MCB, Miniature Circuit Breaker meets the standard of IEC/BS EN60898-1, GB10963.1. It is an electrical safety device to protect an electrical circuit from damage caused by overcurrent and short current. Unlike a fuse which operates once and then must be replace, a miniature circuit breaker can be reset to resume normal operation. Timelec MCB is applicable in power distribution system of domestic, commercial and industrial buildings to protect and control circuits for overload and short-circuit protection. It can be combined with shunt tripping, under-voltage and overvoltage tripping, Auxiliary, Alarm and other electrical accessories.
Keep your electrical systems running smoothly with Timelec's premium MCBs! As a leading MCB manufacturer in the industry, we're committed to delivering top-notch circuit breakers that meet the highest standards of quality and reliability.
