ABB 1SDA072131R1 E1.2B 1000 Ekip Dip LI 3p WMP

The ABB 1SDA072131R1 is an air circuit breaker designed for low-voltage distribution panels and switchgear where a robust, configurable protection element is required. This ACB circuit breaker incorporates the Ekip Dip LI trip unit and a three-pole configuration, providing coordinated protection and selective tripping in three-phase systems. As an industrial air circuit breaker, it is intended to serve as the primary switching and protective device for feeders and bus sections in commercial and industrial installations.

This ABB air circuit breaker is used in low-voltage air circuit breaker applications such as mains distribution, motor feeder protection, and busbar sectioning inside fixed or withdrawable switchgear. An ACB circuit breaker with an Ekip Dip LI trip unit is chosen when adjustable, electronically managed overload and short‑circuit protection is needed together with clear diagnostic and trip characteristics. The product is suitable where users require a dedicated industrial air circuit breaker with the control and protection features associated with the Ekip Dip LI platform.
