The ABB E1.2B 1250 Ekip Dip LI 3‑Pole Air Circuit Breaker is a heavy‑duty low‑voltage protective device from ABB’s SACE Emax 2 E1.2B series designed for three‑phase industrial and commercial power distribution systems. It incorporates an Ekip DIP electronic trip unit with LI protection, providing adjustable long‑time and instantaneous overcurrent protection. This breaker model is typically supplied in a withdrawable (WMP) version, allowing the unit to be easily inserted or removed from switchgear for maintenance without disconnecting the main busbars. It is suitable as main distribution or feeder protection in electrical panels, switchgear, and distribution boards.
