1SDA073046R1 ABB E2.2N 2500 Ekip Touch LSIG 4p WMP Air Circuit Breaker

Why Choose the ABB E2.2N 2500 Ekip Touch LSIG 4p WMP Air Circuit Breaker?

The ABB E2.2N 2500 Ekip Touch LSIG 4p WMP, order code 1SDA073046R1, is a high-performance four-pole air circuit breaker moving part designed for low-voltage power distribution, protection and control. As part of the advanced ABB SACE Emax 2 series, it combines a 2500 A current rating with the intelligent Ekip Touch LSIG electronic trip unit for comprehensive electrical protection.

The Ekip Touch LSIG trip unit provides long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection. Its touchscreen interface supports straightforward protection configuration and monitoring, making the breaker suitable for demanding industrial, commercial and infrastructure power distribution systems where selective and dependable protection is essential.

This E2.2N configuration has a 2500 A rated uninterrupted current, four-pole construction and a rated operational voltage up to 690 V AC. The withdrawable moving-part design simplifies inspection, servicing and replacement within compatible SACE Emax 2 fixed parts, while the N performance level provides a rated ultimate short-circuit breaking capacity of 66 kA at 400/415 V AC.

Advanced Power Protection with Ekip Touch LSIG

The ABB Ekip Touch LSIG release continuously supervises electrical conditions and provides adjustable protection against overloads and multiple types of short-circuit fault. The additional earth-fault protection function helps protect distribution systems against potentially damaging ground-fault currents, while the touchscreen interface makes protection settings and operating information readily accessible.

SACE Emax 2 circuit breakers are engineered for low-voltage power distribution applications requiring high levels of reliability, selectivity and system protection. The withdrawable construction allows the breaker moving part to be disconnected from the fixed section of the switchgear, supporting efficient maintenance and helping minimise disruption during servicing.

Typical Applications

• Industrial low-voltage power distribution switchboards.
• Main incoming and outgoing feeder protection.
• Commercial buildings and large infrastructure installations.
• Manufacturing plants and process facilities.
• Data centres and critical power distribution systems.
• Generator and transformer distribution protection.
• Utility and energy distribution installations.
• High-current electrical distribution panels requiring earth-fault protection.
