- Electrically operated vacuum contacts for frequent operation without the slamming forces of spring energy mechanisms
- No arc chutes and no asbestos.
- Contact arcing is contained within vacuum bottles.
- Mechanical interlocks and electrical controls to mate with existing switchgear.
- Fast fault clearing times reducing arc flash energy
- Exchange one breaker at a time during scheduled motor circuit maintenance outages.
Some steel parts from original breaker truck base will be reused.
