DW17 series; ACB (hereinafter referred to as the circuit breaker) is based on the prototype ME and improving digestion. The use of open modular structure, with a small size, light weight, strong family of interchangeability of parts and components, and the protection of full-featured, on-off capability, high-technology economic indicators, the maintenance of easy to use and so on.
Circuit breaker rated voltage applied to the exchange of 380V, 660V, 50Hz power distribution circuit for non-frequent conversion. On the lines and electrical equipment overload, short circuit and under voltage protection, and choice of protection levels with a direct start-up motor, generator and rectifier devices.
