Vacuum Circuit Breaker

We offer half panels and sub-cubicles for 11kV. The VCB is ‘draw out’ type and can be racked out directly on the floor. VCBs are type tested according to International Standards IEC-62271 at renowned laboratories. They are compact, safe and reliable. The sub-cubicle is VCB with its compartment having all safety interlocks. The half panel is an assembly of the medium voltage compartments except for low voltage compartment.
