Electrically operated vacuum contacts for frequent operation without the slamming forces of spring energy mechanisms.

Eliminate the asbestos containing arc chutes.

Contact arcing is contained within vacuum bottles.

Mechanical interlocks and electrical controls to mate with existing switchgear.

Electrically operated vacuum contacts for faster breaker opening and closing times used in arc flash energy calculations.

Integral undervoltage protection that can be enabled or disabled for motor or feeder applications via a selector switch.

Exchange one breaker at a time during scheduled motor circuit maintenance outages.

The original air circuit breaker will be provided by the customer.  The primary bushings from the original air breakers and control connectors that mate with the existing switchgear cell will be reconditioned and re-used.
