VS1(ZN63)-12/630-20KA Circuit Breaker

VS1(ZN63)-12/630-20KA Circuit Breaker
Product Detailed
1. Advanced solid-insulated technology 2. A complete set of type tests 3. IEC standards 4. Excellent performance

Circuit breaker according to its range of application is divided into high voltage circuit breaker, and low voltage circuit breaker, high and low voltage line division is fuzzy, the 3 kv VS1(ZN63)-12/630-20KA Circuit Breaker of above call high-voltage electrical appliances. Low voltage circuit breaker is also called automatic switch, it is a kind of both the manual switch function, and can automatically loss of pressure, under voltage, overload, and short circuit protection appliances. It can be used to distribution power, not frequently start asynchronous motor, the power supply line and motor, to carry out protection, when they happen serious overload or short circuit VS1(ZN63)-12/630-20KA Circuit Breaker and under-voltage fault and can cut off the circuit automatically, its function is equivalent to fuse switch and owe thermal relay etc combination. And in breaking fault current after generally do not need to change parts, has gained a wide range of application.
