Thermistor Motor Protection Relay
BA 9038
The thermistor motor protection relay BA 9038 is used to protect against thermal overload of motors caused by high switching frequency, havy duty starting, phase failure on one phase, bad cooling, high ambient temperature. Also the temperature monitoring of bearings, transmissions, oil and cooling liquids is possible. Up to six thermistors can be connected via the input.
