Circuit Breakers come in draw-out or fixed configurations.

Medium Voltage VCP-WG Generator Vacuum Circuit Breakers handle high continuous current levels, fault conditions, and various voltage conditions. They operate up to 3000 A with natural air convection cooling, and up to 4500 A with suitable enclosure fan cooling. Circuit breakers can perform under out-of-phase conditions when generator and power system voltages are not in sync.

Vacuum Circuit Breakers replace air magnetic units.

VR-Series medium voltage vacuum replacement (MVVR) breakers are functional electrical and mechanical replacements for air magnetic circuit breakers. Four times faster and 16 times more powerful than air magnetic breakers, they have SureClose(TM) MOC system that prevents stalling and damage to cell and MOC switch. Breakers are reversible, if cell structure modifications are necessary, and only...
