1SDA072253R1 ABB E2.2S 800 Ekip Dip LSIG 3p WMP Air Circuit Breaker

Why Choose the ABB E2.2S 800 Ekip Dip LSIG 3p WMP Air Circuit Breaker?

The ABB E2.2S 800 Ekip Dip LSIG 3p WMP, order code 1SDA072253R1, 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 E2.2S frame with an Ekip Dip LSIG solid-state electronic trip unit for comprehensive protection in demanding low-voltage power distribution systems.

The Ekip Dip LSIG release provides long-time overload, short-time delayed short-circuit, instantaneous short-circuit and ground-fault protection. DIP-switch configuration provides a straightforward method of setting the principal protection parameters without requiring a touchscreen interface, making the breaker well suited to conventional industrial and infrastructure distribution applications.

The E2.2S performance class provides a rated ultimate short-circuit breaking capacity of 85 kA at 440 V AC together with a rated short-time withstand current of 66 kA for 1 s. Its withdrawable moving-part construction supports convenient inspection, replacement and maintenance within compatible Emax 2 switchgear.
