 It is used for protecting against overload and short circuit in illuminating and power distribution system,and also can be used for switching the infrequent operation of circuit.
Overload protection: When the load current is more than rated current,the bend of dual metal taminate sheet is caused that will strike tripping mechanism and break electrical equipment for the thermal-expansion coefficient of the twoo kinds of metals of the thermal tripping dual metal laminate sheet is different.
Short circuit protection: when takes place short circuit,the magnetic field produced by current flowing over induction coil will drive the lever to make the circuit breaker trip quickly.
