1SDA071124R1 ABB E4.2V 2500 Ekip Touch LI 3p FHR Air Circuit Breaker

Why Choose the ABB E4.2V 2500 Ekip Touch LI 3p FHR Air Circuit Breaker?

The ABB E4.2V 2500 Ekip Touch LI 3p FHR, order code 1SDA071124R1, is a high-performance SACE Emax 2 air circuit breaker (ACB) designed for protection, switching and control of demanding low-voltage electrical distribution systems. Rated at 2500 A, this three-pole fixed circuit breaker combines the high-breaking-capacity E4.2V frame with ABB's advanced Ekip Touch LI electronic trip unit.

The Ekip Touch LI release provides long-time overload (L) and instantaneous short-circuit (I) protection through ABB's electronic Ekip platform. This configuration provides dependable protection against sustained overloads and severe short circuits while offering an advanced user interface and electronic protection architecture for modern industrial and infrastructure power distribution systems.

This configuration is a fixed three-pole breaker equipped with rear horizontal (HR) terminals. The E4.2V performance level provides an ultimate short-circuit breaking capacity of 150 kA at 400/415/440 V AC, 100 kA at 690 V AC and a rated short-time withstand current of 100 kA for 1 s, making the 1SDA071124R1 particularly suitable for high-fault-level switchboards and critical high-current distribution circuits.

High-Performance Protection for Critical Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 protect high-current low-voltage distribution systems against damaging overloads and short circuits while providing controlled switching and isolation of major electrical circuits. The E4.2V frame combines a substantial 2500 A current rating with exceptional short-circuit interruption capability, making it suitable for installations where very high prospective fault currents must be safely controlled.

The Ekip Touch LI trip unit provides electronic long-time overload and instantaneous short-circuit protection. Combined with the E4.2V frame's 150 kA breaking capacity at 400/415/440 V AC and 100 kA one-second withstand capability, this configuration provides robust protection for main distribution systems, transformer-fed switchboards and other critical high-power electrical installations.

Typical Applications

• Industrial low-voltage main distribution switchboards.
• Main incomer and high-current feeder protection.
• High-fault-level electrical distribution systems.
• Manufacturing and process-industry switchboards.
• Data centres and critical electrical infrastructure.
• Transformer secondary distribution systems.
• Power generation and utility distribution installations.
• Electrical systems requiring high breaking capacity and advanced LI electronic protection.
