1SDA072574R1 ABB E4.2V 4000 Ekip Touch LI 3p WMP Air Circuit Breaker 4000 A

Why Choose the ABB E4.2V 4000 Ekip Touch LI 3p WMP Air Circuit Breaker?

The ABB E4.2V 4000 Ekip Touch LI 3p WMP, order code 1SDA072574R1, is a high-performance three-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for protection and switching in demanding high-current low-voltage power distribution systems. With a 4000 A rated current and ABB's advanced Ekip Touch LI electronic trip unit, it provides long-time overload and instantaneous short-circuit protection.

The E4.2V is engineered for electrical installations with particularly high prospective fault currents. This V-performance model provides a rated ultimate short-circuit breaking capacity of 150 kA at 400 V AC, making it suitable for major industrial, infrastructure and commercial distribution systems where powerful and dependable fault interruption is required.

The 1SDA072574R1 is the moving part of a withdrawable circuit breaker, designed for installation with the appropriate separate chassis or fixed part. It features four auxiliary change-over contacts, open/closed circuit-breaker position indication and a touchscreen-based Ekip Touch interface, combining configurable electronic protection with practical switchgear servicing and system integration.

High-Fault-Level Protection for Critical Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 provide switching, isolation and circuit protection for high-current low-voltage electrical networks. The E4.2V combines a 4000 A current rating with a substantial 150 kA ultimate breaking capacity at 400 V AC, making it particularly suitable for incoming and distribution circuits where very high prospective fault currents must be safely interrupted.

The Ekip Touch LI electronic trip unit provides long-time overload (L) and instantaneous short-circuit (I) protection. Its touchscreen interface supports convenient interaction with protection settings and breaker information, while the withdrawable E4.2 construction enables practical inspection and servicing in critical high-current switchgear installations.

Typical Applications

• Main low-voltage electrical switchboards.
• Industrial power distribution systems.
• Manufacturing and process plant switchgear.
• Commercial and infrastructure power distribution.
• Transformer and installation protection.
• High-current incoming and distribution feeders.
• Electrical installations with high prospective short-circuit currents.
• Applications requiring adjustable overload and instantaneous protection.
• Critical electrical distribution panels requiring very high breaking capacity.
• Withdrawable switchgear assemblies requiring serviceable high-current circuit protection.
