Types of VS1 Vacuum Circuit Breaker
Great at Putting Out Arcs
VS1 Vacuum Circuit Breaker uses a high quality vacuum interrupter that’s sealed tight. It kills the arc fast when the current hits zero. It can handle big short-circuit currents, and the insulation bounces back quickly after it trips. That means less chance of restrikes and steady operation no matter the load. Your power system stays safe and sound.
