ABB 1SDA071622R1 E2.2N 1600 Ekip Dip LSI 4p F HR

The ABB 1SDA071622R1 is an air circuit breaker configured as a 4‑pole device with a 1600 A rating and an Ekip Dip LSI trip unit. As presented, this unit is an ABB air circuit breaker intended for use where a selectable long‑time, short‑time and instantaneous (LSI) trip characteristic is required. The product designation and fitted trip unit identify it as an ACB circuit breaker designed to provide overcurrent protection and selective interruption in low voltage distribution systems.

This low voltage air circuit breaker is used inside switchgear assemblies and distribution panels where a 4‑pole, 1600 A breaker is specified. An industrial air circuit breaker with an Ekip Dip LSI trip unit is selected in applications that need coordinated overcurrent protection with adjustable long‑time, short‑time and instantaneous settings, and where a dedicated ABB air circuit breaker form factor and control interface are required.
