When a circuit failure or abnormal , with the rising current , and the increased current may damage some of the important components in the circuit devices or expensive , or even burning of the circuit may also cause a fire . If the circuit is properly placed fuse and fuse holder , then the fuse will be in the current exception is raised to a certain height and heat when their fuse cut off the current , and thus play a role in protecting the safe operation of the circuit . One kind of action with a fuse of the same material .
MCCB can automatically cut off the current when the current exceeds the trip . Molded plastic insulator refers to as a shell device used to isolate between the conductor and the grounded metal parts. MCCB as a low-voltage distribution system and motor protection circuit overload , short-circuit protection , is very wide application products . With modern technology, the level of the continuous development of new technologies, new processes, new materials emerging, production technology and the continuous improvement of various materials breaker , the performance of the circuit breaker has been greatly improved , in addition to well-known international brands such as ABB, Schneider , some domestic enterprises to be outdone, self- development, development or introduction of foreign advanced technology, and to be digested , absorbed, but also to market a mature product . These products have zero arcing , high breaking , large capacity , inlet and outlet direction can be interchangeable , intelligent, four -pole, modular structure internal accessories , installation building blocks , small volume and other characteristics . MCCB achieve selective protection required and a variety of auxiliary functions , and with a communication interface that allows low-voltage distribution system automation and networking possible ; reduce the dynamic low-voltage power distribution equipment , requiring thermal stability ; reducing the volume of power distribution equipment ; greatly improve the reliability of power supply and distribution systems and equipment operation.
