Circuit Breakers and Switches

A circuit breaker is an electrical switch that is designed to protect an electrical circuit from damage due to a short or overcurrent/overload circuit. The basic functionality is to prevent the current flow after protective relays detect a fault.
There are many types of circuit breakers such as miniature circuit breakers, motor protection circuit breakers, air circuit breakers, and earth leakage circuit breakers. Each circuit breaker served a different purpose. Essentially, when excess current is detected, they’re designed to trip a mechanism to break the circuit.
 
Switches are used to turn on or turn off the electrical lights, connected equipment, or electrical outlets. To keep up with the challenges faced in security and convenience, there are switches that extend control and safety to the building infrastructure.
We have a wide range of circuit breakers and switches from various brands such as ABB, Omron, Schneider Electric, Fuji Electric, and more.
