1SDA072269R1 ABB E2.2H 800 Ekip Hi-Touch LSIG 3p WMP Air Circuit Breaker

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

The ABB E2.2H 800 Ekip Hi-Touch LSIG 3p WMP, order code 1SDA072269R1, 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 Hi-Touch LSIG electronic trip unit for comprehensive protection, measurement and supervision in demanding low-voltage power distribution systems.

The Ekip Hi-Touch LSIG release provides long-time overload, short-time delayed short-circuit, instantaneous short-circuit and ground-fault protection. Its advanced electronic platform supports sophisticated protection coordination and electrical monitoring, making this breaker suitable for installations where high fault-clearing capability, selectivity and detailed power-system supervision are important.

The E2.2H performance class provides a rated ultimate short-circuit breaking capacity of 100 kA at 400–440 V AC and 85 kA at 500–690 V AC. A rated short-time withstand current of 85 kA for 1 s further supports selective protection schemes, while the withdrawable construction facilitates inspection and maintenance within compatible Emax 2 switchgear.
