ABB 1SDA073907R1 Air Circuit Breaker – 1600 A, 3‑pole

The ABB 1SDA073907R1 is a 3‑pole air circuit breaker designed for low‑voltage power distribution. This specific ACB circuit breaker is supplied in the ABB E1.2 W FP configuration and is identified by SKU 1SDA073907R1 with a rated current of 1600 A. As an industrial air circuit breaker, it performs the core function of interrupting fault and overload currents in a three‑phase system while providing a clear, compact device identity for installation and maintenance records.

This ABB air circuit breaker is used in low voltage air circuit breaker applications inside switchgear and power distribution assemblies where a 3‑pole protective device with a 1600 A rating is required. Engineers and technicians select an ACB circuit breaker like this one when specification calls for a serviceable, front‑access breaker that integrates into distribution panels and cubicles. The model designation and trip marking make it straightforward to confirm compatibility with switchgear layouts and protection coordination studies.
