1SDA072405R1 ABB E2.2H 2000 Ekip Touch LSI 3p WMP Air Circuit Breaker

Why Choose the ABB E2.2H 2000 Ekip Touch LSI 3p WMP Air Circuit Breaker?

The ABB E2.2H 2000 Ekip Touch LSI 3p WMP, order code 1SDA072405R1, is a high-performance SACE Emax 2 air circuit breaker moving part designed for protection and switching in demanding low-voltage AC power-distribution systems. This three-pole E2.2H model combines a rated current of 2000 A with ABB's Ekip Touch LSI electronic protection release.

The Ekip Touch LSI trip unit provides long-time overload, short-time delayed short-circuit and instantaneous short-circuit protection. Its touchscreen interface supports intuitive configuration and supervision of the protection functions, while the short-time function enables selective coordination with downstream protective devices in complex electrical networks.

Supplied as a withdrawable moving part (WMP), the 1SDA072405R1 is designed for use with the corresponding SACE Emax 2 fixed part. The E2.2H performance level provides an ultimate short-circuit breaking capacity of 100 kA at 400–440 V AC and 85 kA at 500–690 V AC, together with strong short-time withstand performance for demanding high-current switchboards.

Advanced and Selective Protection for High-Current Power Distribution

The ABB SACE Emax 2 E2.2H is engineered for high-current low-voltage distribution systems where strong short-circuit performance and selective electronic protection are required. Its Ekip Touch LSI release combines long-time overload protection with short-time delayed and instantaneous short-circuit functions, enabling engineers to coordinate breaker operation and isolate faults while helping maintain continuity elsewhere in the distribution network.

The E2.2H performance level provides substantial fault-interruption capability, while the withdrawable design improves maintainability by allowing the moving part to be separated from its compatible fixed part for inspection, servicing or replacement. Combined with the Ekip Touch interface, auxiliary contacts and breaker-position indication, the 1SDA072405R1 is well suited to critical high-current switchboards requiring dependable protection and operational flexibility.
