The fault conditions near the generator power supply are more harsh than those in the normal distribution circuit. It is necessary to design and develop a special vacuum circuit breaker for protecting the generator considering these special fault characteristics. The VB2 Plus G generator vacuum circuit breaker meets the international double standards of IEC/IEEE 62271-37-01, and has passed the full-set test in the KEMA laboratory.

• The maximum rated current reaches 5000A and the maximum short-circuit breaking capacity reaches 50kA
• The DC component of the system source reaches 75%, and that of the generator source reaches 130%
• The rise rate of the recovery voltage (RRRV) has been verified by KEMA
• It is easy to operate, simple to maintain, and can provide comprehensive protection. It is mainly used in distributed energy, marine gas backup generators, mining power plants, small-sized hydroelectric generators, and small-sized steam turbine generators
