At 17.5 kV, VAH can switch:
• a rated short-circuit breaking current of 63 kA
• rated currents up to 8,000 A
The extremely robust and "open" construction design allows air cooling of the pole sections.
This permits increased ratings for high mechanical and electrical switching cycles, high insulation level and high normal currents.
Schneider Electric`s VAH circuit breaker meets the requirements of the latest IEEE C37.013 standards.
It has been referenced and installed in industrial processes all over the world.
Whether for power plants or generator switchboards, you need a flexible yet robust circuit breaker for high mechanical and electrical switching applications.
Perfect for modernization and extension
Since Schneider Electric was one of the first to develop and manufacture circuit breakers with vacuum interrupters, our expertise in this field allows us to complete the VAH product range with a high performance indoor generator circuit
breaker.
This VAH vacuum circuit breaker with rated short circuit currents up to 63 kA has been specifically developed to face high mechanical and electrical switching applications. VAH is also an ideal circuit breaker solution for OEMs dealing
with power generation projects.
These circuit breakers are designed for rated voltages up to 17.5 kV and for a rated peak lightning withstand voltage of 110 kV. The VAH circuit breakers are flexible for fixed mounted installation or on withdrawable trucks. They are
particularly suited for modernizing or extending existing systems.
