications. ABS develops and verifies conformance with standards for design, construction, and operational maintenance of marine-related facilities. Many customers require ABS certification for products used by and for marine facilities. The certification granted by ABS includes classification of use of the motor control center for both Essential and/or Non-Essential Services. NEMA/EEMAC Wiring Classes and Enclosure Types Wiring Classes Class 1—Independent Units Class 1 motor control centers consist of mechanical groupings of combination motor control units, branch feeders, other units, and electrical devices arranged in a convenient assembly. The manufacturer completes wiring between components within each unit. Wiring between units is not required. Class 2—Interconnected Units Class 2 MCCs are the same as Class 1 MCCs with the addition of manufacturer-furnished electrical interlocking and wiring between units as specifically described in the overall control system diagrams supplied by the purchaser. Type A User (field) wiring connects directly to device terminals internal to the unit. Type A wiring is provided only on Class 1 MCCs. Type B User (field) control wiring connects to unit terminal block(s) in or adjacent to each motor control unit. User load (power) wiring for Size 3 or smaller combination motor control units connects as follows: Control Terminal Block Type B-D User load (power) wiring connects directly to the device terminals, which are located immediately adjacent to, and are readily accessible from, the vertical wireway. Type B-T User load (power) wiring connects to factory-wired power terminal blocks located in or adjacent to each unit. User load (power) wiring for Size 4 or larger combination motor control units and branch feeder units connects directly to the unit device terminals. 9 © 1997–2009 Schneider Electric All Rights Reserved 07/2009 Model 6 Motor Control Centers Product Description Enclosure Types / Shipping Weights Type C User (field) control wiring and load wiring on Size 3 or smaller motor control units connects to master terminal blocks mounted at the top or bottom of those vertical sections containing control units. Unit control wiring and load wiring on Size 3 or smaller units are factory-wired from unit-located terminal blocks to the master terminal blocks. User load (power) wiring for Size 4 or larger units connects directly to the device terminals. As an option, user load (power) wiring for all sizes of motor control units may connect directly to the device terminals within the MCC units. See page 85 for load wiring options. Enclosure Types Type 1 Intended for indoor use only. Type 1 enclosures are designed primarily to provide protection against contact with energized equipment inside. They are to be used in locations where normal service conditions exist. Type 1A (Gasketed) Intended to restrict the entrance of dust and falling dirt into Type 1 enclosures. Type 1A enclosures are not dust-tight. Neoprene gasketing is the standard material used. Type 3R Intended for outdoor use only. Type 3R enclosures are designed primarily to provide protection against falling rain and sleet and remain undamaged by the formation of ice on the enclosure. They are not intended to provide protection against conditions such as dust, internal condensation, internal icing, or extreme heat or cold. The Model 6 Type 3R enclosure is built with galvannealed steel, which provides a high level of resistance to corrosion when compared to standard hot or cold rolled steel with the same paint finish. Type 12 Intended for indoor use only. Type 12 enclosures are designed primarily to protect against dust, falling dirt, light splashing, and dripping of non-corrosive liquid. They are not intended to provide protection against conditions such as internal condensation. Shipping Weights One, two, or three vertical sections can be shipped together on a pallet. Larger MCCs are split into shipping blocks of three sections maximum. The following table lists typical approximate shipping weights for a normal mix of MCC equipment. Some sections, based on installed devices and width of the section, may vary from values shown in the table. Approximate MCC Shipping Weights NEMA/EEMAC Enclosure Type 1, 1A, 12 3R Non-Walk-In 1, 1A, 12 3R Non-Walk-In 1 Depth (inches) 1 Section (lbs) 2 Sections (lbs) 3 Sections (lbs) 15 600 1200 1800 151 (27.2 in. overall) 900 1800 2700 20 750 1500 2250 201 (32.2 in. overall) 1050 2100 3150 See the NEMA/EEMAC 3R dimensions drawing on page 108. 10 07/2009 © 1997–2009 Schneider Electric All Rights Reserved Model 6 Motor Control Centers Altitude Ratings / Heat Dissipation Product Description Altitude Ratings The following table lists the MCC derating factors necessary at altitudes of 6,600 ft (2,000 m) and higher.

For solid state reduced voltage starters above 3,300 ft (1,000 m), derate the nominal output current by 2.2% for each additional 330 ft (100 m) up to a maximum of 6,600 ft (2,000 m). Motor Control Center Heat Dissipation The following table lists the approximate heat dissipation of various MCC units. This information is often requested by engineers who are sizing HVAC equipment to cool and ventilate equipment rooms. Values include an estimate of heat dissipated by the MCC Power Bus. To use, add the values for each of the units in the MCC. Values are given in BTUs per hour and watts. The values given are for “typical” applications, and include an adjustment for power bus contribution. Make the following adjustments for special situations: • Add 10–20 percent to the total heat dissipation for MCCs that make extensive use of relays, timers, and other control devices. • • Add 10 percent to the total heat dissipation for MCCs with 1200–1600 A main bus.

In the majority of MCC applications, the system is rated as 480 V, 3-phase, 3-wire. If a neutral wire connection is required, a neutral kit can be supplied (see “3-Phase, 4-Wire Systems” on page 26). Typically, one of three devices is used to connect power to the MCC: main lugs, main circuit breaker, or main fusible switch. One of these devices is connected to the horizontal main bus with cable or hard bus. Cabled or bussed branch devices or cabled starter units (those with an L, M, or P frame circuit breaker disconnect, or 600 A or larger fusible switch disconnect) cannot be installed in the same section as a main device. As with all electrical equipment rated 600 V or less, incoming cables must be rated using the 75 °C temperature ratings tables in the National Electrical Code® (NEC®). The incoming lugs are 194° F (90 °C) lugs, and 194 °F (90 °C) cable can be used. However, the cable must be applied to the 75 °C ratings. All main devices must be top- or bottom-located. Main Lug Compartments Main lug compartments must be specified in the absence of other incoming line provisions. 3-phase, 3-wire main lugs include neutral assembly for cable connection to other units with solid neutrals.

The tie breaker consists of a PowerPact® or Masterpact circuit breaker and hard bus transition network to complete the connection between the power buses from each MCC. The mains of the two MCCs may be on the outside ends or in the middle of the lineup with a tie breaker. The Trip Rating, Frame (Amps), and Breaker Frame of the tie breaker should match those of the main. Neutral bus is not available in the tie breaker, therefore the neutral is not continuous nor switched through the tie. Contact factory for applications requiring continuous or switched neutral. The standard configuration includes a manual throwover of the tie breaker. Automatic throwover systems controlled by a programmable logic controller can be provided for PowerPact P-frame or Masterpact NW circuit breakers in the MCC.

As an option, a neutral lug assembly (Figure 1 in “4-Wire Examples” on page 27) can be provided in the incoming main section to terminate a neutral conductor. Additional lugs can be added for connections to the neutral. When 4-wire loads are present in the MCC, solid neutral bussing (Figure 2 in “4-Wire Examples” on page 27) can be provided in individual sections and connected to provide a continuous neutral bar. A neutral lug termination option must be selected for the incoming main section when selecting solid neutral bus in the MCC. Lugs are not provided when selecting solid neutral bus, but holes are pre-drilled to accommodate user-mounted lugs. As an option, neutral conductors for loads can be connected to the MCC neutral bus via a neutral bus drop located in each vertical wireway for easy access (Figure 2 in “4-Wire Examples” on page 27). A special 12 in. neutral distribution unit (Figure 3 in “4-Wire Examples” on page 27) can be provided to terminate branch device neutral connections in 15 in. deep sections. Such branches should be located close to the main for easier interconnections. A neutral lug termination option must be selected when selecting a neutral distribution unit.

Installation on an ungrounded power distribution system is not recommended. See the figure below for proper transformer feed to the MCC where TVSS units can be applied. • • Must be located as close as possible to the incoming main provision. • TVSS components for installation in MCC-mounted panelboards or on distribution transformer secondaries should use a panel-mounted TVSS component. TVSS units for 4-wire systems must include a solid neutral bus and/or neutral lug termination assembly in the MCC.

Select the TVSS Model based on: a. System voltage (480 Vac, 240 Vac, 208 Vac, or 600 Vac). b. Desired surge current capacity (120 kA, 160 kA, or 240 kA). If a surge current capacity higher than 240 kA is required, more than one TVSS unit can be added to the MCC to bring it to the desired surge current capacity. When adding more than one TVSS unit to an MCC, all units should be mounted in the same section, if possible, and as close as possible to the MCC incoming main unit. c. Type of loads to be protected (branch loads, service entrance applications, or large individual loads). d. If backup redundancy is a requirement, two TVSS units should be added in the same MCC section and in adjacent mounting spaces. 2. Select the TVSS model based on the main power transformer connection (see figure above), desired surge current capacity, and type of loads to be protected. 32 07/2009 © 1997–2009 Schneider Electric All Rights Reserved Model 6 Motor Control Centers Incoming Devices Application and General Information Model IMA TVSS (120 kA Surge Rating) • • For protection of small MCC lineups and non-critical loads 120,000 A per phase surge current capacity Customer Incoming Power Connection to MCC System Voltage Space (Inches) 208 Vac Three phases with or without neutral connected to MCC (3- or 4-wire MCC).

Units are available for three phase, 60 Hz, 208 V, 240 V, 480 V, or 600 V, 3- or 4-wire power systems. The Altistart 48 soft start in MCCs can provide soft starting (reduced voltage) and deceleration along with machine and motor protection of standard NEMA B-Design three-phase squirrel cage asynchronous motors in the following power ranges: 3–200 hp @ 208 V 5–250 hp @ 230 V 10–500 hp @ 460 V 15–600 hp @ 575 V The MCC soft start units integrate the latest technology Altistart 48 soft start from Schneider Electric into a combination starter package for MCCs. MCC soft start units include a shorting contactor, shunt trip input power disconnect, door-mounted keypad, and 120 Vac control circuitry. TeSys® D- and F-Line contactors are standard (NEMA-type contactors are optional). All packages and options are UL 845 Listed for a minimum 65,000 Amp short circuit rating up to 600V (ratings of 100,000 A @ 600 V are available with fuses). All soft starter units with circuit breaker disconnects through 250 A and 800–1200 A frames use PowerPact® thermal magnetic (TM) circuit breakers. All soft starter units with 400–600 A frame disconnects use L-frame thermal-magnetic (TM) circuit breakers. The fusible switch disconnects used on MCC soft start units are automatic molded case switches. Provisions for Class J or L fuses are provided. Fuses are not installed at the factory. All units are UL Listed. Selection The ATS48 controller must be selected on the basis of 3 main criteria: Main voltage supply: Three-phase AC voltage: 208, 240, 480, or 600 V The power and the nominal current (motor FLA) indicated on the motor nameplate The type of application and the operating cycle. The application types are: — Standard duty — Severe duty NOTE: Standard or severe duty applications define the limiting values of the current and the duty cycle ratings. Standard Duty Applications In standard duty applications, the ATS48 controller is designed to provide: Starting at 400% nominal motor current (In) for 23 seconds or at 300% nominal motor current (In) for 46 seconds from a cold state Starting at 300% nominal motor current (In) for 23 seconds or at 400% nominal motor current (In) for 12 seconds with a load factor of 50% and 10 starts per hour or an equivalent thermal cycling The motor thermal protection conforms to Class 10 overload protection. Severe Duty Applications In severe duty applications, the ATS48 controller is designed to provide: Starting at 400% nominal motor current (In) for 48 seconds or at 300% nominal motor current (In) for 90 seconds from a cold state Starting at 400% nominal motor current (In) for 25 seconds with a load factor of 50% and 5 starts per hour or an equivalent thermal cycling The motor thermal protection conforms to Class 20 overload protection. 60 07/2009 © 1997–2009 Schneider Electric All Rights Reserved Model 6 Motor Control Centers Soft Start Units Application and General Information Contact the MCC TAG for additional application information for those applications requiring: 2-speed or delta-wye motors The ATS48 can operate with a 2-speed motor. A motor demagnetizing period must elapse before changing from low speed to high speed in order to avoid antiphase between the line supply and the motor, which would generate very high currents. Motors other than NEMA Design B High efficiency motors Low slip motors Power factor correction capacitors Do not connect power factor correction capacitors to the terminals of a motor controlled by an ATS48 soft start. The power factor capacitors must be controlled and connected to a line side contactor sequenced by the ATS48 at end of starting. Controller oversizing of more than 50% Multi-motor applications Motors may be connected in parallel provided that the power limit of the starter is not exceeded (the sum of the motor currents must not exceed the nominal current of the starter selected, depending on the type of application). Individual thermal protection and local disconnect is required for each motor. Non-standard trip characteristics Modifications not listed in this catalog Horsepower greater than those listed in this catalog Long motor cable lengths Very long motor cables cause voltage drops due to the resistance of the cable. If the voltage drop is significant, it could affect the current consumption and the torque available. This criteria must be taken into account when selecting the motor and the starter. NOTE: Do not use the ATS48 controller upstream of loads other than motors (for example transformers and resistance type loads). See the Altistart 48 catalog #8636CT0201 and data bulletin #8600PD9201 for additional information. 61 © 1997–2009 Schneider Electric All Rights Reserved 07/2009 Model 6 Motor Control Centers Application and General Information Soft Start Units Features Shorting Contactor A shorting contactor is supplied on all units. This allows the motor current to bypass the soft start's thyristors once the soft start has ramped up to full voltage/full speed. The use of a shorting contactor reduces temperature rise within the enclosure during steady state operation and requires less current carrying duty on the thyristors. Torque Control System (TCS) The Altistart 48 uses TCS ramping to accelerate the motor to full voltage. Basing the acceleration ramp on the motor torque rather than current or voltage, as used in traditional soft starts, provides a linear speed ramp independent of the motor loading without tachometer feedback. The TCS ramp is also used for improved control of deceleration and eliminates the need for a special controller to handle water hammer problems. Starting and Stopping Four types of starting are available: TCS soft start—adjustable from 1 to 60 seconds TCS with “boost”—adjustable from 50 to 100% of mains voltage Current limit—adjustable from 150 to 500% of controller rating Voltage ramping Three types of stopping are available: Freewheel or coast to stop TCS soft stop—adjustable from 1 to 60 seconds InTele braking—adjustable from 50 to 100% Protective Features Solid state motor thermal overload protection—programmable from Class 10 through 30 Soft start thermal protection Motor phase loss protection Line supply failure Overcurrent fault Locked rotor fault Line frequency outside limits +/-5% or +/-20% Selectable protection, including: — Phase reversal — Stall and jam — Thermal overload pre-alarm — Current threshold alarm — Underload fault Transient suppression modules on all contactors 62 07/2009 © 1997–2009 Schneider Electric All Rights Reserved Model 6 Motor Control Centers Soft Start Units Application and General Information Monitoring and Indication Door mounted keypad: Displays setup parameters and fault codes.

Additional housing and gasketing provide protection from rain, sleet, and ice. The Type 3R MCC for AC drives and soft starts features louvered and filtered openings on the front doors, along with humidity controls inside the enclosure (see Figure 1). The MCC enclosure is further modified to include fan-forced ventilation while continuing to meet NEMA/EEMAC Type 3R enclosure requirements and the UL 845 MCC standard. Center Ventilated NEMA/EEMAC Type 3R Enclosure D D D Environmental Controls Filtered Ventilation Transformer Power Supply for Environmental Controls Fans Space Heaters Front View of NEMA/EEMAC Type 3R MCC (dashed lines represent units) Side View of NEMA/EEMAC Type 3R MCC Environmental Control The ventilated NEMA/EEMAC Type 3R MCC manages the internal MCC environment to maintain the required temperature and humidity levels for the drive and soft start controls in outside environments from 14 to 104 °F (-10 to 40 °C). The following features are included: Dual Door Fans—Dual door fans force fresh air into the enclosure and move air out of the enclosure. The centrifugal impeller fans use highly reliable ball bearing rotors. A factory-preset thermostat controls the fans, based on the MCCs internal temperature. Door interlock switches turn the fans off when the outer NEMA/EEMAC Type 3R door is opened. Positive Pressure Ventilation—The intake fans, mounted at the lower vents, blow air into the cabinet. This air increases the cabinet's internal air pressure relative to the air pressure outside the cabinet. The “positive” air pressure created inside the cabinet helps force out dirt and contaminants. This positive pressure ventilation method is common practice for industrial atmospheres: it provides a cleaner environment for drive and soft start electronics than one that would be created by exhaust fans mounted at the upper vents. Space Heaters—Space heaters add heat to prevent condensation during cooler periods, overnight, and in winter weather. NOTE: Space heaters do not permit use of the MCC in temperatures below 14 °F (-10 °C). 66 07/2009 © 1997–2009 Schneider Electric All Rights Reserved Model 6 Motor Control Centers NEMA Type 3R Enclosures for AC Drives and Soft Starts Application and General Information Humidity Controls —It is crucial to maintain a level of dryness in or around the electronic controls for drives and soft starts. Condensation must be avoided. The space heaters will supply the MCC with heat when necessary to reduce condensate formation. A factory-preset thermostat and humidistat monitor humidity levels and turn on the space heaters to dry the internal MCC ambient air. Self-Contained Power Supply—The fused control transformer(s) supplied in each MCC line-up provide power for space heaters and fans. There is no need for external power once the main 3-phase power is connected. The power supply is prewired at the factory to fans, space heaters, and environmental controls through protected wiring provisions. Each transformer is able to supply power to three sections and should be mounted at the bottom of the MCC section. Filtered Louvers—Each NEMA/EEMAC Type 3R MCC door contains top and bottom louvers for ventilation. Behind each louver is a coarse rubber filter that helps keep debris from entering the MCC. NOTE: All drives and soft starts include internal thermal protection switches to shut down the drive or soft start unit before damage occurs. Ratings Altivar 71: 1–40 hp, 480 V, or 1–15 hp, 208/230 V NOTE: A maximum of four ATV71 drives are allowed in a single section. Mount drive units starting at the top of the section.

Overload Relays Model 6 motor control center units with Type S starters are available in NEMA/EEMAC Sizes 1 through 6. Type S starters are provided with melting alloy overload relay blocks as standard. Their trip-free construction allows the overload relay to trip even if the reset lever is blocked or held in the reset position. Features such as the trip-to-test and the visible trip indicator minimizes troubleshooting time. With these features and state-of-the-art design, the Model 6 starter unit has earned a solid reputation that no other NEMA/EEMAC starter can equal. Schneider Electric has added the solid state motor overload protection to its existing family of overload relay protection equipment, including melting alloy and bi-metallic devices. Technological migration allows Schneider Electric customers the ability to make the same space “smarter,” while preserving backward compatibility.

Standard feature if reversing or full voltage bypass is chosen.) As an option, MCC soft start units can include an input contactor instead of a shunt trip disconnect to isolate the soft start in case of a fault condition. The input contactor also opens when the motor is not in use. This provides protection from voltage transients when the electronics are most susceptible to damage. Control power is maintained after the input contactor is opened so fault diagnostics are available. Integrated Full Voltage Bypass Starter (requires input isolation contactor) As an option, MCC soft start units can include a full voltage bypass to allow emergency full voltage starting of the motor in case the soft start is unable to be used. This feature includes necessary control and power circuitry to start the motor with full voltage using a bypass enable/disable selector switch. A Class 20 overload relay is provided to protect the motor in the bypass mode. The bypass contactor also acts as a shorting contactor in the soft start mode. Not available with Reversing Capability.

Corrects to the 50th harmonic; reduces harmonics level to meet IEEE 519 at the MCC main incoming power connection. Reduces downtime caused by nuisance thermal tripping of protective devices. Cost effective approach to groups of harmonic loads and as an alternative to multi-pulse drives. Increases electrical network reliability and reduces operating costs. When installed in the MCC, the AccuSine PCS will compensate for harmonic loads within and fed by the MCC. This is an essential function as MCCs continually incorporate more and more solid state components such as AC drives, soft starts, and PLCs, which increase the potential for power quality issues. The Model 6 MCC AccuSine package includes: 50 A or 100 A rated model Accusine PCS for 208–480 V Door-interlocked disconnect and fusing Door-mounted display (HMI) for programming and monitoring Suitable for use in 100 kAIC rated MCCs UL/cUL Listed Rated for NEMA/EEMAC Type 1 or Type 1A (Gasketed) enclosures. Not available for Type 12 or Type 3R enclosures. Two current transformers for installation by contractor at the MCC main incoming cables. Three CTs are supplied when single-phase loads are present. Up to five multiple units can be connected in parallel to increase compensation up to 500 A of harmonic current compensation. Standard MCC bus and enclosure depth allow the active filtering to be retrofitted onto the MCC for future expansion of harmonic compensation.

Unlike passive devices, AccuSine PCS is easy to apply and cannot be overloaded. For proper sizing, contact your local Schneider Electric representative, or visit the Schneider Electric website (www.schneider-electric.us) for downloadable sizing software. To expedite the product selection process, have a single line diagram and/or details of the application including sizes of transformers, non-linear and linear loads, and any existing filters and capacitors.

Schneider Electric supports two popular methods for configuring Model 6 iMCCs to customize your application: • • iMCC-Hardwired I/O: PLC Interwiring iMCC-Network: Network Cabling iMCC- Hardwired I/O: PLC Interwiring offers a hardwired I/O system in the Model 6 MCC that provides basic information and control capabilities. With the I/O mounted in the MCC, the starters are wired to the I/O at the Schneider Electric manufacturing plant and the system is tested prior to shipment. This pre-wired MCC is more cost effective than separately mounting and wiring the automation hardware outside of the MCC. This option can also include an independent network. iMCC Network: A key feature of our iMCC-Network solution is the integration of intelligent devices and device level networks for control and automation that delivers improved performance. Popular network protocols such as CANopen, DeviceNet™, Ethernet, Modbus®, and PROFIBUS communicate directly to every unit of the iMCC for an effective method of connecting centralized control to widely distributed I/O. The network of your choice creates a common thread for a variety of motor control equipment that not only improves control, but also allows for simple and easy installation and operation. Networking allows for easy monitoring of critical data of each motor or load connected to the iMCC, enabling precise process control at all times. With this information, your staff can respond to potential problems proactively. Real-time access to information and records of last faults allows for simplified diagnostics and reduced downtime. Using network control to consolidate all I/O communications significantly reduces the amount of tedious wiring that would normally be required for a hardwired I/O MCC with similar functionality. We design a network cabling solution that is appropriate for your selected communication network. Our industry-leading full-depth wireway effectively separates network cabling from high voltage cabling. Additionally, our standard wireway barrier isolates the communication cabling from the load cabling routed in the vertical wireway. Experience the benefits of an iMCC network: • • • • • • • Remote monitoring capability Reduced downtime and system interwiring Control to every bucket Lower commissioning costs Flexible configuration Cabling system compliant to applicable standards. DeviceNet solution is Open DeviceNet Vendor Association (ODVA) certified. 98 07/2009 © 1997–2009 Schneider Electric All Rights Reserved Model 6 Motor Control Centers Intelligent Motor Control Centers Common Mounting Configurations for Automation Components PLC components are packaged in Schneider Electric MCCs in two distinct configurations: a unit-mount configuration and a full-section configuration.

Because of ever increasing short circuit requirements, Schneider Electric continually pursues higher ratings through new design and testing. Many “buzz” words and terms are used to describe short circuit ratings and how they relate to motor control centers. Here are a few with a description of what they actually mean: Bus Bracing or Withstand Rating This term describes the capacity of the bus network to withstand the mechanical forces generated during a short circuit (fault). Integrated Equipment Rating This term is not clearly defined, especially when applied to motor control centers. While it is often assumed that this term means series connected short circuit ratings or short circuit current ratings, this term can also have other interpretations. Integrated equipment ratings are generally not provided for MCCs. Interrupt Rating This term describes the maximum fault current level that a particular device can interrupt. This type of rating applies only to devices that operate to interrupt a short circuit when it occurs. This term does not apply to power bus or components of the electrical system that do not interrupt current. Different units within the same motor control center may have different interrupt ratings. Further, the interrupt rating does not take into consideration the effect of a main device or the bus withstand rating. Series Connected Short Circuit Current Ratings This term describes short circuit ratings that take into consideration the effect of a main overcurrent protective device located in the motor control center or in upstream equipment. It does not necessarily mean that the main has to open whenever a fault occurs. Many engineers feel that series connected short circuit ratings mean that a system cannot be “coordinated” (coordination refers to a system’s capability of interrupting a fault at the lowest level thereby limiting the amount of equipment shut down as a result of that fault). System coordination should be considered when designing any electrical distribution system and the level of coordination will often dictate the type of equipment used. It is possible to maintain acceptable levels of system coordination while utilizing series short circuit ratings and alternately, avoidance of series connected short circuit ratings will not automatically mean that the system will be fully coordinated. Fault coordination should not be confused with series connected short circuit current ratings. Short Circuit Current Rating This term is Schneider Electric’s “bottom line” in describing the overall short circuit rating of a motor control center. It means that the motor control center will withstand and/or interrupt a fault on an electrical system capable of supplying the specified fault current. To be properly applied, a motor control center must have a short circuit current rating equal to or greater than the specified available fault current. In order to obtain this rating, a motor control center must contain: 1. A main device capable of interrupting the specified fault current, located in the motor control center or in upstream equipment. A short circuit current rating of a motor control center cannot be greater than the interrupt rating of the main device feeding it. or: 2. A bus bracing or withstand rating equal to or greater than the specified fault current. 102 07/2009 © 1997–2009 Schneider Electric All Rights Reserved Model 6 Motor Control Centers Short Circuit Current Ratings Technical Overview and: 3. Units with short circuit current ratings equal to or greater than the specified fault current. All units must either have an interrupt rating greater than or equal to the specified fault current or carry a series connected short circuit rating greater than or equal to this level. UL Listed Short Circuit Current Ratings Underwriters’ Laboratories (UL) has defined test criteria for motor control center short circuit ratings. In general, UL witnesses the testing of “worst case” configurations of motor control center units, structures, and bussing at the short circuit current levels for which the equipment is being rated. In many cases, such as units with circuit breaker disconnects, the same unit must be subjected to those fault levels more than once. To pass, equipment must withstand and/or interrupt the fault in accordance with UL criteria. UL Listed short circuit ratings ensure that different manufacturers are “comparing apples to apples” when describing short circuit current ratings. “Self-Certified” Short Circuit Current Ratings Short circuit current ratings that are obtained through first-party testing and/or engineering evaluation, are certified by the manufacturer, and are not UL Listed are known as “self-certified” ratings. Self-certified short circuit ratings should not necessarily be considered unacceptable. However, caution should be used because the basis for the short circuit ratings may differ from one manufacturer to another.
