DESCRIBE

The ABB E2N1600 PR122/P‑LSIG 3‑pole WHR Air Circuit Breaker is a high‑capacity low‑voltage protective device from ABB’s SACE Emax E2N series designed for industrial and commercial three‑phase power distribution systems. It integrates a PR122/P‑LSIG electronic trip unit that provides adjustable overcurrent protection including long‑time, short‑time, instantaneous and ground fault functions. The breaker is in a withdrawable (WHR) configuration, which allows the unit to be safely removed from the switchgear frame for maintenance or testing without disconnecting the main busbars. This breaker is suitable as a main distribution or feeder protection breaker in electrical panels and switchboards requiring robust protection and high performance.
