MCB,Miniature Circuit Breaker is an electromechanical device designed to protect an electric circuit from over-current - A term to describe an electrical fault caused by either overload or short circuit.
MCBs improve on this functionality as they are usually not destroyed during over-current so are reusable. They are also much easier to use, offering the convenience of 'on/off switching' for circuit isolation and since the conductor is housed within a plastic casing, they are much safer to use and operate.
Timelec MCB , offering short-circuit, overload protection, meeting the standard of IEC/BS EN 60898-1 and GB10963.1, and it selectively protect the human being from hurt. For example, it breaks the circuit when it detects overload which is a common and dangerous in home-wiring, it would trip to cutout the electric current.
