A circuit breaker is a necessary part in houses, buildings and establishments today. They are the first line of defense against fire that is caused due to overheating, poor wiring, etc. Considered as the most important safety mechanism, they instantly react once they sense that there’s too much flowing current into their system. They automatically shut the supply of electricity, only resuming if something has been done to fix the issue.

Unlike a fuse that only works once, circuit breakers can be used multiple times. Their designs make it possible to be used over and over again. They are produced with a switch that is attached to either an electromagnet or a bimetallic strip. These circuits have hot wires that are attached on the switch’s two ends. Once the switch is turned on, power is able to pass from the bottom terminal to the electromagnet, moving contact, stationary contact and upper terminal.

Re-closer, Magnetic Circuit Breakers, Common Trip Breakers, Carbon dioxide high voltage circuit breakers, Low-voltage Circuit Breakers, Medium-voltage Breakers, Residual-Current Breakers and Residual-Current Device are some of the types of circuit breakers that are commonly used in the market. These variations are produced to meet the different levels of electricity required in a number of fields and areas.
