Circuit Breakers - ABB
Circuit breakers protect circuits from overloads and short circuits, and you can reset them after a trip. They're the main overcurrent protection in control panels, switchboards and distribution equipment.
Breaker Types
- Miniature circuit breakers (MCBs) – DIN rail control circuit protection
- Molded case circuit breakers (MCCBs) – higher currents
- Supplementary protectors – equipment protection
- Motor circuit protectors – motor branch circuits
- Ground-fault breakers – personnel protection
Choosing a Breaker
Select current rating, voltage, poles, trip curve and interrupting rating. Confirm UL listing for your application, whether branch circuit (UL 489) or supplementary (UL 1077).
