1SDA072270R1 ABB E2.2H 800 Ekip G Hi-Touch LSIG 3p WMP Air Circuit Breaker

Why Choose the ABB E2.2H 800 Ekip G Hi-Touch LSIG 3p WMP Air Circuit Breaker?

The ABB E2.2H 800 Ekip G Hi-Touch LSIG 3p WMP, order code 1SDA072270R1, is a high-performance three-pole withdrawable air circuit breaker moving part from the ABB SACE Emax 2 range. Rated at 800 A, it combines the high-breaking-capacity E2.2H frame with an advanced Ekip G Hi-Touch LSIG electronic trip unit for generator protection, power management and demanding low-voltage distribution applications.

The Ekip G Hi-Touch LSIG release provides long-time overload, short-time delayed short-circuit, instantaneous short-circuit and ground-fault protection together with generator-oriented protection and advanced measurement capabilities. This sophisticated protection platform is designed for installations requiring close supervision of generators and electrical networks while supporting selective coordination and reliable fault clearance.

The E2.2H performance class delivers a rated ultimate short-circuit breaking capacity of 100 kA at 440 V AC and a rated short-time withstand current of 85 kA for 1 s. Its withdrawable moving-part construction supports efficient inspection, servicing and replacement within compatible ABB Emax 2 switchgear.
