SETsafe | SETfuse thermal protector (TMS) mainly uses bimetal disc to sense current or temperature. When the temperature of the bimetal disc reaches the pre-calibrated temperature, the bimetal disc quickly trips, connect or disconnect the circuit. Ambient temperature increasing or current increasing or both of the above may cause the temperature of the bimetal to reach its pre-calibrated temperature, thereby connect or disconnect the circuit. This device covers rated current from 0 to 20 A, rated operating temperature from 30 °C to 175 °C by various part numbers. It complies with RoHS and REACH environmental protection requirements.
