Product Details
CM-MSE Thermistor Motor Protection Relays
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:
Heavy duty starting
Increased switching frequency
High ambient temperature
Insufficient cooling
Break operation
Unbalance
Increased switching frequency
High ambient temperature
Insufficient cooling
Break operation
Unbalance
The relay is independent of the rated motor current, the insulation class and the method of starting.
Automatic reset
Connection of several sensors (max. 6 sensors connected in series)
1 n/o contact
