ABB 1SDA073912R1 E2.2 W FP Iu=2500 4p HR HR

This listing is for the ABB 1SDA073912R1 air circuit breaker, an industrial air circuit breaker designed and branded by ABB. The model designation and markings identify the unit as a 4-pole ACB with Iu=2500 and the E2.2 W FP trip arrangement. As an air circuit breaker, this device provides a means to switch and protect low-voltage power systems by interrupting fault currents in the air medium.

The ABB 1SDA073912R1 is intended for use in low-voltage power distribution and factory switchgear where multi-pole protection and selectable trip characteristics are required. Typical locations include main incoming feeders, distribution bus sections, and industrial power panels that require an ACB circuit breaker with a fixed trip unit designation E2.2 W FP. Engineers and electricians select this ABB air circuit breaker when a compact, multi-pole protective device is specified for distribution-level protection within switchgear assemblies.
