ABB 1SDA071451R1 E1.2B 1250 Ekip Dip LI 4p F F

ABB 1SDA071451R1 Air Circuit Breaker – 1250 A, 4‑pole

This ABB 1SDA071451R1 is an industrial air circuit breaker designed for protection and switching in low-voltage power distribution systems. As an ACB circuit breaker it integrates a factory-fitted Ekip Dip LI trip unit and a four‑pole configuration to provide coordinated overload and short‑circuit protection for three‑phase installations and the associated neutral. The unit is presented as a compact, serviceable device intended for installation where reliable interruption and selective protection are required.

In low-voltage switchgear, a low voltage air circuit breaker like this model is typically used at distribution boards, incoming mains panels, and motor feeder sections where a clear, adjustable trip characteristic is needed. An ABB air circuit breaker with the Ekip Dip LI trip unit is selected when installers and engineers require an electronically controlled trip unit with protection functions suited to industrial distribution—allowing configurable long‑time and short‑time protection and straightforward commissioning within switchgear assemblies.
