Vacuum Circuit Breaker

A 12kV Vacuum Circuit Breaker (VCB) is a high-performance electrical switching device designed to handle medium-voltage power distribution systems. It ensures safe and reliable operation by interrupting fault currents and isolating electrical circuits during abnormal conditions. Vacuum circuit breakers are widely recognized for their efficient performance, minimal maintenance, and long operational life.

Key Features

• High Voltage Capacity:

  Designed to operate efficiently at 12kV, making it suitable for medium-voltage power systems.

• Vacuum Interruption Technology:

  Uses a vacuum as the arc-quenching medium, which ensures rapid arc extinction and minimal energy loss.

• Compact and Robust Design:

  Features a compact structure that is both durable and capable of withstanding harsh operating conditions.

• Minimal Maintenance:

  The absence of gas or oil in the arc chamber reduces maintenance requirements compared to other circuit breakers.

• High Fault Interrupting Capability:

  Capable of handling high fault currents and ensuring safe operation in power distribution systems.

• Eco-Friendly:

  With no greenhouse gases involved, vacuum technology contributes to environmentally sustainable operations.
