EATON VICKERS EEA-PAM-535-A-32 AMPLIFIER CARD KFDG4V-5 2326003
The MP-3000 Motor Protection Relay is available in either a fixed
mount, semi-flush case, or in a semi-flush Quick Release drawout
case. Both housings are compact and fit a standard IQ cutout.
The optional Quick Release drawout case features 2-stage contact
disconnects and self-shorting current transformer (CT) circuit terminal
blocks. A spare self-shorting terminal pair is available for use as a
relay removal alarm, or to keep the contactor energized for continu
ous motor operation on relay removal. The optional communications
modules (PONIs) are externally mounted on the fixed mount case and
internally mounted in the drawout case.
The MP-3000 has 3-phase current inputs and one ground current
input. Both 5 A and 1 A versions are available. The ground protection
and metering functions are best used with a zero sequence ground CT,
rather than from the residual connection of the phase CTs. The zero
sequence ground CT provides greater ground fault sensitivity. The unit
is User-programmable for 60 Hz or 50 Hz operation.
The MP-3000 has two discrete inputs, four form C (1 N.O. and 1 N.C.)
output contacts, and one 4 to 20 mA analog output. The relay lets the
User program the operation of all the I/O points, except for the trip out
put. In addition, the relay has 10 LEDs for the indication of protection
on, program mode, monitor mode, view setting mode, history mode,
log mode, trip, alarm, and Aux 1 and Aux 2 output relay operation. A
test page in the program mode provides a display indication of the
discrete input states and testing of the output relays, target LEDs, and
analog output circuit.
A User-friendly operator interface provides quick access to the set
tings, monitored values, motor history, and operational logs. A large
LED alphanumeric display provides easy viewing from any angle.
Simple keypad operations provide quick and easy navigation through
all settings and stored data. The program mode and emergency over
ride buttons are access-restricted via a seal and latched cover. An
integrated context-sensitive help button provides an online descriptive
display of functions, abbreviations, and operations.
2.1 Optimum Motor Protection
The MP-3000 Motor Protection Relay has been designed for maximum
motor utilization and protection. It is desirable to run the motor as
close as possible to its design limits, while protecting it against exces
sive heating and damaging overload conditions. The MP-3000 has

ield-proven protection algorithms developed from basic motor design
principles and operating parameters.
The MP-3000 protects against rotor and stator overheating, short
circuits or insulation faults, excessive starting duty, and abnormal
operating conditions.
2.1.1 Intel-I-Trip (adaptive I2t Motor Overload Protection)
Motor operation is typically limited by the rotor thermal capabilities, but
the measuring quantities are stator currents. This requires accurate
measurements and good motor thermal models to provide maximum
utilization and reliable protection.
The MP-3000 uses the field-proven Intel-I-Trip overload measure
ment and motor thermal protection model that uses the manufacturer’s
nameplate data to develop an overload protection curve specifically for
the motor being protected. When RTDs are used, the Intel-I-Trip over
load protection curve becomes adaptive. The overload trip times will
change based on the modeling impact of the motor’s internal tempera
ture data. It also trips directly for high stator temperature
