1SDA072395R1 ABB E2.2S 2000 Ekip Touch LSI 3p WMP Air Circuit Breaker

Why Choose the ABB E2.2S 2000 Ekip Touch LSI 3p WMP Air Circuit Breaker?

The ABB E2.2S 2000 Ekip Touch LSI 3p WMP, order code 1SDA072395R1, is a high-performance air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for reliable protection and control of demanding low-voltage electrical distribution systems. Combining the E2.2S frame with a 2000 A rated uninterrupted current and Ekip Touch LSI electronic trip unit, it provides advanced overload and short-circuit protection for industrial, commercial and infrastructure power networks.

The Ekip Touch LSI electronic trip unit provides long-time overload, short-time delayed short-circuit and instantaneous short-circuit protection. Its touchscreen interface supports convenient configuration and access to operating information, while the short-time protection function enables selective coordination between upstream and downstream protective devices.

The E2.2S performance level provides a rated ultimate short-circuit breaking capacity of 85 kA at 440 V AC together with a rated short-time withstand current of 66 kA for 1 s. This three-pole WMP configuration is supplied as a withdrawable moving part, supporting efficient inspection, servicing and replacement within compatible ABB Emax 2 withdrawable switchgear assemblies.

Selective LSI Protection for High-Current Power Distribution

ABB SACE Emax 2 air circuit breakers are engineered for the protection and control of low-voltage electrical networks where high current capacity, dependable fault interruption and selective coordination are required. The E2.2S performance level combines a 2000 A current rating with substantial short-circuit breaking and withstand capability, making this breaker suitable for main distribution boards, industrial switchgear and critical power-distribution installations.

The Ekip Touch LSI trip unit combines long-time overload protection with short-time delayed and instantaneous short-circuit protection. The short-time function supports selective coordination by allowing downstream protective devices an opportunity to clear local faults before an upstream breaker operates, while instantaneous protection provides rapid interruption of severe short-circuit conditions.

Typical Applications

• Low-voltage main distribution switchboards.
• Industrial power distribution systems.
• Main incoming electrical supplies.
• Manufacturing and process plants.
• Commercial building electrical distribution.
• Infrastructure and utility installations.
• Electrical systems requiring high-current selective LSI protection.
