Why Choose the ABB E2.2S 250 Ekip Dip LSIG 4p WMP Air Circuit Breaker?
The ABB E2.2S 250 Ekip Dip LSIG 4p WMP, order code 1SDA073660R1, is a 250 A four-pole withdrawable SACE Emax 2 air circuit breaker moving part designed for protection and switching in low-voltage power distribution systems. It combines the E2.2S performance level with an Ekip Dip LSIG electronic trip unit for comprehensive overcurrent and earth-fault protection.
The fitted Ekip Dip LSIG release provides long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection. This combination supports selective protection strategies while adding dedicated earth-fault detection, making the breaker suitable for distribution systems where coordinated protection and dependable fault interruption are required.
The E2.2S 250 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 enables switching of three phase conductors and the neutral while providing the serviceability advantages of a removable circuit-breaker moving part.

Comprehensive LSIG Protection for Low-Voltage Distribution
The Ekip Dip LSIG electronic release combines four protection functions within one 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 ground-fault protection detects earth-fault conditions requiring dedicated protection.
The E2.2S performance level combines an 85 kA ultimate breaking capacity at 440 V AC with a 66 kA rated short-time withstand current for 1 s. Together with its four-pole withdrawable architecture, ABB 1SDA073660R1 is particularly suitable for switchboards requiring high fault performance, neutral switching, comprehensive LSIG protection and convenient circuit-breaker removal for servicing.
Typical Applications
- Low-voltage main and sub-distribution switchboards.
- Industrial three-phase distribution systems requiring neutral switching.
- Manufacturing and process plant electrical distribution.
- Commercial building and infrastructure power distribution.
- Withdrawable switchgear requiring comprehensive overload, short-circuit and earth-fault protection.
- Distribution systems requiring selective coordination and maintainable circuit-breaker assemblies.
