1SDA072873R1 ABB E2.2N 800 Ekip Dip LSIG 4p WMP Air Circuit Breaker

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

The ABB E2.2N 800 Ekip Dip LSIG 4p WMP, order code 1SDA072873R1, is a 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 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 (L), short-time delayed short-circuit (S), instantaneous short-circuit (I) and earth-fault (G) protection. Its electronic protection architecture and DIP-switch configuration provide straightforward adjustment while supporting selective coordination and comprehensive protection throughout industrial and commercial electrical distribution networks.

The E2.2N performance level provides an ultimate short-circuit breaking capacity of 66 kA at 440 V AC together with a rated short-time withstand current of 66 kA for 1 s. Its four-pole withdrawable construction supports switchboards where high fault-current capability, comprehensive LSIG protection and convenient servicing are required.

Comprehensive LSIG Protection for Low-Voltage Distribution

The ABB Ekip Dip LSIG release combines four essential protection functions within a practical electronic trip unit. Long-time protection responds to sustained overloads, short-time protection supports selective coordination between upstream and downstream devices, instantaneous protection rapidly interrupts severe short circuits, and earth-fault protection helps detect potentially damaging fault currents to earth.

The E2.2N platform combines this comprehensive protection with substantial short-circuit withstand capability. Its withdrawable construction allows the moving breaker to be separated from the corresponding fixed part for inspection and servicing, making it particularly suitable for switchboards where maintainability, selective coordination and continuity of electrical service are important.

• Industrial power distribution systems.
• Commercial building electrical distribution.
• Manufacturing and process facilities.
• Transformer and feeder protection.
• Infrastructure and utility installations.
