Product Description

Application

VS1-12 series permanent magnet type indoor AC high voltage vacuum breaker is used in the system of AC 50Hz, rated voltage 12KV, three phases, to protect and control the network equipment ad power distribution in industrial mining enterprises. It can operate frequently at rated voltage, or break the short circuit current many times

The operating mechanism is assembled on the breaker body integrally then to be fixedly mounted, also installed on push-in mechanism and form a breaker trolley

Normal service conditions

This type operated with dual steady permanent magnet mechanism, the magnet body built inside the mechanism, provide holding force to remain the breaker in ON, OFF position, compared with common spring mechanism, the number of mechanical parts are reduced, mechanical driving linkage is shortened, all of these can improve the reliability of the breaker, mechanical endurance also will be increased much.
