thermistor overload relay

A thermistor protection relay uses thermistors which are built inside the motor and measure the temperature of the motor windings. If the motor gets to hot, the thermistor relay will trip. An overload relay must always be used, a thermistor relay is only usefull if you are using the motor in S6 mode (temporary overload).

The thermistor motor protection relays CM-MSS.32 and CM-MSS.33 monitor the winding temperature of motors and protect them from overheating, overload and insufficient cooling. The devices are available with two different terminal versions. You can choose between the proven screw connection technology (double-chamber cage connection terminals) and

Thermal overload relays are conversely designed to measure a motor's heating profile; therefore, overload must occur for an extended period before the circuit is interrupted. Temperature control relays directly sense a motor's temperature using a thermistor or resistance thermal device (RTD) probe which is embedded in the motor winding

CT Thermal Overload Relays, KTA Motor Circuit Control-lers or the CET4 Electronic Motor Protector. Theory of operation Thermistors are installed in the ther-mally critical locations of the device to be protected. For motors this is the stator winding. The resistance of the thermistors has a positive temperature coefficient (PTC). The resistance of

The EMT6 thermistor motor-protection relay from Eaton’s Moeller series protects equipment against overtemperatures caused by heavy starting duties, braking, undervoltages, overvoltages, and high switching frequencies. The temperature is monitored by means of a thermistor sensor located directly at the motor winding. All EMT6 relays are suitable for global use.
