1SDA072982R1 ABB E2.2S 1600 Ekip Dip LSI 4P WMP Air Circuit Breaker

Why Choose the ABB E2.2S 1600 Ekip Dip LSI 4p WMP Air Circuit Breaker?

The ABB E2.2S 1600 Ekip Dip LSI 4p WMP, order code 1SDA072982R1, is a high-performance four-pole withdrawable air circuit breaker moving part from the ABB SACE Emax 2 range. Rated at 1600 A, it is engineered for demanding low-voltage power distribution systems and incorporates the dependable Ekip Dip LSI solid-state electronic trip unit.

The Ekip Dip LSI release provides long-time (L), selective short-time (S) and instantaneous (I) protection. This combination protects against overloads and different levels of short-circuit fault while the selective short-time function supports coordinated operation between upstream and downstream protective devices, helping isolate faults without unnecessarily disconnecting unaffected parts of the installation.

The E2.2S performance level combines a rated ultimate short-circuit breaking capacity of 85 kA at 400–440 V AC with a rated short-time withstand current of 66 kA for 1 s. Its withdrawable moving-part construction is designed for the corresponding Emax 2 fixed part, supporting efficient inspection, servicing and replacement in industrial and commercial switchboards.

Reliable Selective Protection for High-Current Distribution

The ABB SACE Emax 2 platform is designed to protect high-current low-voltage electrical systems against potentially damaging overload and short-circuit conditions. The Ekip Dip LSI release combines long-time overload, selective short-time and instantaneous protection, enabling the breaker to respond appropriately to different fault conditions while protecting conductors, switchgear, transformers and connected equipment.

The selective short-time function is particularly useful in distribution systems containing multiple levels of protective devices, where coordinated fault clearing can improve continuity of supply. Combined with the E2.2S frame's 85 kA breaking performance and service-friendly withdrawable architecture, the 1SDA072982R1 provides dependable protection for demanding industrial, commercial and infrastructure switchboards.

Typical Applications

• Low-voltage main distribution switchboards.
• Industrial power distribution systems.
• Transformer secondary distribution and protection.
• Commercial and infrastructure electrical distribution.
• Manufacturing and process plant switchgear.
• High-current feeder and incomer protection.
• Selective distribution networks requiring coordinated short-circuit protection.
• Four-wire low-voltage distribution systems.
