Products Overview:
DW45 series intelligent air circuit breaker is used for control and protection of low voltage distribution network. General installation in low voltage power distribution cabinet as main switching function of total protection. Rated current of 1000A and circuit breaker below, also can be used for motor protection. The product provides wet tropical type (TH type), marine and type 1E circuit breaker, provide low temperature to -40 Deg. C breaker, and can provide a liquid crystal display and digital display circuit breaker. For the "China famous brand" products.
