Circuit breaker fuse in China in London

What is a Type C fuse?

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. Type C fuses trip circuits when the current exceeds the rated one by between five and ten times - i.e. at 100-500 amps for a 20amp device.

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.

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.

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.
