Safety and reliability solutions for switchgear.

Reduce arc flash energy with HIGH SPEED vacuum circuit breaker replacements from Power Precision that open within 20 ms.

High speed vacuum breakers are built to roll in to vintage switchgear.  Upgrade 1 breaker at a time or all breakers in the lineup on a maintenance outage.

Don't waste money on buying and installing heavy steel arc resistant enclosures.  Use high speed breakers to open faster and reduce arc flash energy.
