WEM1 Series Plastic Case Circuit Breaker
Product number:
Classification:
Summary Description:
WEM1 series plastic case circuit breaker, is the company's comprehensive use of international advanced technology, the development of new products-"transparent circuit breaker". The circuit breaker adopts the design concept of visual transparency, novel and beautiful, providing an intuitive visual breakpoint for the operator, and can directly observe the state of the contact. It is applicable to the distribution network with AC 50Hz, rated working voltage to 400V and rated current to 800A for infrequent conversion and infrequent starting of motors. Circuit breaker with overload and short circuit protection function, can protect lines and electrical equipment from damage. It has the characteristics of small size, high breaking, short arcing (zero arcing in some specifications), and is an ideal product for land use.
