Circuit breakers, also known as the air switch, also known as automatic switch breaker factory direct, 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, 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, such as C32 represents takeoff current of 32A, 6500W heater is usually installed to use the C32, installation 7500W, 8500W heater use of open space C40. Common fault interrupter electrically before closing operation if the red, green not lit, no power or control circuit controls have broken phenomenon. Check whether the control power supply and the entire control loop elements normal, when the operation switch on the green light flash circuit breaker, and the red light does not shine, no indication meter high voltage vacuum circuit breaker factory outlets, horn ring, mechanical breaker points, closing The position indicator is still OFF position, then the operating handle position and the position of the circuit breaker does not correspond to the circuit breaker is not closed. The common causes are: the closing circuit fuse blown or poor contact; closing contactor is not activated; closing coil failure. When the operation switch on the circuit breaker, the green light goes out vacuum circuit breaker factory direct, instantaneous bright red and then goes out, the green light and flash and there is horn ring, indicating then automatically trip the circuit breaker is closed. The reason may be caused by protection circuit breaker tripping or closing circuit breaker mechanical fault can not be maintained in the closing state of the circuit breaker on the fault line. If the green light flashes when the operation switch on or off, the red light does not shine, but meter indicating mechanical points, closing position indicator in the closing position, indicating that the circuit breaker has been closed. Probable cause poor contact breaker auxiliary contacts, for example, is not disconnected from the normally closed contacts, normally open contact is not closed, resulting in a green light flashes and the red light does not shine; closing the loop may be broken or closing red burn .
