Introduction

 

DW15 series universal circuit breaker (hereinafter referred to as circuit breaker) is suitable for AC 50Hz, rated current to 630~4000A, rated
It is used in the distribution network of working voltage AC 380V to AC 1140V to distribute electrical energy and
Load, under voltage, short circuit protection. Can also be used to protect the motor from overload and under-current in AC 50Hz, 380V grid
Voltage and short circuit.
The circuit breaker can be used for infrequent conversion of the line under normal conditions, and can also be used as a non-motor in normal conditions.
For frequent starting, the circuit-breaker with rated current of 630A in the shell frame also has a drawer structure and a current-limiting circuit breaker.
Due to the current-limiting characteristics, current-limiting circuit breakers are particularly suitable for networks where large short-circuit currents may occur.
Conform to the standard GB 14048.2 IEC60947-2

 

Feature

 

The O circuit breaker is a three-dimensional layout, and the contact system, fast electromagnet, and left and right side panels are all installed on an insulating board.
O The left side is equipped with a shunt release, and the back is equipped with an undervoltage release connected to the trip half-shaft.
O three-dimensional layout, contact system and operating mechanism are installed on the iron frame.
O. There is an arc extinguishing system on the upper part and an operating mechanism on the right.
O circuit breaker body and drawer seat; the drawer seat is composed of left and right side plates, aluminum bracket, isolation contact seat, secondary circuit static contact, sliding frame, etc.
O The circuit breaker body is equipped with isolation contacts, secondary circuit moving contacts, grounding contact support rails, etc.
