company news about The difference between the working principle of the fuse and the circuit breaker

(1) The working principle of the fuse is mainly based on the thermal effect of the current. When the current exceeds the fixed value (the fixing value of different fuses is different), the internal fuse will cause the melting to break and the fuse to achieve the circuit. Circuit, and the protection equipment is not burned by large currents

(2) There are many types of circuit breakers, and there are differences in structure principles. Generally, the inspirational of the check -up coil will cause the trail to perform the trip, because the current is too large. Of course, the circuit breaker can not only operate automatically, but also manually operate. Control the opening and closing action of the circuit breaker.
