1SDA072306R1 ABB E2.2N 1250 Ekip Touch LSIG 3p WMP Air Circuit Breaker

Why Choose the ABB E2.2N 1250 Ekip Touch LSIG 3p WMP Air Circuit Breaker?

The ABB E2.2N 1250 Ekip Touch LSIG 3p WMP, order code 1SDA072306R1, is a SACE Emax 2 air circuit breaker moving part designed for advanced protection, switching and control in low-voltage AC power distribution systems. This three-pole E2.2N model combines a rated uninterrupted current of 1250 A with ABB's Ekip Touch LSIG solid-state electronic protection release.

The Ekip Touch LSIG trip unit provides long-time overload, short-time delayed short-circuit, instantaneous short-circuit and earth-fault protection. Its touchscreen interface supports intuitive configuration and access to protection, measurement and operating information, while the LSIG architecture provides comprehensive protection for demanding distribution networks.

This version is supplied as a withdrawable moving part (WMP) for use with the corresponding Emax 2 fixed chassis. It is rated for 690 V AC and provides an ultimate short-circuit breaking capacity of 66 kA at 400 V AC, 50 Hz, making it suitable for substantial industrial, commercial and infrastructure power-distribution duties.
