Withdrawable generator circuit-breaker with truck-type design

Rated nominal current up to 5,400 A
The perfect solution for multiple paralleled generator and/or feeder systems
High level of availability and protection of people with LSC 2B loss of service continuity category

Withdrawable GCB truck-type design for applications up to 110 MW
The VB1-D ensures high plant availability with its loss of service continuity category LSC 2B (separate partitions for busbar, connection, and switching-device compartments). Along with its digitalization options, The VB1-D generator switchgear has an expandable modular concept rated for application up to 5,400 A and short circuit ratings up to 72 kA, making it ideally suited for industries, oil & gas and distributed power applications. These features make it especially attractive for power plants with multiple generators or auxiliary feeders for in-house use, excitation or break disconnectors. Because they require a great deal of switching capability and available space, they are often used in hydroelectric power plants and retrofit projects.
