1SDA071683R1 ABB E2.2H 2000 Ekip Dip LSIG 4P Air Circuit Breaker

Why Choose the ABB E2.2H 2000 Ekip Dip LSIG 4P Air Circuit Breaker?

The ABB 1SDA071683R1 is a high-performance SACE Emax 2 E2.2H air circuit breaker (ACB) rated at 2000 A, designed for protection and switching in demanding low-voltage power distribution systems. As part of the advanced ABB SACE Emax 2 series, this fixed four-pole circuit breaker combines high short-circuit performance with an Ekip Dip LSIG electronic trip unit.

The E2.2H 2000 incorporates the Ekip Dip LSIG solid-state release, providing adjustable protection against overload, selective short circuit, instantaneous short circuit and earth fault conditions. This combination of L, S, I and G protection functions makes the breaker suitable for electrical networks where comprehensive overcurrent and earth-fault protection is required.

With a rated current of 2000 A, a rated operational voltage up to 690 V AC and an ultimate short-circuit breaking capacity of 100 kA at 415 V AC, the E2.2H is engineered for installations with high prospective fault currents. This version is a fixed, four-pole breaker with rear horizontal terminals, enabling integration into industrial and infrastructure low-voltage switchboards.
