1SDA071162R1 ABB E4.2H 3200 Ekip Dip LSI 3p F HR Air Circuit Breaker

Why Choose the ABB E4.2H 3200 Ekip Dip LSI 3p F HR Air Circuit Breaker?

The ABB E4.2H 3200 Ekip Dip LSI 3p F HR, order code 1SDA071162R1, is a high-performance Emax 2 air circuit breaker (ACB) designed for reliable protection and switching in demanding low-voltage electrical distribution systems. As part of the ABB SACE Emax 2 series, it combines a 3200 A current rating with high short-circuit performance for industrial, infrastructure and critical power applications.

This fixed three-pole circuit breaker incorporates the Ekip Dip LSI solid-state electronic trip unit, providing long-time overload, selective short-time and instantaneous short-circuit protection. The Ekip Dip interface uses straightforward DIP-switch settings, allowing essential protection parameters to be configured locally while supporting effective selectivity and coordination within electrical distribution systems.

With a rated uninterrupted current of 3200 A, a rated operational voltage of up to 690 V AC and an ultimate short-circuit breaking capacity of 100 kA at 440 V AC, the E4.2H is engineered for installations with substantial prospective fault currents. Its fixed three-pole construction and rear horizontal terminals make it suitable for integration into high-current low-voltage switchboards.
