DESCRIBE

The ABB E3N3200 PR121/P‑LSIG 4‑pole WHR Air Circuit Breaker is a high‑capacity low‑voltage protective device from ABB’s SACE Emax E3N series designed for three‑phase power distribution systems. It incorporates a PR121/P‑LSIG electronic trip unit that provides adjustable protection against overload, short‑time, instantaneous, and ground fault conditions. The breaker’s withdrawable horizontal rear (WHR) configuration allows it to be easily removed from switchgear frames for maintenance or service without disconnecting main busbars. This type of circuit breaker is suited for use as a main distribution breaker or feeder protection in industrial and commercial switchgear.
