VS1 Indoor High-Voltage Vacuum Circuit Breaker

Ceho can offer VS1 Indoor High-Voltage Vacuum Circuit Breaker with comprehensive after-sale service and timely delivery. The working principle of this vacuum circuit breaker is that when the moving contact and the static contact are separated under the action of the operating mechanism, an electric arc is generated between the contacts, and the surface of the contacts volatilizes steam at high temperatures. The special shape of this product contact design generates a magnetic field when current passes through. Under the action of this magnetic field, the electric arc moves rapidly along the tangential direction of the contact surface. Some metal vapor condenses on the metal cylinder (shield), and the arc naturally passes through zero and then goes out. When the arc goes out, the dielectric strength between the contacts recovers rapidly
