WLM6RT series adjustable type of moulded case circuit breaker is one of the new circuit breakers researched and developed by us with international advanced technology. It has the characteristics of zero flashover, high breaking, box-type accessories, small and compact structure, green and environmental protection. By rated limit short-circuit breaking capacity (Icu), the circuit breaker is divided intoC type(economic ) S type (standard), M type (relatively high breaking) and H (high breaking). It is an ideal product for power distribution and motor protection. It has the rated isolation voltage of 800V. It can be used for occasional circuit switch and startup of motor in circuits with the rated working voltage ≤690V and rated current of 10A-2000A.
