1SDA072352R1 ABB E2.2S 1600 Ekip Dip LSI 3p WMP Air Circuit Breaker

Why Choose the ABB E2.2S 1600 Ekip Dip LSI 3p WMP Air Circuit Breaker?

The ABB E2.2S 1600 Ekip Dip LSI 3p WMP, order code 1SDA072352R1, 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 1600 A rated uninterrupted current and Ekip Dip LSI electronic trip unit, it provides dependable overload and short-circuit protection for industrial, commercial and infrastructure installations.

The Ekip Dip LSI electronic trip unit provides long-time overload, short-time delayed short-circuit and instantaneous short-circuit protection. The addition of short-time protection compared with an LI release supports selective coordination between upstream and downstream protective devices, helping isolate faults close to their source while maintaining continuity of supply to unaffected parts of the electrical network.

The E2.2S performance level provides a rated 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. This three-pole WMP configuration is supplied as the moving part of a withdrawable circuit breaker, enabling convenient inspection, servicing and replacement within compatible ABB Emax 2 withdrawable switchgear assemblies.

Selective LSI Protection for 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 and dependable fault interruption are required. The E2.2S performance level combines a 1600 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 Dip LSI trip unit combines long-time overload protection with short-time delayed and instantaneous short-circuit protection. The short-time function is particularly valuable in selectively coordinated systems, allowing downstream protective devices an opportunity to clear local faults before an upstream breaker operates while still providing rapid protection against 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 selective LSI protection and coordination.
