The ABB SACE E2.2N 3‑pole Air Circuit Breaker is a low‑voltage protective device in ABB’s Emax 2 E2.2N series designed for industrial and commercial power distribution applications. It provides reliable protection for three‑phase electrical circuits by interrupting current under overload, short‑circuit, instantaneous and ground‑fault conditions when equipped with the appropriate electronic trip unit. The breaker can be configured in fixed or withdrawable forms and supports a variety of electronic protection modules (such as Dip LI, LSIG, Touch LSIG, etc.) to suit different network coordination requirements. These breakers are typically installed as main or feeder protection elements in switchgear, power panels, and distribution boards.
