Product description

I.The scope of application and use

DW15 series universal circuit breaker (hereinafter referred to as circuit breaker) is suitable for distribution network with AC 50Hz, rated current up to 1600A, rated working voltage to 1140V (shell rated current 630A) or 380V (shell rated current 1600A). Used to distribute electrical energy and to be used as overload, undervoltage, and short circuit protection for line and power equipment. Circuit breakers with a frame rating of 630A can also be used as overload, undervoltage and short circuit protection for motors in AC 50Hz, 380V networks.

The circuit breaker can be used as an infrequent conversion of the line under normal conditions. The circuit breaker with a frame rated current of 630A can also be used as an infrequent conversion of the motor under normal conditions.

III.Structural characteristics

1, DWl 5-630 universal circuit breaker

The circuit breaker is in a three-dimensional arrangement, and the contact system, the quick electromagnet, and the left and right side plates are all mounted on an insulating plate. The upper part is equipped with an arc extinguishing system, and the operating mechanism can be mounted directly in front or on the right side. There are "minute", "close" indications and manual disconnect buttons. The upper left is equipped with a shunt release and the back is equipped with an undervoltage release connected to the trip half shaft. The fast saturation current transformer or current-voltage converter is placed on the lower busbar. Undervoltage delay devices, thermal relays or semiconductor trip units can be mounted separately below.

2、DW15-1600 universal circuit breaker

The circuit breaker is in a three-dimensional arrangement, and the contact system and the operating mechanism are all mounted on the iron frame. The upper part is equipped with an arc extinguishing system and the right side is equipped with an operating mechanism. There are “pass”, “off” indications and manual “close” and “minute” buttons. The left side is equipped with a shunt release and an undervoltage release. The fast saturation current transformer or current-voltage converter is placed on the lower busbar. Undervoltage delay devices, thermal relays or semiconductor trip units can be mounted separately below.

3、DW15C low voltage drawer circuit breaker

The product consists of a circuit breaker body (modified DW15) and a drawer. The circuit breaker body is provided with an isolation contact knife, a secondary circuit moving contact, a ground contact support guide rail and the like. The drawer seat is composed of left and right side plates, aluminum brackets, isolation contacts, secondary circuit static contacts, and carriages. Directly below, the operating device is composed of a rocking handle, a screw, and the like.

Note:

1. 630A is 0.2s and 1600A is 0.4s.

2. The arcing distance of the 1140V specification is 350mm.

3. The DW15C circuit breaker has a mechanical life of 200 cycles and an I c u of 50 kA at 3 80 V.

4. The bracketed indicator is only applicable to circuit breakers with In≤200A.

5. Fix the limit current breaking capacity of 100kA when the current limiting circuit breaker is fixed at 3 80 V.
