When ambient temperature exceeds the specified value, the inside bimetal of ST10 series motor protector will trip off to cut the circuit. When the temperature lowers down, the bimetal will reset and the circuit is connected again.
Auxiliary heater works together with bimetal, which can control the trip off time precisely. When the current exceeds the prescribed value, ST10 will cut the circuit immediately.
