1SDA072995R1 ABB E2.2H 1600 Ekip Touch LSI 4P WMP Air Circuit Breaker

Why Choose the ABB E2.2H 1600 Ekip Touch LSI 4p WMP Air Circuit Breaker?

The ABB E2.2H 1600 Ekip Touch LSI 4p WMP, order code 1SDA072995R1, is a high-performance four-pole withdrawable air circuit breaker moving part from the ABB SACE Emax 2 range. Rated at 1600 A, it combines the high-breaking-capacity E2.2H frame with the advanced Ekip Touch LSI solid-state electronic trip unit for demanding low-voltage power distribution.

The Ekip Touch LSI release provides long-time (L), selective short-time (S) and instantaneous (I) protection. This combination protects against overloads and short circuits while supporting selective coordination between upstream and downstream protective devices, helping isolate faults at the appropriate level and improve continuity of supply.

The E2.2H performance level delivers an ultimate short-circuit breaking capacity of 100 kA at 400–440 V AC and 85 kA at 500–690 V AC. Its withdrawable moving-part construction is designed for use with the corresponding Emax 2 fixed part, providing a service-friendly solution for industrial, commercial and infrastructure switchboards.

High-Performance Selective Protection for Critical Distribution

The ABB SACE Emax 2 platform is designed to protect high-current low-voltage electrical systems against potentially damaging overload and short-circuit conditions. The Ekip Touch LSI release combines long-time overload, selective short-time and instantaneous protection, allowing the breaker to respond appropriately to different fault levels while supporting coordinated protection throughout the distribution network.

The E2.2H frame provides particularly high fault-interruption capability, including 100 kA breaking performance at 400–440 V AC and 85 kA short-time withstand capability for 1 s. Combined with its withdrawable architecture and Ekip Touch protection platform, the 1SDA072995R1 is well suited to installations where high fault levels, selectivity, continuity of service and efficient maintenance are key requirements.
