What is the main function of low-voltage fuse is? A: The main is to achieve low-voltage distribution system short-circuit protection, low voltage switch cabinet how? Some can achieve its overload protection. What is the main function of low voltage knife switch is? A: The no-load operation, Taikang low voltage purchase, for isolation switch. What low-voltage fuse switch and load switch main functions? A: The low-voltage fuse switch has a dual function knife switch and fuse. The main function of effective load switch off load current, low voltage, short circuit protection can be performed. What is the main function of low voltage circuit breaker? A: both off-load circuit, low voltage switch cabinet Yanjin County principle, can automatically trip the short circuit, overload and loss of pressure. MCCB SZRM1SZRM1 series molded case circuit breaker (hereinafter referred to as breaker) is mainly used for AC 50Hz (or 60Hz) rated insulation voltage 690V, rated working voltage 400V, rated current 1250A and below the distribution network as assigned power and protection circuit and power supply overload, under voltage and short circuit protection, circuit breakers 400A frame degree or less can also be used as motor overload, under voltage and short circuit protection, under normal circumstances can be used as infrequent line conversion and motor The infrequent start with.
