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
Monitoring Application = Temperature
Supply Voltage = 24 V ac/dc
Contact Configuration = DPDT
Time Delay = <100 ms
Temperature Sensitivity = Overtemperature, Winding Temperature
Width = 22.5mm
Number of Poles = 1
Minimum Operating Temperature = -25°C
Current Range = Maximum of 3.7 mA
Dimensions = 103.7 x 22.5 x 85.6 mm
