ABB 1SDA070821R1 E1.2B 1250 Ekip Dip LI 3p F F Air Circuit Breakers

ABB 1SDA070821R1 Air Circuit Breaker – E1.2B 1250, 3‑pole, Ekip Dip LI

This ABB air circuit breaker is the 1SDA070821R1 model from the E1.2B family fitted with an Ekip Dip LI trip unit in a three‑pole configuration. As an ACB circuit breaker designed for low‑voltage distribution, it provides overcurrent and short‑circuit interruption functions tailored for three‑phase systems. The device form and integrated Ekip Dip LI protection make it suitable for installation inside distribution panels and modular switchgear where coordinated protection characteristics are required.

In low‑voltage power distribution the ABB air circuit breaker is used to protect distribution feeders, motor circuits and panelboards against fault currents while enabling selective coordination within an electrical system. System integrators, panel builders and maintenance teams specify this industrial air circuit breaker where predictable trip behaviour and repeatable interruption performance are needed in manufacturing, process and commercial installations. The Ekip Dip LI trip unit provides the defined protective functions embedded in the breaker, which is why this ACB circuit breaker is selected for switchgear assemblies that require consistent protection settings and straightforward integration with ABB protection philosophies.
