DW10-10 type multi-oil circuit breaker is installed outdoors, and is mainly used for outdoor 10KV power grid load operation, as a sub-load, combined load current overload and short circuit fault protection.
The circuit breaker is a three-phase common box. Each phase has a simple circuit breaker, and it is also used for the insulation of the arc-extinguishing and conductive parts to the ground. Automatic overload release and time-delay device, the operating mechanism is integrated into the circuit breaker body at the front end of the box cover.
Before use, the circuit breaker must be opened for adjustment and inspection. Since this circuit breaker is shipped without oil, the insulating cardboard bushing is extremely susceptible to moisture, and the insulating cardboard bushing must be dried.
