Hot sale blown fuse in circuit breaker supplier

What is a fuse & how does it work?

A fuse is an electrical component designed to protect electrical circuits by safely opening the circuit under abnormally high current loads. Fuses come in many shapes and sizes, but each one is designed to protect a circuit with a specific set of electrical parameters.

What are striker fuses?

Striker fuses are fuses fitted with a spring-loaded striking device that can trip adjacent switches and also indicate that a fuse has blown. A Type C fuse is actually a type of miniature circuit breaker (MCB). MCBs are a type of circuit breaker used with lower-powered circuits to cut off current in the event of an overload.

Why is a fuse used instead of a circuit breaker?

A fuse is an electrical safety device that protects an electric circuit from excessive electric current. Fuses are destroyed during overload conditions. When reasonable to do so (and economically sensible), circuit breakers are used instead because they are not destroyed during overload conditions.

Why are fuses a cost-less solution for overcurrent protection?

Fuses are cost-effective compared to other protective devices such as circuit breakers, making them a cost-less solution for overcurrent protection. Fuses provide quick protection against electrical defects by rapidly interrupting circuit current in the case of an overcurrent condition.
