DW45 series of low-voltage intelligent vacuum circuit breaker (hereinafter referred to as circuit breaker) is mainly used for AC 50Hz, rated working voltage 400V, 690V and 1140V, rated working current 630A to 1600A distribution network, used to distribute power, Power equipment suffered overload, under voltage, short circuit and single-phase ground fault and other hazards. In normal conditions can also be used as a frequent conversion of the line. Circuit breaker core components using intelligent release, with precise selectivity protection, to avoid unnecessary power outages, improve power supply reliability. The biggest feature of the circuit breaker is the use of vacuum interrupter, breaking current in the process of no arc discharge, which is particularly suitable for coal, chemical, smelting and other environmental conditions in poor places.
Products meet GB 14048.2 and IEC 60947-2 standards.
