ABB 1SDA071191R1 E4.2N 4000 Ekip Dip LI 3p F HR

The ABB 1SDA071191R1 is an industrial air circuit breaker configured with a three‑pole arrangement and an Ekip Dip LI trip unit. This ACB circuit breaker is designed to provide main protection and switching in low voltage air circuit breaker applications where coordinated thermal‑magnetic and electronic trip functions are required. As an ABB air circuit breaker, it integrates the trip unit functionality directly with the breaker frame to manage overload, short‑circuit and protection settings through the Ekip Dip LI interface.

This low voltage air circuit breaker is intended for use in switchgear and distribution panels that require a compact, removable protection device with adjustable trip characteristics. The 3‑pole configuration makes it suitable for three‑phase distribution systems, and the Ekip Dip LI trip unit provides configurable protection and diagnostic capabilities for system coordination and selective tripping. Installers and electrical engineers select this type of ACB circuit breaker where coordinated protection, clear trip logic and straightforward integration into distribution layouts are priorities.
