AC MAGNETIC CONTACTORS

CLASS 8502

General Information

Class 8502 Type S magnetic contactors are used

to switch heating loads, capacitors, transformers,

and electric motors where overload protection is

separately provided. Class 8502 contactors are

available in NEMA Sizes 00-7. Type S contactors

are designed for operation at 600 Volts, AC 50-60

Hertz.

Holding Circuit Contact

A normally open holding circuit contact for three

wire control is provided on all contactors as

standard. Sizes 00-2 contactors use a Class 9999

SX11 auxiliary contact as the holding circuit

contact. Sizes 3-7 contactors use a Class 9999

SX6 auxiliary contact as the holding circuit

contact. See Class 9999 for the holding circuit

contact electrical ratings. On Size 00-1 single

phase contactors, a power pole is used as the

holding circuit contact and therefore has the same

rating as the power contacts.

Enclosures

Class 8502 magnetic contactors are available in

the following enclosures:

• NEMA Type 1 General Purpose

• NEMA Type 4 & 4X Watertight and Dusttight

Stainless Steel

Types SB-SD with Auxiliary Load Terminals – Class 8536

3-Pole Polyphase — Three Thermal Units Required

It is sometimes desirable to use the capacitors in motor branch circuits to improve power factor. The Size

0-2 Type SB-SD starters listed included three auxiliary terminals to allow easy connection of power

factor correction capacitors. When capacitors are connected using these terminals, no adjustment on

the selection of thermal units is necessary.

These terminals are also available as a kit Class 9999 Type PFL for Type S NEMA Size 0, 1 and 2

Starters with Motor Logic overload relays. These terminals are available for connection of power factor

(PF) correction capacitors. These kits are sold separately and are not factory installed.

Tables and footnotes are taken from NEMA Standards.

jRatings shown are for applications requiring repeated interruptions of stalled motor current or repeated closing of high transient currents encountered in rapid motor reversal, involving more

than ﬁve openings or closings per minute and more than ten in a ten-minute period, such as plug-stop, plug-reverse or jogging duty. Ratings apply to single speed and multi-speed

controllers.

tPer NEMA Standards paragraph ICS 2-321.20, the service-limit current represents the maximum ms current, in amperes, which the controller may be expected to carry for protracted periods

in normal service. At service-limit current ratings, temperature rises may exceed those obtained by testing the controller at its continuous current rating. The ultimate trip current of over-

current (overload) relays or other motor protective devices shall not exceed the service-limit current ratings of the controller.

aFLUORESCENT LAMP LOADS – 300 VOLTS AND LESS – The characteristics of ﬂuorescent lamps are such that it is not necessary to derate Class 8502 contactors below their normal

continuous current rating. Class 8903 contactors may also be used with ﬂuorescent lamp loads. For controlling tungsten and infrared lamp loads, and resistance heating loads, Class 8903

ac lighting contactors are recommended. These contactors are speciﬁcally designed for such loads and are applied at their full rating as listed in the Class 8903 Section.

uRatings apply to contactors which are employed to switch the load at the utilization voltage of the heat producing element with a duty which requires continuous operation of not more than

ﬁve openings per minute. Class 8903 Types L and S lighting contactors are rated for resistance heating loads.

kWhen discharged, a capacitor has essentially zero impedance. For repetitive switching by contactor, sufﬁcient impedance should be connected in series to limit inrush current to not more

than 6 times the contactor rated continuous current. In many installations, the impedance of connecting conductors may be sufﬁcient for this purpose. When switching to connect additional

banks, the banks already on the line may be charged and can supply additional available short-circuit current which should be considered when selecting the impedance to limit the current.

The ratings for capacitor switching above assume the following maximum available fault currents: NEMA Size 2-3: 5,000 A RMS Sym.; NEMA Size 4-5: 10,000 A RMS Sym.; NEMA Size

6-7: 18,000 A RMS Sym. If available fault current is greater than these values, connect sufﬁcient impedance in series as noted in the previous paragraph.

fSee Page 16 regarding operation rates for Size 6 & 7.

The motor ratings in the above table are NEMA standard ratings and apply only when the code letter of the motor is the same as or occurs earlier in the alphabet than is shown in

the table below. Motors having code letters occurring later in the alphabet may require a larger controller. Consult local Square D ﬁeld ofﬁce.

Size 6 Type SH and Size 7 Type SJ Contactors

and Starters

Size 6 Type SH and Size 7 Type SJ contactors and

starters have a DC coil operated by a solid state

rectiﬁer circuit mounted on the device and

powered from an ac source. The Size 6 and 7 are

equipped as standard with a fused control circuit

transformer (Form F4T) rated 240/480-120 volts

60 hertz, 220/440-110 volts 50 hertz. The purpose

of this transformer is to provide an isolated 120

volts 60 hertz, 110 volts 50 hertz, supply for the

control circuit. Size 6 and 7 devices may be

ordered for other system voltages by specifying

the voltage and frequency desired.

Operation Rates

Continuous operation rate: 3 operations/minute

maximum. Jogging or Plugging Duty: 15

operations/minute – 3 minutes maximum.

Field conversion for other system voltages is

accomplished by one of the following methods,

NOT BY THE USUAL PRACTICE OF CHANGING

THE COIL:

1. If the factory wiring is indicated as being for

480 volts 60 hertz, 440 volts 50 hertz,

conversion to 240 volts 60 hertz, 220 volts 50

hertz, can be accomplished by reconnecting

the control transformer as illustrated on

instruction sheet supplied with the controller.

This is the same method that would be used

on Class 9070 control circuit transformers.

Conversion to any other voltage requires

replacement of the control transformer. For

other system voltages: i.e. 208, 277, 380, 600

volts, a new transformer with single voltage

primary must be selected from table at right.

Control transformer connections are

illustrated on the instruction sheet supplied

with the controller.

2. If the factory wiring is indicated as being for

any voltage other than 480 volts 60 hertz, 440

volts 50 hertz, conversion to any other voltage

requires replacement of the control

transformer. Refer to table at right.

3. The standard transformer supplied may be

used to power a maximum of ﬁve Class 9001

Type K illuminated operators powered with

transformer type light modules. When extra

capacity to power control relays or other

inductive loads is required, a second

transformer must be added. Extra capacity

can be purchased as Form F4T with additions

in 100 VA increments.

4. Standard controllers are wired for common

control and are not convertible for operation of

the control circuit from a separate source of

supply voltage. Controllers designated Form S

have special wiring designed for separate

control. They are furnished with an isolating

transformer, usually having a 120 volt primary

and 120 volt secondary, that must not be

bypassed. Form S controllers are not

convertible for operation on common control.

The tables below give the replacement

transformers for Type S Sizes 6 and 7 contactors

and starters. To change voltages on these

devices, coils are not changed, instead

transformers with the desired voltage are

changed.

Auxiliary Contacts

A N.O. holding circuit contact and a N.C. auxiliary

contact are provided as standard. The holding

circuit contact may or may not be required for

either 3-wire or 2-wire control. Size 6 and 7

devices have an additional N.C. auxiliary contact

which is wired in the coil control circuit. DO NOT

USE THIS N.C. CONTACT FOR ANY OTHER

PURPOSE.

General Information

Class 8502 Type W non-reversing vacuum

contactors are a new addition to the Square D line

of contactors. These contactors are used to switch

capacitors, transformers and electric motors

where overload protection is separately provided.

Type W vacuum contactors are designed for

operation at 600 Volts, 50/60 Hertz.

By design, these contactors are well suited to

heavy-duty applications in harsh environments.

The power contacts are sealed in ceramic tubes,

called vacuum interrupters or vacuum bottles,

where the air has been evacuated. Arc quenchers

are not required because any arc formed between

opening contacts is not sustained due to the

presence of the vacuum. The arc is extinguished

when the current crosses zero after the contacts

are opened, therefore the arc typically does not

survive more than one half cycle. There is one

vacuum interrupter or bottle per pole, therefore a

three pole contactor has three vacuum

interrupters or bottles. The power contacts are not

affected by ambient conditions or contamination.

This provides for long life and reliable operation in

harsh applications.

Altitude

The vacuum contactor is designed to tolerate

normal barometric pressure variances up to 6600

feet above sea level. If the contactor is to be used

above 6600 feet above sea level, please consult

the factory.

Termination Means

The Size 4 vacuum contactor is supplied with line

and load side lugst. The Size 5 and 6 vacuum

contactors are supplied without line and load side

lugs. Class 9999 Type LUW5 and LUW6 lug kits

are available for the Size 5 and 6 contactors.

These kits include six lugs and the necessary

mounting hardware.

Auxiliary Contacts

An auxiliary contact block, Class 9999 Type

WX11, with one normally-open contact and

normally-closed contact is used with the Size 4, 5

and 6 vacuum contactors.

Auxiliary Contact Units

Auxiliary contact units may be added in the ﬁeld.

the table below shows the maximum number of

units that may be added to a given size contactor

(in addition to the coil auxiliary contact).

GENERAL INFORMATION

Class 8702 Type W reversing vacuum contactors

are a new addition to the Square D line of

contactors. These reversing contactors are used

to switch capacitors, transformers and electric

motors where overload protection is separately

provided. Type W reversing vacuum contactors

are designed for operation at 600 Volts, 50/60

Hertz.

By design, these contactors are well suited to

heavy-duty applications in harsh environments.

The power contacts are sealed in ceramic tubes,

called vacuum interrupters or vacuum bottles,

where the air has been evacuated. Arc quenchers

are not required because any arc formed between

opening contacts is not sustained due to the

presence of the vacuum. The arc is extinguished

when the current crosses zero after the contacts

are opened, therefore the arc typically does not

survive more than one half cycle. There is one

vacuum interrupter or bottle per pole, therefore a

three pole contactor has three vacuum

interrupters or bottles. The power contacts are not

affected by ambient conditions or contamination.

This provides for long life and reliable operation in

harsh applications.

Altitude

The reversing vacuum contactor is designed to

tolerate normal barometric pressure variances up

to 6600 feet above sea level. If the contactor is to

be used above 6600 feet above sea level, please

consult the factory.

Termination Means

The Size 4 reversing vacuum contactor is

supplied with line and load side lugs. The Size 5

and 6 reversing vacuum contactors are supplied

without line and load side lugs. Class 9999 Type

LUW5 and LUW6 lug kits are available for the Size

5 and 6 contactors. These kits include six lugs and

the necessary mounting hardware.

Auxiliary Contacts

An auxiliary contact block, Class 9999 Type

WX11, with one normally-open contact and

normally-closed contact is used with Size 4, 5 and

6 vacuum contactors.

Multispeed motors are available in two basic versions:

• Consequent pole

• Separate winding

A separate winding motor has a winding for each speed while a consequent

pole motor has a winding for every two speeds (three speed motors have two

windings). The motor connections (and thus the types of controllers) for two

speed starters are exempliﬁed by the schematic diagrams shown to the left.

Note that consequent pole two speed controllers involve a 5-pole and a

3-pole starter while separate winding controllers have two 3-pole starters.

Separate winding motors are usually chosen when ﬂexibility is important,

since the speeds of a consequent pole motor are usually limited to a 2/1 ratio;

a broad range of speeds can be obtained on a separate winding motor.

Both consequent pole and separate winding motors are available in three types:

• Constant horsepower

• Constant torque

• Variable torque

Typical applications for these different types of motors are shown below.

NOTE: For detailed information involving the technical aspects of ﬂexibility of

the starters used in the multispeed controllers, see Classes 8702, 8736 and

8810 application data.

Typical Applications

Constant H.P.

• Spindles

• Cutting Tools

— Lathes

—Saws

Constant Torque

• Conveyors

• Mills

• Dough Mixers

• Reciprocating Pumps

Variable Torque

• Fans

• Centrifugal Pumps

Speed Selection

The speed of a squirrel cage motor is directly proportional to the power

supply frequency and inversely proportional to the number of poles in the

stator winding. With the frequency constant, motor speed is determined by

the number of poles.

(RPM) Speed = (120) (Frequency)

No. of Poles

Horsepower = T x S Where:

ADDITIONAL FEATURES

Special Relays for Non-Reversing and Reversing Multispeed Starters

General

Standard starters are not equipped with any special relays to require starting

at lowest speed, progressive acceleration or deceleration through each

speed, etc. However, when the type of motor or characteristics of the load

involved make certain starting or control sequences necessary, four types of

relays/timers are available to accomplish the required function.

Form R1 Compelling Relay

This relay makes it necessary for the motor to be started at low speed before

any higher speed can be selected. Pressing any push button except the low

speed will not start the motor. This arrangement insures that the motor will

always start the load at low speed. The stop button must be pressed before

it is possible to change from a higher to a lower speed.

Form R2 Accelerating Relay/Timer

When the starter is equipped with Form R2 accelerating relays, the ultimate

speed is determined by the button which is pressed, but the starter will start

the motor at low speed and then automatically accelerate it through

successive steps until the selected speed is reached. Deﬁnite time intervals

must elapse between each speed change. Individual timing relays are

provided for each interval, and all are adjustable. The stop button must be

pressed before it is possible to change from a higher to a lower speed.

Form R3 Decelerating Relay/Timer

This is similar in action to Form R2 accelerating relays, except that they

function to prevent immediate transfer from a higher to a lower speed. A

deﬁnite time interval, preset on the timer, must elapse between each speed

change.

Form R10 Antiplugging Relays/Timers

If it is necessary to have an imposed time delay when transferring from the

forward to the reverse direction or reverse to forward, then Form R10 should

be included in the form designation of the reversing multispeed starters.

This provides up to a 60 second delay in the transfer of the direction of the

motor, and can help prevent damage which could result from plugging.

Line voltage type, ac two speed starters are designed to control reconnectable squirrel cage motors to

operate at two different constant speeds, depending upon their construction. The use of an automatic

starter and proper control station permits greater operating efﬁciency and offers protection to both motor

and machine against improper sequencing or too rapid speed change. Protection against motor

overload in each speed is provided by an overload relay block which accepts three (3) thermal units.

380 Volts, 50 Hertz – above type numbers will

apply to starters for 380 volt, 50 hertz but the

selection by NEMA size must be based on the

horsepower ratings in the following table:

Thermal Units

Thermal units should be ordered separately. See

Thermal Unit Selection Index. Do not use

horsepower rating(s) for thermal unit

selection. All three phase two speed magnetic

starters require six (6) thermal units, three per

speed. Use nameplate FLC’s (Full Load

Currents) from motor nameplate.

Vertically Arranged, Open Type, Two Speed Starters

Vertically arranged starters are used where width limitations prevent the use of the conventional

horizontally arranged device. Such starters may be used to advantage in threaded NEMA Type 7

explosion-proof enclosures, and in multi-motor panels in which other equipment within the enclosure

used limits the available width.

These starters have all the features of the standard horizontally arranged devices, but the two

contactors are in a vertical arrangement. These starters are offered in open type construction only.

Thermal Units

Thermal units should be ordered separately. For selection of thermal units, refer to the Catalog Thermal

Unit Selection Index, Digest or Bulletin SM-416, entitled “Application and Selection of Overload Relays.”

Do not use horsepower rating(s) for thermal unit selection. All three phase two speed magnetic starters

require six (6) thermal units, three per speed. Use nameplate FLC’s (Full Load Currents) from motor

nameplate.

Special Arrangements with Three Devices

Three Type S Contactors can be mechanically

interlocked so that only one contactor can be

energized at any one time. The mechanical

interlock, pictured in Figure 2, is an interference

(non-jamming) type locking at the beginning of the

stroke of any contactor.

Factory assembled units are listed in the table

below. Figures 1 and 2 show factory assembled

and wired devices. All contactors are both

electrically and mechanically interlocked. The

class and type numbers listed only cover the

contactor and/or starter mounting arrangement,

NEMA size of the devices, and the number of

poles. A power and control wiring diagram must

accompany each order. Additional electrical

interlocks are available factory (or ﬁeld) installed

in the locations shown in Figure No. 2 and Table

No. 2, Page 52. 8810 starters are supplied with

melting alloy type thermal overload relays.

For customer assembled units, the basic

mechanical interlock and base assembly can be

purchased separately. Standard Class 8502

contactors and Class 8536 starters are used in

the locations and pole arrangement shown. If

Class 8536 starters are used, it is necessary to

mount a Class 9999 Type SO bracket below the

overload block to give the block support.

For electrically interlocking customer assembled

units a Class 9999 Type SX-12, normally closed

internal interlock and/or a Class 9999 Type SX-7,

normally closed external interlock can be used.

Ordering Information Required

1. Order complete factory assembled devices by

class and type number from table above.

2. Supply wiring diagram for power and control

connections as catalog number only covers

general contactor and starter mounting

arrangement.

3. Voltage and frequency of contactor coils.

4. Select additional factory assembled electrical

interlocks from table on Page 47 specifying

interlock position letter and whether interlock

is N.O. or N.C.

5. Example of ordering information required on

factory assembled devices:

(a) Class 8810 Type SCO-45

(b) Wired per diagram

(which must accompany order)

(d) Additional electrical interlocks:

C — N.O., E — N.C., and J — N.O.

6. For customer assembly of three mechanically

interlocked devices, order the mechanical

interlock and overload relay mounting

brackets by class and type numbers.

Thermal Units

Thermal units should be ordered separately. For

selection of thermal units, refer to the Catalog

Thermal Unit Selection Index R Digest. Use the

motor nameplate FLC’s (Full Load Currents) to

select thermal units.

AC Two Speed Magnetic Starters

Line Voltage — with Melting Alloy Overload Relays or Solid State Overload Relays – Class 8810

46 5/98

Class 881 and 8812 line voltage starters are designed to control 3 and 4 speed motors, respectively.

The use of an automatic starter and proper control station permits greater efﬁciency. The addition of

compelling relays to a starter gives protection to both the motor and the machine against an improper

sequence or a too rapid change in speed. The motor is protected against excessive operating currents

by overload relay blocks (one for each motor speed) each of which accepts three (3) thermal units. While

the starters listed are for use with consequent pole motors only, separate winding motor starters are

also available upon request.

Thermal Units

Thermal units should be ordered separately. For selection of thermal units, refer to the Catalog Thermal

Unit Selection Index R Digest. All starters require the use of three (3) thermal units for each speed of

the motor. Do not use the horsepower rating(s) for selection. Use nameplate FLC’s (Full Load Currents)

from motor nameplate.

MECHANICAL INTERLOCK

General

Type S contactors or starters can be mechanically

interlocked so that only one device will be

energized at a time. The mechanical interlock is

an interference (non-jamming) type, locking at the

beginning of the stroke of any starter or contactor.

Overload Relay Mounting Bracket

Mechanical interlock Types SM-1 through SM-10

for Sizes 00-2 devices use overload relay

mounting brackets to support the overload relay

portion of the starter.

Type S Sizes 00, 0, 1 and 2

The mechanical interlock is mounted on the

underside of the reversing baseplate. Two pins

extend from the mechanical interlock through

openings in the baseplate and engage the contact

carrier of each contactor. Two styles of

mechanical interlocks are used: one version for

three pole contactors, a different version for four

or ﬁve pole contactors. When adding a power

pole to an existing three pole reversing

contactor, a new mechanical interlock must

also be installed.

Three unit mechanically interlocked contactors

and/or starters are also available for various

combinations of Sizes 0, 1 and 2.

Type S Sizes 3, 4, 5 and 6

The mechanical interlock is separate from the

mounting pan on Sizes 3-6. Cams on the

mechanical interlocks are operated by the contact

carrier of each contactor. The mechanical

interlock is attached to the underside of the two

contactors on Sizes 3 and 4; directly to the

mounting pan on sizes 5 and 6. Size 5 and 6

mechanical interlocks are sold only as a factory

assembly with the 8810 starter.

The mechanical interlock utilizes a special

baseplate and bracket that connects between the

armatures. This is sold only as a factory assembly

with the 8810 starter.

Mechanical Interlock for Two Contactors

Kit Description – The following kits consist of the mechanical interlock and base assembly for

interlocking 2-5 pole contactors. Mechanical interlocks for horizontal and vertical mounting are

listed for various pole arrangements.
