Circuit Breaker Products
Miniature Circuit Breaker (MCB) The first consideration when selecting electrical equipment or gadgets is safety. When the power fluctuates or an excessive amount of current flows, it produces damage in the form of an overload or short circuit. Therefore, it is vital to include a device as a safety factor to safeguard electrical devices/circuits against overcurrent. In the early days, the fuse was one of the most popular devices used to safeguard the circuit. A fuse has a metal wire or strip that melts when an excessive current flow occurs, therefore interrupting or halting the passage of electricity.
