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

2005/3/11 · 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

Thermistor Monitoring Relays. Adding thermistors to a relay allows to monitor coil temperatures for full-scale motor protection.

Thermistor Overload Relay: IEC Rated operational current at 230 V: UL/CSA Pilot Duty Rating: Rated Operational Voltage Range: 3: B 300: 24 -240 V 50/60 Hz, 24 - 240 V DC • With Overload Relay EMT6 Overload monitoring system for machines operating in the EEx e area 07/03 AWB2327-1446GB :

The CM range of thermistor motor protection relays are used to control motors equipped with PTC locked rotor, extent of permitted overload etc.

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
