trip units with the latest electronic,
digital trip unit technology
•
Ensure safe, reliable operation with
ANSI C37.59 tested kits
•
Improve system protection and
increase productivity by eliminating
nuisance tripping
•
Integrate mixed switchgear with kits
available for Westinghouse, I-T-E
& Allis Chalmers low voltage power
circuit breakers
GE Industrial Systems
GE AKU-2A-50
with MicroVersaTrip PM trip unit upgrade
Now upgrade your low-voltage
power circuit breakers with
electronic trip unit technology
Normal wear and tear of aging electro-mechanical
trip devices on low-voltage power circuit breakers
increases susceptibility to loss of calibration that
can subsequently jeopardize electrical power
system coordination, protection and reliability.
GE has channeled its decades of circuit breaker trip
system experience into the development of the
MicroVersaTrip®Plus and MicroVersaTrip®PM
conversion kits for GE, Westinghouse, I-T-E, and
Allis Chalmers low-voltage power circuit breakers.
ANSI C37.59 design verification tested to ensure safe,
reliable operation, these kits are designed to extend
the life of your mechanically sound breakers and…
• Eliminate costly downtime due to nuisance
tripping
• Improve electrical power system coordination
and protection
• Permit easy upgrades to communicating Power
Management Control Systems (PMCS)
• Provide safe, convenient closed-door local
metering via the optional Remote Display
Standard and optional features
Standard MicroVersaTrip Plus and MicroVersaTrip
PM adjustable trip unit functions include:
• Current setting
• Long time
• Long time delay
• Instantaneous
• Local fault trip indicators
Optional features include:
• Short time
• Short time delay with or without I2t
• Ground fault
• Ground fault delay with or without I2t
• Switchable instantaneous/short time and ground
fault (off) (not UL approved for a listed breaker)
• Full function metering (MicroVersaTrip PM)

MicroVersaTrip Plus conversion kit features
• Superior trip unit accuracy and system protection is achieved by
taking 64 samples per 60 Hz cycle. This provides true RMS sensing
of electrical distribution systems that include AC and DC variable
speed drives, rectifiers, induction heaters and other loads that
contribute to non-sinusoidal (high-harmonic) current wave forms.
• Easy system coordination with maximum flexibility is obtained
using multiple trip setpoints, time-delay bands and ramp time
functions.
• Visual pickup and trip indicators for overload, short circuit and
ground fault, display type of fault,
phase and current magnitude when
applicable
• Predictive and preventative
maintenance decisions are made
easily using the trip operations
counter that stores the total number
of Long time, Short time,
Instantaneous and Ground Fault
trips.
• Continuously self-testing micro-
processor eliminates trip unit
bench-testing
• Non-volatile memory
• High-visibility LCD display
• Cold setup capability and target
viewing from long-life (5-year)
field- replaceable lithium battery – external power not required
• Positive setpoint recognition, values flash until entered and
accepted
• Easy access 5-button keypad with positive action
• Phase selectable ammeter (±2% accuracy)
• Sealable, clear Lexan protective cover over LCD display and
“Enter” key prevents unauthorized access to protective functions
and target reset
• Interchangeable rating plug
• Quick-disconnect trip unit design speeds installation and allows for
easy upgrade to MicroVersaTrip PM units with communications
capability, full-function metering and optional protective relaying
functions

PM conversion kits—
Power management made easy
The enhanced MicroVersaTrip PM trip unit adds power
management system capability – including advanced
metering and protective relaying – to the basic functions of
the MicroVersaTrip Plus. When connected to GE’s Power
Management Control System (PMCS), it gives you the power
to increase productivity and reduce costs while meeting all
your electrical system monitoring needs. You can easily:
• Use standard graphics packages that allow the end user to
view custom one-lines for metering and trending screens
• Analyze energy consumption and power factor trends
to minimize utility demand and PF charges or provide
low-cost allocations
• Collect precise sequences of alarm and event information
to speed diagnosis and minimize downtime
• Use alarm and event logs to assist with preventive
maintenance interval planning
• Analyze system harmonics (with data input from PQM,
EPM 3710, EPM 3720 or EPM 7700 meters)
• Communicate with other devices, including Spectra
Series™ molded case and Power Break™ insulated
case breakers, full-function electronic power meters,
programmable logic controllers, GE Multilin protective
relays and “smart” motor starters
• Utilize GE’s Power Management Control System and its
industry standard Modbus RTU, Ethernet TCP/IP
open protocols
Optional Remote Display
• Provides safe, convenient closed-door access to breaker metering, status
and setup functions
• Available for use with either MicroVersaTrip®Plus or MicroVersaTrip PM
trip units
• Rugged NEMA Type 1 enclosure with LCD display and keypad
• Mounts easily on outside of breaker compartment door
• Sealable, clear Lexan protective cover over display and “Enter” key
prohibits unauthorized trip setting changes
• Connects to breaker trip unit via tough non-flammable, non-toxic 20-pin
plug-in cable for fast installation
• Breaker trip unit operates independently if cable is disconnected
Additional features
• Full-function metering* including
– current (Amps, kAmps)
– voltage (Ph-Ph, Ph-N)
– energy (kWh, MWh, GWh)
– real power (kW, MW)
– total power (kVA, MVA)
– frequency (Hz)
– demand & peak demand (avg. kW, MW)
• Optional protective relaying* functions include
– undervoltage
– overvoltage
– voltage unbalance
– current unbalance
– power reversal
– power direction setup
*Requires potential transformer and
voltage conditioner inputs (not included
in kits – auxiliary panels sold separately)
