A circuit breaker (CB for short) is an electrical safety device used to protect a circuit from overcurrent or short-circuit damage. 

Its basic function is to interrupt the current (cut off the circuit) to protect equipment (appliances in the circuit) and prevent Fire risk, can close and open circuit (ON/OFF POWER), widely used in industrial production and daily life. Aliases: air switch, safety switch,non-fuse switch (NFB).

These box-like devices work by limiting the current in a single circuit. Without circuit breakers, your facility is in constant danger and chaos.

Circuit breaker type

There are two types of standard circuit breakers: single-pole circuit breakers and double-pole circuit breakers. 

These are simpler circuit breakers that monitor the rhythm of electricity as it circulates through indoor spaces.
