MCB (miniature circuit breaker) is an automatically-operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and immediately discontinue electrical flow. Unlike a fuse, which operates once and then has to be replaced, the miniature circuit breaker can be reset to resume normal operation.
Application
ANDX-D mini circuit breaker is mainly suitable for overload and short circuit protection. It is especially used for illumination and distribution in industry and commerce etc. It has pleasing outlook & high breaking capacity, reliable performance, high inflammable resistance and shock resistance for long service life.
It is within the circuit of AC 50/60Hz, rated voltage of single pole up to 230V,two three or four poles up to 415V. It can also be used for an unfrequented change over of the circuit and illumination under normal conditions.
