1SDA072369R1 ABB E2.2H 1600 Ekip Hi-Touch LSIG 3p WMP Air Circuit Breaker

Why Choose the ABB E2.2H 1600 Ekip Hi-Touch LSIG 3p WMP Air Circuit Breaker?

The ABB E2.2H 1600 Ekip Hi-Touch LSIG 3p WMP, order code 1SDA072369R1, is a high-performance SACE Emax 2 air circuit breaker designed for advanced protection and switching in demanding low-voltage power distribution systems. Part of the ABB Emax 2 E2.2 series, this three-pole withdrawable moving part combines a 1600 A rated current with the advanced Ekip Hi-Touch LSIG solid-state electronic protection release.

Designed for critical industrial, commercial and infrastructure installations, the E2.2H provides comprehensive protection against overload, short-circuit and earth-fault conditions. Its Ekip Hi-Touch LSIG release provides long-time, short-time, instantaneous and ground-fault protection functions together with advanced measurement, monitoring and power-management capabilities.

With a rated operational voltage of 690 V AC and an ultimate short-circuit breaking capacity of up to 100 kA at 400–440 V AC, the E2.2H 1600 is engineered for installations with high prospective fault currents. Its withdrawable moving-part construction supports efficient inspection, servicing and replacement within compatible ABB Emax 2 switchgear.
