  • Power/Vac

    Power/Vac® circuit breakers : The new Power/Vac series of circuit breakers have been tested to the latest ANSI C37.06-2009 standard. They are UL listed and KEMA certified test reports are available. This latest design is based on the proven ML-17 mechanism, which has been in use for more than  35 years. The reliability of Power/Vac has been demonstrated by its ability to handle 63kA high interrupting duty for nearly 20 years. Adding to our flexibility of design, all breaker ratings are now available with 5 cycle or 3 cycle interrupting times. Class C2 (formerly classified as definite purpose) capacitor switching capability is also now available, which incorporates faster TRV values than in previous edition of the ANSI standards.
