INTRODUCTION
The electronic trip control unit described in this publication is a solid state,
microprocessor controlled unit, used in conjunction with a power circuit breaker to
protect power systems. The power circuits being protected are typically 3-phase,
with and without a neutral connection, 50 or 60 Hz with AC RMS voltages between
208 and 600 volts and continuous currents as high as 4200 amps, while ground
currents may not exceed 1200 amps.
The primary function of the electronic trip control unit is the coordination in the
opening of circuit breakers to protect equipment in the event of a fault that
produces short circuit currents of up to 130 KA.
The MPS-C 2000 trip control unit measures current to an accuracy of within 1% of
the cicuit breaker rating.
The Voltage Interface Module (VIM) option measures voltage to an accuracy of
within 1% of the circuit breaker rating, and power to within 2% of the circuit
breaker rating.
The trip unit is completely self-powered, taking the the tripping energy from the
current through the breaker without any auxiliary power supply.
The complete control of the circuit breaker is achieved by a system comprising:
(a) current sensors, (b) an electronic trip control unit, and (c) a magnetic latch trip
device.
The sensors, the electronic trip control device and magnetic latch are mounted
as an integral part of the circuit breaker to provide complete protection for
overcurrent, short circuit and ground faults. Internal diagnostic circuitry is provided
to determine and visually identify the cause of circuit breaker tripping, either as
overload, short circuit or ground fault.

1. FUNCTIONS.
The electronic trip control device provides the following four basic functions:
1.1 Protection Function
Four basic trip elements within the unit perform the protective functions:
Long time, short time, instantaneous and ground.
1.2 Information Function
An indicator (target) and an LCD screen display information for the tripping functions.The indicator shows if
the device has issued a trip command and the LCD can be polled to determine the type of trip. The LCD and
keypad buttons are used to determine the settings of the unit. A red LED indicates self-monitoring functions.
1.3 Test Functions
The unit can be connected to an external test set to check functions and settings.
1.4 Communication Functions
The unit can be connected to switchgear mounted devices which are connected to ABB INCOM Protocol.
2. SETTINGS.
2.1 Range Selection
The range selector provides the primary amperage used as the base for the unit. It is either set for the 1 X or
0.5 X the breaker rating: Default is 1 X.
2.2 Long Time Function
2.2.1 Threshold (pickup)settings- The range of settings is: 0.5 to 1.0 in steps of 0.1. Multipliers are used in
conjunction with sensor rating and the range selector. Multipliers are selected by keypad input and displayed on
the LCD. Default is 1.0.
2.2.2 Trip Time - Time is defined by long time overcurrent curves (graph) and intermediate values between band
limits. Default is MAX.
2.2.3 Reset Time - Real time is counted up if the current exceeds the function threshold and counted down if the
current drops below the function threshold. Real time is set to zero if the current drops below the power supply
threshold.
2.3. Short Time Function
2.3.1 Threshold (pickup) settings - 2 3 4 5 6 7 8 9 10 DISABLED. The settings are multiples of the sensor ratings
and the range selector. Settings are made by the keypad and the LCD display. If the INST function is disabled, the
short time unit cannot be disabled. Default is DISABLED.

IB 6.1.2.8-1B
Page 5 ABB
2.3.2 Trip time - Time is defined by the short time overcurrent curves (graph). I²t function is selectable.
I²t curves are fixed and do not vary with pickup settings. I²t is operational only from 2X to 4X. Trip times with I²t out
are defined as follows: Default is maximum with I²t in.
Maximum = 0.350 - 0.500 sec
Intermediate = 0.20 - 0.320 sec
Minimum = 0.080 - 0.170 sec
2.3.3 Reset time - Real time is counted up if the current exceeds the function threshold and counted down if the
current drops below the function threshold.
2.4 Instantaneous Function
2.4.1 Threshold (pickup) settings - 3 4 5 6 7 8 9 10 11 12 DISABLED. The settings are multiples of the range
selector setting and are made via the keypad and the LCD screen. If the short time unit is disabled, the
instantaneous unit cannot be disabled. Default is 12.
2.4.2 Trip time - There is no intentional delay in the instantaneous function.
2.4.3 The instantaneous unit includes a jumper on the circuit board which eliminates the possibility of instantaneous
and short time being simultaneously disabled.
2.5 Ground Function
2.5.1 Threshold (pickup) settings - These settings are made via the keypad and the LCD screen. This function may
also be disabled. Default is 1200 A.

2.5.2 Trip time - The time is defined by the overcurrent curves (graph). I²t function is selectable. I²t curves are fixed
and do not vary with pickup settings. If the I²t function is out, the trip times are defined as follows: Default is
Maximum with I²t in.
2.5.3 Reset time - Real time is counted up if the current exceeds the function threshold and counted down if the
current drops below the function threshold. Real time is set to zero when the curent drops below the power pickup
point.
2.5.4 Residual ground current - In a three phase, four wire system the ground fault functions can discriminate
between a ground fault and a neutral current.
2.5.5 Ground fault summing - The reset technique used for long-time and short-time function is applied. i.e, real time
is counted up if the current exceeds the function threshold and counted down if the current drops below the function
threshold. The ground function includes arcing ground summation for tripping. This feature allows arcing grounds
occurring sufficiently close together to be summed so that their magnitude will exceed the threshold setting of the
ground element.
2.6 Current Unbalance
2.6.1 Pickup settings - 5% to 50% in increments of 1% and DISABLED. These changes can be made either via the
keypad and LCD or the NIM communications unit. Default is DISABLED. The current unbalance function is only
available for systems with VIM attached.
2.7 Current Sensor Thresholds
2.7.1 Long time - 0.5X to 1.0X of sensor rating in increments of 0.1.
Short time - 2X to 10X of sensor rating in increments of 1.
Instantaneous - 3X to 12X of sensor rating in increments of 1.
Ground - 100 amps to 1200 amps
300 amps to 1200 amps
500 amps to 1200 amps
Depending on sensor rating. See section 2.5.1
2.8 Information Function
2.8.1 The information function consists of an LCD screen, a mechanical target, a light emitting diode (LED) and six
keypad buttons.
2.8.2 The mechanical target provides indication that the unit has caused a circuit breaker opening. Further
information about the function such as the type of trip, LT, ST, INST, GND, I UNB, V UNB, or UV and the fault
current is displayed when any keypad button in depressed after a trip has occurred, or can be found in the records
menu.

2.8.3 The target resets automatically when the unit is re-energized. Reset occurs in 2 seconds.
2.8.4 The red LED blinks once per second to indicate that the MPS-C 2000 unit is powered up and functioning
normally. (self monitor light).
2.8.5 The red self monitor light blinks five times per second to indicate long-time pickup and continues to do so until
reset or the breaker trips.
2.8.6 When the unit is powered up and the settings table has timed out, the LCD screen will display metering
information provided that the unit has enough line current to power up or is externally powered.
3. TEST FUNCTIONS
3.1 The unit continuously monitors the condition of the microprocessor and is reported by a flashing LED on the front
panel. Upon failure, the LED will glow steadily.
3.2 The unit is compatible with the 607 test set.
4. VOLTAGE INTERFACE MODULE (VIM)
4.1 The VIM performs the following functions:
a. Provides the phase voltage for remote display.
b. Houses the electronics for performing the power, power factor and frequency processing based
on current data from the MPS-C 2000 box.
c. Performs calculations to determine voltage unbalance and undervoltage faults.
4.2 If a VIM device is installed the MPS-C 2000 unit must be connected to a NIM communications unit.
