ABB 1SDA071772R1 E4.2N 3200 Ekip Dip LSI 4p F HR

The ABB 1SDA071772R1 is an air circuit breaker presented with the designation E4.2N 3200 and the Ekip Dip LSI trip configuration. This ACB circuit breaker is a factory-designated assembly combining ABB hardware and the Ekip Dip LSI trip unit, supplied in a four-pole arrangement. As an industrial air circuit breaker, it is intended for use where robust interruption and adjustable protection are required in low-voltage distribution systems.

In low-voltage power distribution, this ABB air circuit breaker is applied at the point where incoming supply or major distribution feeders require coordinated overload, short‑circuit and protection functions provided by an adjustable trip unit. System designers select an ACB circuit breaker like this one where a compact, withdrawable or fixed air-break device with an Ekip Dip LSI trip profile is needed to provide selective protection and configurable long-time, short-time and instantaneous characteristics. The product designation indicates the installed trip unit and pole configuration, which installers and commissioning engineers use when specifying breakers for switchgear panels.

Applications for this ABB air circuit breaker include main incoming feeders and large distribution feeders in commercial and industrial switchgear where a 4-pole breaker with an Ekip Dip LSI trip unit is specified. Typical scenarios are electrical rooms, distribution boards, and modular switchgear installations requiring adjustable protection settings and coordination with downstream devices. The Ekip Dip LSI trip unit supports coordinated protection strategies for overload, short‑time and instantaneous faults, making this breaker suitable for facilities that need both selective tripping and adjustable fault response.
