1SDA072996R1 ABB E2.2H 1600 Ekip Touch LSIG 4P WMP Air Circuit Breaker

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

The ABB E2.2H 1600 Ekip Touch LSIG 4p WMP, order code 1SDA072996R1, 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 LSIG electronic trip unit for demanding low-voltage power distribution systems.

The Ekip Touch LSIG release provides comprehensive long-time (L), selective short-time (S), instantaneous (I) and earth-fault (G) protection. Its electronic protection platform enables adjustable fault protection and selective coordination, helping protect conductors, transformers, switchgear and connected equipment while reducing unnecessary interruption to unaffected sections of the electrical network.

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. Combined with high short-time withstand capability and withdrawable construction, the 1SDA072996R1 is well suited to high-fault-level switchboards requiring comprehensive LSIG protection and efficient maintenance.
