Circuit breakers "rejecting" fault circuit "rejecting" a big threat to the safe operation of the system, when a device fails, the circuit breaker tripping, will make the electrical equipment burned or grade trip caused by power supply breaker trip outdoors vacuum circuit breakers, so that the disappearance of the bus voltage substation, causing widespread power outages. Therefore, we must understand the probable "rejecting" the reason and the occurrence of how to "rejecting" after the failure of the process! Welcome to inquire buy! Breaker breaker, also known as air switch, also known as automatic switches, low voltage circuit breakers. The principle is: when the operating current exceeds the rated current, short-circuit, loss of pressure, etc., automatically cut off the circuit. Currently, the total household switch common with knife switch with porcelain insert Insurance (which has been eliminated) or air switch (with leakage protection MCB). Currently DZ series home use air switch circuit breaker factory outlets, a common model / specification: C16, C25, C32, C40, C60, C80, C100, C120, and other specifications, where C represents the tripping current, namely the current take-off, For example C32 represents the take-off current of 32A, 6500W heater is usually installed to use the C32, installation 7500W, 8500W heater use of open space C40. Outdoor high voltage vacuum circuit breaker, breaker Lhasa, Xian Huayi Huayi electricity supplied by the power plant.
