1SDA072883R1 ABB E2.2S 800 Ekip Dip LSIG 4p WMP Air Circuit Breaker

Why Choose the ABB E2.2S 800 Ekip Dip LSIG 4p WMP Air Circuit Breaker?

The ABB E2.2S 800 Ekip Dip LSIG 4p WMP, order code 1SDA072883R1, is a high-performance four-pole withdrawable air circuit breaker moving part designed for protection and switching in demanding low-voltage power distribution systems. Part of the ABB SACE Emax 2 E2.2 series, it combines an 800 A rated current with an Ekip Dip LSIG solid-state electronic trip unit for comprehensive overload, selective short-circuit, instantaneous short-circuit and earth-fault protection.

The Ekip Dip LSIG trip unit provides long-time overload, short-time delayed short-circuit, instantaneous short-circuit and earth-fault protection. Its electronic protection architecture provides adjustable settings through DIP switches, supporting effective coordination of upstream and downstream protective devices while helping safeguard conductors, switchgear and connected equipment.

The E2.2S performance level provides an ultimate short-circuit breaking capacity of 85 kA at 440 V AC and a rated short-time withstand current of 66 kA for 1 s. Its four-pole withdrawable construction allows the moving breaker to be separated from the corresponding fixed part for inspection and servicing, making it well suited to maintainable high-performance switchboard installations.

Comprehensive LSIG Protection for Low-Voltage Distribution

The ABB Ekip Dip LSIG release combines four key protection functions in a practical electronic trip unit. Long-time protection responds to sustained overloads, short-time protection supports selective coordination between protective devices, instantaneous protection provides rapid interruption of severe short circuits, and earth-fault protection helps detect potentially damaging fault currents to earth.

The E2.2S platform combines this comprehensive electronic protection with substantial fault-current performance, including an 85 kA breaking capacity at 440 V AC. Its withdrawable construction enables the moving breaker to be removed from the corresponding fixed part for servicing, supporting switchboards where maintainability, selective coordination and continuity of electrical service are important.
