1SDA073032R1 ABB E2.2H 2000 Ekip Dip LSI 4p WMP Air Circuit Breaker 2000 A

Why Choose the ABB E2.2H 2000 Ekip Dip LSI 4p WMP Air Circuit Breaker?

The ABB E2.2H 2000 Ekip Dip LSI 4p WMP, order code 1SDA073032R1, is a high-performance four-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for protection and switching in demanding low-voltage power distribution systems. With a rated uninterrupted current of 2000 A, it provides dependable protection for high-current industrial, commercial and infrastructure installations.

This E2.2H breaker is equipped with an Ekip Dip LSI solid-state electronic trip unit, providing long-time overload (L), short-time short-circuit (S) and instantaneous short-circuit (I) protection. The additional short-time protection function supports selective coordination between upstream and downstream protective devices, helping isolate faults while maintaining continuity elsewhere in the electrical distribution system.

The H performance level provides a rated ultimate short-circuit breaking capacity of 100 kA at 400 V AC, while the breaker is suitable for systems rated up to 690 V AC. Its four-pole withdrawable WMP construction enables the moving part to be withdrawn from the separate chassis, supporting efficient inspection, maintenance and replacement in critical switchboard installations.

Reliable Selective Protection for Low-Voltage Power Distribution

Air circuit breakers such as the ABB E2.2H protect high-current electrical distribution circuits against potentially damaging overload and short-circuit conditions. The Ekip Dip LSI release continuously monitors circuit current and provides long-time, short-time and instantaneous protection functions, enabling the breaker to respond appropriately to different types and magnitudes of overcurrent.

The short-time protection function is particularly valuable in distribution systems where selective coordination is required. Combined with the withdrawable Emax 2 construction, the E2.2H provides a robust and service-friendly solution for switchboards where high fault-breaking capability, system availability and maintainability are important.

Typical Applications

• Main incoming protection for low-voltage switchboards.
• Industrial power distribution systems.
• High-current feeder and distribution protection.
• Manufacturing and process plants.
• Commercial and large-building electrical distribution.
• Data centres and critical infrastructure.
• Utility and infrastructure distribution panels.
• Generator and transformer distribution systems.
