1SDA073101R1 ABB E4.2V 2500 Ekip Dip LI 4p WMP Air Circuit Breaker 2500 A

Why Choose the ABB E4.2V 2500 Ekip Dip LI 4p WMP Air Circuit Breaker?

The ABB E4.2V 2500 Ekip Dip LI 4p WMP, order code 1SDA073101R1, is a high-performance four-pole air circuit breaker (ACB) moving part from the ABB SACE Emax 2 range, engineered for protection and switching in demanding low-voltage power distribution systems. With a rated uninterrupted current of 2500 A, it is designed for high-current industrial, commercial, infrastructure and critical-power switchboards.

This E4.2V breaker is equipped with an Ekip Dip LI electronic trip unit, providing long-time overload (L) and instantaneous short-circuit (I) protection. The Ekip Dip platform provides dependable electronic overcurrent protection with adjustable thresholds, allowing the breaker protection to be coordinated with the characteristics of the connected distribution system.

The V performance level delivers exceptionally high short-circuit performance, with a rated ultimate short-circuit breaking capacity of 150 kA at 400 V AC and a rated short-time withstand current of 100 kA for 1 s. The four-pole WMP configuration is the moving part of a withdrawable Emax 2 breaker system, supporting efficient inspection, maintenance and replacement in high-availability switchboards.

High-Performance Protection for Critical Power Distribution

Air circuit breakers such as the ABB E4.2V protect high-current electrical distribution circuits against potentially damaging overload and short-circuit conditions. The Ekip Dip LI electronic release provides long-time overload and instantaneous short-circuit protection, with adjustable thresholds allowing the protection characteristics to be matched to the requirements of the installation.

The E4.2V is particularly suited to systems with very high prospective fault currents. Its 150 kA breaking capacity at 400 V AC and 100 kA short-time withstand capability for 1 s provide robust fault-handling performance, while the withdrawable Emax 2 architecture supports efficient servicing in critical switchboards where system availability and maintainability are important.

Typical Applications

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