Description
The MPS Motor Protection System monitors voltage, current,
and temperature to provide a comprehensive package of
22 protective functions. The MPS is a modular system with
integrated protection, motor control, metering, and data-logging
functions. This system is typically used to provide protection for
three-phase low- and medium-voltage, medium-
to high-horsepower induction motors.

Phase Current Transformers
Phase CTs are required to detect phase
currents.
Ground-Fault Current Transformer
Required zero-sequence current transformer
detects ground-fault current. Available with 5-A
and 30-A primary ratings for low-level pickup.
MPS-RTD Temperature Input Module
Optional module provides 8 inputs to connect
Pt100, Ni100, Ni120, and Cu10 RTDs.
MPS-DIF Differential Current Module
Optional motor differential protection,
compatible with core balance and summation
current transformer connections.
