Circuit protection from ABB

According to UL 489 and UL 1077

Miniature circuit breakers protect installations against overload and short circuit to ensure reliability and safety for operations. They are selectively switchable, even under load, in the event of a fault or for maintenance purposes. Downtime is minimized, thanks to the devices’ reclining capability.
