Product Description

General Introduction

GSW3 ACB could be suited for distribution net including frequency: 50Hz, rated voltage: 400V, 690V, rated current: 2000-7400A; And used for assigning the electrical energy and the protection line and the power equipment exempting such as overload, under voltage, short circuit, and single-phase earth harm, the circuit breaker has the intellectualized protection function, the selective protection is precise, which can enhance the power supply the reliability, and avoid the nonessential power cutmcompact structue, small volume and high breaking capacity, the seal contact system establishing zero over flash, the intelligent controller has test, load monitoring, great information dispiay, real-time programming and communication function, which might establish perfect three sections or four sections of protections.
