- The ZMW1 universal circuit breaker is a new – type circuit breaker developed by our company’s R & D technology. The product features small size, high breaking capacity, multiple functions, etc.
- The ZMW1 is suitable for general power distribution systems, new energy power generation and distribution systems, multi – power – source power distribution networks, inverters, and scenarios for grid – connection operation and protection of rotating motor – type power sources in distributed power sources.
- The ZMW1 complies with the GB14048.2 – Category B of the circuit breaker standards.
- AC – 3 category of use:
- The rated working voltage of the circuit breaker is 50Hz, AC400V/690V;
- The rated current of the circuit breaker is 200A ~ 1600A; The circuit breaker has three – pole and four – pole types;
- It has draw – out type and fixed type;
- It can be connected by reverse incoming line;
- It has an isolation function, with the symbol “__/| – × – ”.
- The circuit breaker complies with the following standards:
- IEC60947 – 1 and GB14048.1 – 2012 General Rules for Low – voltage Switchgear and Controlgear;
- IEC60947 – 2 and GB14048.2 – 2008 Circuit – breakers for Low – voltage Switchgear and Controlgear;
- IEC60947 – 4 – 1 and GB14048.4 Electromechanical Contactors and Motor Starters (including motor protectors) for Low – voltage Switchgear and Controlgear;
