ABB 1SDA071701R1 E2.2S 2500 Ekip Dip LI 4p F HR

This ABB 1SDA071701R1 is an air circuit breaker configured with the E2.2S designation and an Ekip Dip LI trip unit. As an air circuit breaker, it provides mechanical switching and electrical protection in low-voltage distribution systems using air as the arc quenching medium. The assembled combination of the E2.2S platform and the Ekip Dip LI trip unit defines the breaker’s protection and control interface for overcurrent and switching duties.

This ACB circuit breaker is intended for installation in low voltage switchgear and distribution boards where a controlled, selectable trip characteristic is required. In industrial environments an ABB air circuit breaker is typically chosen to perform incoming main protection, sectioning of busbars, or protection of large feeder circuits because it combines a robust air-interruption mechanism with a programmable trip unit. The presence of the Ekip Dip LI trip unit indicates integrated electronic trip functionality suited to coordinated protection schemes in industrial air circuit breaker applications.
