ABB 1SDA071771R1 E4.2N 3200 Ekip Dip LI 4p F HR

The ABB 1SDA071771R1 is an industrial air circuit breaker configured with an E4.2N platform and an Ekip Dip LI trip unit. This ACB circuit breaker provides mains-level protection in low voltage power distribution systems where coordinated overload, short‑circuit and thermal protection functions are required. As an ABB air circuit breaker, it integrates the trip functionality of the Ekip Dip LI unit with a 4‑pole switching arrangement to manage three phases plus neutral.

This low voltage air circuit breaker is used as a main or feeder device in switchgear and distribution boards that require a compact, removable protection module with adjustable trip capabilities. The combination of the E4.2N frame and Ekip Dip LI trip unit makes this ABB air circuit breaker suitable for installations where selective protection, remote trip signaling and standard protection curves from the trip unit are needed. System designers select this type of ACB circuit breaker when they need a robust, serviceable breaker that interfaces with modular switchgear enclosures.
