CM-MSS Series Thermistor Motor Protection Relays


Heavy duty starting

Increased switching frequency

High ambient temperature

Insufficient cooling

Break operation

Unbalance

The CM range of thermistor motor protection relays are used to control motors equipped with PTC temperature sensors. The PTC temperature sensors are incorporated in the motor windings to measure the motor heating. This enables direct control and evaluation of the following operating conditions:

Main features include:

Dynamic interrupted wire detection

Wide control supply voltage range for this series 24-240 V AC/DC

Short circuit monitoring of the sensor circuit

Non-volatile fault storage

Remote reset

Screw connection technology or Easy Connect Technology available

Single Sensor Input Version

Wire Break Detection

Approvals

Some products also have the ATEX approval for the use in hazardous areas.
