ABB 1SDA071201R1 E4.2S 4000 Ekip Dip LI 3p F HR

This ABB 1SDA071201R1 is an air circuit breaker configured as E4.2S 4000 with a three‑pole arrangement and the Ekip Dip LI trip unit. As an industrial air circuit breaker and ACB circuit breaker, it is a factory‑configured protection device designed to interrupt and isolate low‑voltage power circuits. The model designation identifies the exact unit and trip electronics included, so buyers can confirm compatibility with existing switchgear and protection schemes.

In low‑voltage power distribution the ABB air circuit breaker is used where selective circuit protection, fault interruption and manual or automatic switching are required. Typical installations include main distribution panels, switchgear line‑ups and power distribution sections that require an ACB circuit breaker with the specified E4.2S 4000 configuration and Ekip Dip LI trip unit. Engineers select this type of low voltage air circuit breaker when they need a dedicated, modular breaker element that integrates with panel control and protection systems.
