MV vacuum interrupters and embedded poles

The core component for your switching application

With more than 30 years of experience and continuous innovation, Vacuum Interrupters and Embedded Poles from ABB are proven in thousands of applications and manufactured according to latest quality standards. A standardized portfolio and full global supplier risk management allows shortest lead times.

Vacuum switching technology is the dominant switching principle in medium voltage.
Together with perfect function at the selected ratings, the compactness of these components is especially decisive, as they determine the overall size of the whole switching device. Embedding the vacuum interrupters in a special cast resin makes the pole parts of the circuit-breaker notably robust and at the same time protects the ABB vacuum interrupters from impact, dust, moisture and external damage. There is currently no more effective form of protection.
