DESCRIBE

The ABB E1.2C 1600 A 3‑pole Air Circuit Breaker is a low‑voltage protective device from ABB’s SACE Emax 2 E1.2C series, designed for industrial and commercial power distribution applications. It provides reliable protection for three‑phase circuits against overload and short‑circuit faults when equipped with an appropriate trip unit such as Ekip Touch LI, Ekip Touch LSIG, Ekip Dip LI, or Ekip Dip LSIG. This fixed‑mount breaker is suitable as a main distribution breaker or feeder protection device in switchgear, distribution panels, and electrical installations operating up to ~690 V AC. It also typically includes auxiliary contacts and status indications for breaker position and signaling.
