Product Introduction

Production Introduction

VS1-12 Vacuum Circuit Breaker is an indoor switchgear component with rated voltage of 12kV and AC 50Hz.

VS1-12 Vacuum Circuit Breaker conforms to GB1984-2003 "AC High Voltage Circuit Breaker", JB3855-1996 "3.6~40.5kV Indoor AC High Voltage Vacuum Circuit Breaker", DL403-2000 "12~40.5 kV High Voltage Vacuum Circuit Breaker Ordering Technical Conditions" and the International Electrotechnical Commission IEC62271 -100:2001 "High Voltage AC Circuit Breaker" and other standards.

As the protection and control unit of power grid equipment and power design of industrial and mining enterprises, VS1-12 Vacuum Circuit Breaker are suitable for switching loads of different natures and frequent operations, and breaking short-circuit current many times.

VS1-12 Vacuum Circuit Breaker adopts a new type of circuit breaker operating mechanism, and the primary part can use international brand solid-sealed poles to seal the vacuum interrupter and the main conductive circuit parts into a whole to protect the interrupter from collision, dust and condensation.
