   Product Description

·         An 11/33 kV Vacuum Circuit Breaker (VCB) panel is a crucial component in medium-voltage electrical distribution systems, operating at a rated voltage of 11/33 kilovolts (kV).

·         It houses a vacuum circuit breaker, which is responsible for interrupting the flow of electrical current to protect equipment and personnel from faults like overloads and short circuits.

·         It's an enclosure containing a Vacuum Circuit Breaker (VCB) and associated control, protection, and metering devices.
