ABB 1SDA073911R1 E2.2 W FP Iu=2500 3p HR HR

This ABB 1SDA073911R1 is an air circuit breaker configured for three‑phase low‑voltage power distribution. The model designation and series information (E2.2 W FP) identify it as a factory‑specified ABB air circuit breaker intended for use where a 3‑pole switching device with a 2500 rated current (Iu=2500) is required. As an ACB circuit breaker, it provides switching and overcurrent interruption functions in industrial and commercial power systems.

In practical installations this low voltage air circuit breaker is installed as a main incoming or distribution feeder device inside switchgear and distribution panels. The ABB air circuit breaker form factor and three‑pole arrangement make it suitable for three‑phase systems that require robust continuous current handling and coordinated protection strategies. Project engineers and panel builders select this industrial air circuit breaker when the installation calls for a high‑current three‑pole breaker from a known OEM with the specific model and series listed.
