Model Number

DW17(ME) Series

Features Specifications: DW17 Series Multi-purpose Circuit Breaker

Application:

DW17 Series multi-purpose Circuit Breaker are applied to AC50Hz circuit of rated 380V \ 690V to distribute electric energy .to switch the circuit infrequently, or to protect the power distribution system, motor and so on devices from overload, under voltage and short circuit. The breaker rated 630A or below can be used in AC 50Hz 400V network to protect the motor from overload and short circuit to start the motor infrequently under the normal conditions.

Structure Character

      The circuit breaker adopts three-D type pyramid structure,and it is classified into four shell-bracket current levels,namely,630-1650A,2000-3205A,3200-3205A and 4000-4005.630-1605 shell bracket is the basic of the four,and other shell brackets are fixed together respectively in pyramid structure according to different rated current. The circuit breaker is comprised of framework,contactor system,arc extinguish system,dropout device,operation mechanism,drawer base,sword-insert base,and 2-time connecting loop.The general structure is classified into two types,fixed type and drawer type,and extra long direct rail is available in the later for convenience of repair.Wiring pattern is divided into vertical type and horizontal type,and operation patterns are manual operation,electric rapid operation,and electric presorted energy operation.Over current dropout device of the circuit breaker is comprised of instant type,long time-relay type,and short time-relay type.Users may make a combination according to practical requirements to realize one-stage or two-stage protection.
