ABB 1SDA070951R1 E2.2N 1250 Ekip Dip LI 3p F HR

The ABB 1SDA070951R1 is an industrial air circuit breaker configured with a 3‑pole arrangement and a 1250 A rated current, fitted with the Ekip Dip LI trip unit. This ACB circuit breaker is a modular protection device designed to provide overcurrent and short‑circuit protection within low voltage distribution systems where a compact, serviceable breaker is required. As an ABB air circuit breaker, it integrates the Ekip Dip LI electronics for adjustable protection and local control functions.

In low‑voltage power distribution, this low voltage air circuit breaker is used at main distribution boards, feeder panels, and motor protection switchgear to isolate and protect downstream circuits. The 3‑pole configuration makes it appropriate for three‑phase systems, and the 1250 A rating aligns it with medium-capacity distribution feeders and subfeeders in commercial and light industrial installations. Engineers and installers select this ACB circuit breaker when they need a serviceable, adjustable protection device with the Ekip Dip LI trip unit for onsite tuning and diagnostics.
