1SDA072432R1 ABB E2.2H 2500 Ekip Dip LSI 3P WMP Air Circuit Breaker

Why Choose the ABB 1SDA072432R1 E2.2H 2500 Ekip Dip LSI Air Circuit Breaker?

The ABB 1SDA072432R1 is a high-performance Emax 2 E2.2H 2500 air circuit breaker moving part designed for protection and control in demanding low-voltage AC power distribution systems. Configured as an E2.2H 2500 Ekip Dip LSI 3p WMP, it combines a rated current of 2500 A with ABB's Ekip Dip electronic trip technology and comprehensive LSI protection functions.

As part of the ABB SACE Emax 2 air circuit breaker range, this E2.2H version is engineered for industrial plants, commercial buildings, infrastructure and critical power distribution. The H performance level provides a rated ultimate short-circuit breaking capacity of 100 kA at 400–440 V AC, while the E2.2 platform provides high short-time withstand performance for selective distribution-system design.

The breaker incorporates an Ekip Dip LSI solid-state release, providing long-time overload, short-time selective short-circuit and instantaneous short-circuit protection. Its three-pole withdrawable moving-part (WMP) configuration is designed for compatible Emax 2 withdrawable switchgear, helping simplify inspection, servicing and replacement in installations where continuity and maintainability are important.

Reliable Selective Protection for High-Current Distribution

Air circuit breakers protect low-voltage power systems by interrupting current when overloads or short circuits exceed configured protection thresholds. The ABB Emax 2 E2.2H platform combines substantial current-carrying capability, high breaking capacity and short-time withstand performance, making it well suited to main distribution and other critical switchboard positions.

The Ekip Dip LSI release provides greater protection flexibility than an LI-only release by adding a short-time delayed short-circuit function. This supports selective coordination between upstream and downstream protection devices, while long-time protection responds to sustained overloads and instantaneous protection provides rapid interruption of severe short circuits.

Typical Applications

• Main incoming protection in low-voltage switchboards.
• Industrial power distribution systems.
• Commercial and large-building electrical distribution.
• Transformer secondary and feeder protection.
• Generator and standby-power distribution systems.
• Manufacturing and process-industry switchgear.
• Infrastructure and critical-power installations.
• Withdrawable switchboards requiring high-current selective LSI protection.
