ABB 1SDA071581R1 E2.2N 1250 Ekip Dip LI 4p F HR

The ABB 1SDA071581R1 is an air circuit breaker configured as E2.2N with a rated current marking of 1250 and a factory-designated trip unit labeled Ekip Dip LI in a 4-pole arrangement. This entry provides the precise model identification and key nameplate references so specifiers and maintenance teams can confirm compatibility with existing switchgear and single-line diagrams. As an air circuit breaker and ACB circuit breaker, this unit uses air as the interrupting medium and is intended for low-voltage distribution applications.

This low voltage air circuit breaker is used in distribution panels and withdrawable or fixed switchgear where four-pole protection and a digital/mechanical trip interface (Ekip Dip LI) are required. An industrial air circuit breaker of this model is typically applied where centralised protection, selective coordination, and clear trip settings are required for main feeds, feeders serving critical loads, or for selective upstream protection of distribution transformers. The product title and trip designation provide the exact reference needed for procurement, panel integration, and engineering documentation.

• Brand: ABB
