EATON MP-3000 SAFETY RELAY 66D2032GX1 5A
MP-3000 Motor Protection Relay
IM02602002E
Instruction Leaflet for Installing, Operating, and Maintaining the
relay that is easy to set up and use. It monitors, controls, and protects
motors against overload, thermal damage to rotor or stator, electrical
faults, and excessive starting, and many process equipment failures.
Advanced algorithms and thermal models give safe operation over a
wide range of conditions.
The MP-3000 protects 50 or 60 Hz three-phase motors of any size
or voltage level. It can protect induction or synchronous motors, with
or without RTDs. The relay is frequently installed in motor starters or
switchgear.
The MP-3000 Motor Protection Relay provides the following pro
tection, alarm, and control functions. ANSI device numbers are in
parentheses.

MP-3000 features and Enhancements
The MP-3000 Motor Protection Relay incorporates the field proven
motor thermal models and sequence component measurement
techniques that were pioneered in the IQ 1000 II relay thermal models.
The MP-3000 also adds several enhancements. Significant enhance
ments and features include:
1. Recognized to meet UL 1053 Standards for Ground Fault Protec
tion Devices.
2. Power supply operates continuously at 55% of nominal supply
voltage. It can ride through a voltage sag or loss for 30 cycles
without dropping out and taking the motor off line.
3. Optional Quick Release Drawout Case that makes removal and
replacement fast and easy.
4. New Armed/Disarmed feature for trip-free installation with Quick
Release Drawout Case.
5. User selectable trip or alarm only on relay internal failure detec
tion.
6. Real-time clock for date and time stamping of trips, alarms, and
events (Y2K compliant).
7. Expanded memory for extensive recording and logging of events,
trips, alarms, history, and motor starting current profiles.
8. Motor starting profile plot versus protection limits.
9. Easy-to-use faceplate and user interface. Settings and data are
organized into pages under six main modes. The modes are
Default (motor state), Monitor, View Setting, History, Logs, and
Program (change settings).
10. intel-i-trip Intelligent Overload Protection with adaptive trip char
acteristics based on RTD readings and motor operating history.
11. RTD diagnostics and communications error checking for addi
tional security against operation from RTD failures.
12. Mechanical Process Load Shedding feature provides overload
indication to control upstream processes, averting unnecessary
motor overload shutdown or jam trips, and maintaining process
continuity.
13. Download settings or retrieve metered and historical values via
the communications port.
14. Flexible user-configurable inputs and outputs for broader applica
tion.
15. Options for transition function control and monitoring on time
and/or current.
16. Emergency override function resets jogging limit functions and
clears thermal model bucket to permit restart with a time-tagged
event log. Unit uses a secured button; this function can be dis
abled.
17. Relay can be programmed while motor runs, and new settings
are all put into effect at once in a controlled fashion. Or, User can
set unit so programming is allowed only after motor stop.
