1SDA073070R1 ABB E2.2H 2500 Ekip G Hi-Touch LSIG 4p WMP Air Circuit Breaker

Why Choose the ABB E2.2H 2500 Ekip G Hi-Touch LSIG 4p WMP Air Circuit Breaker?

The ABB E2.2H 2500 Ekip G Hi-Touch LSIG 4p WMP, order code 1SDA073070R1, is a high-performance four-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for advanced protection, control and monitoring of demanding low-voltage power distribution and generator systems. Rated at 2500 A, this withdrawable moving part combines the high-breaking-capacity E2.2H platform with the advanced Ekip G Hi-Touch LSIG electronic trip unit.

The Ekip G Hi-Touch LSIG release provides long-time overload (L), short-time selective short-circuit (S), instantaneous short-circuit (I) and earth-fault (G) protection. Developed for sophisticated power distribution and generator applications, the G Hi-Touch platform combines advanced protection functions with measurement, monitoring and an intuitive touchscreen interface.

The E2.2H performance level is engineered for electrical networks with high prospective fault currents, providing a rated ultimate short-circuit breaking capacity of 100 kA at 380–440 V AC and 85 kA at 500–690 V AC. Its 2500 A rating, four-pole configuration and withdrawable moving-part construction make it particularly suitable for main switchboards, generator installations and critical power distribution systems requiring high breaking performance and serviceability.
