Why Choose the ABB E2.2S 1600 Ekip Dip LI 4p WMP Air Circuit Breaker?
The ABB E2.2S 1600 Ekip Dip LI 4p WMP, order code 1SDA072981R1, is a high-performance four-pole withdrawable air circuit breaker moving part from the ABB SACE Emax 2 range. Rated at 1600 A, it is designed for demanding low-voltage power distribution applications and incorporates the reliable Ekip Dip LI solid-state electronic trip unit.
The Ekip Dip LI release provides long-time (L) overload and instantaneous (I) short-circuit protection. The overload setting can be adjusted across 640–1600 A, while instantaneous protection is adjustable from 2400–24000 A, providing straightforward electronic protection for feeders, incomers, transformers and other high-current circuits.
The E2.2S performance level delivers an ultimate short-circuit breaking capacity of 85 kA at 400–440 V AC and 66 kA at 500–690 V AC. Its withdrawable moving-part construction connects through a separate fixed chassis, simplifying inspection, maintenance and breaker replacement within compatible Emax 2 switchboards.
