ABB 1SDA071621R1 E2.2N 1600 Ekip Dip LI 4p F HR

This ABB air circuit breaker is the unit identified by catalog number 1SDA071621R1 and equipped with the Ekip Dip LI trip unit. As an ACB circuit breaker designed and labeled with 4 poles and the 1600 designation, it serves as a selectable protective device for low-voltage distribution systems where a four-pole, electronically configurable trip solution is required. The listing specifies the ABB air circuit breaker model and the exact trip electronics, allowing engineers to match protection logic to a particular installation.

In low-voltage power distribution, this industrial air circuit breaker is used inside switchgear and distribution panels to provide short-circuit and overload protection coordinated with upstream and downstream devices. The presence of the Ekip Dip LI trip unit indicates an electronically controlled protection function set, making this ACB circuit breaker suitable where adjustable protection curves and integral monitoring or trip settings are required. Installers typically place this ABB air circuit breaker in main or feeder positions within modular switchgear assemblies that accept a 4-pole breaker.
