1SDA073031R1 ABB E2.2H 2000 Ekip Dip LI 4p WMP Air Circuit Breaker 2000 A

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

The ABB E2.2H 2000 Ekip Dip LI 4p WMP, order code 1SDA073031R1, 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 LI electronic trip unit, providing long-time overload (L) and instantaneous short-circuit (I) protection. The electronic protection architecture enables accurate circuit protection while the Emax 2 platform provides the modularity, maintainability and system integration required in modern low-voltage switchboards.

The H performance level provides a rated ultimate short-circuit breaking capacity of 100 kA at 400 V AC, while the breaker is rated for operation at voltages up to 690 V AC. This four-pole WMP configuration uses ABB's withdrawable construction, allowing the breaker to be removed from its separate chassis for inspection, servicing or replacement while supporting efficient switchboard maintenance.

Reliable Circuit 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 LI release continuously monitors current and provides long-time overload and instantaneous short-circuit protection, allowing the breaker to disconnect the affected circuit when operating conditions exceed the configured protection thresholds.

The withdrawable Emax 2 construction is particularly useful in critical switchboards where serviceability and operational efficiency are important. The breaker can be isolated from its chassis for maintenance or replacement, while the E2.2H platform combines high breaking performance with ABB's modular approach to low-voltage power distribution.

Typical Applications

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