1SDA072906R1 ABB E2.2N 1000 Ekip Touch LSIG 4P WMP Air Circuit Breaker

Why Choose the ABB E2.2N 1000 Ekip Touch LSIG 4p WMP Air Circuit Breaker?

The ABB E2.2N 1000 Ekip Touch LSIG 4p WMP, order code 1SDA072906R1, is a high-performance four-pole air circuit breaker moving part from the ABB SACE Emax 2 range. Designed for demanding low-voltage power distribution, transformer and installation protection, it combines a 1000 A rated uninterrupted current with the advanced Ekip Touch LSIG electronic trip unit.

The Ekip Touch LSIG release provides comprehensive long-time (L), selective short-time (S), instantaneous (I) and earth-fault (G) protection. This combination allows the breaker to protect against overloads, short circuits and earth faults while supporting selective coordination with downstream protective devices, helping improve both equipment protection and continuity of supply.

The E2.2N frame provides an ultimate short-circuit breaking capacity of 66 kA across its specified AC operating-voltage range up to 690 V AC. Its withdrawable moving-part construction supports efficient switchboard maintenance, while the four-pole arrangement incorporates a neutral pole rated at 100% of the rated uninterrupted current.
