1SDA072522R1 ABB E4.2V 3200 Ekip Dip LSI 3p WMP Air Circuit Breaker 3200 A

Why Choose the ABB E4.2V 3200 Ekip Dip LSI 3p WMP Air Circuit Breaker?

The ABB E4.2V 3200 Ekip Dip LSI 3p WMP, order code 1SDA072522R1, is a high-performance three-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for reliable protection and switching in demanding low-voltage power distribution systems. With a 3200 A rated uninterrupted current and ABB's Ekip Dip LSI electronic trip unit, it provides long-time, short-time and instantaneous overcurrent protection.

The E4.2V combines substantial current-carrying capability with very high short-circuit performance. This V-performance model provides a rated ultimate short-circuit breaking capacity of 150 kA at 400 V AC, making it particularly suitable for industrial, infrastructure and commercial distribution systems with high prospective fault currents.

The 1SDA072522R1 is the moving part of a withdrawable circuit breaker and features a three-pole configuration with a rated voltage of 690 V AC. It is supplied with four auxiliary change-over contacts and circuit-breaker open/closed position indication, while the Ekip Dip LSI release provides adjustable overload and short-circuit protection for coordinated power distribution.

High-Performance 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 performance level is designed for installations with particularly high prospective fault currents, combining a 3200 A current rating with a substantial 150 kA breaking capacity at 400 V AC.

The Ekip Dip LSI electronic trip unit provides long-time overload, short-time selective short-circuit and instantaneous short-circuit protection. The addition of the short-time function compared with an LI release provides greater flexibility for protection coordination and selectivity, making the 1SDA072522R1 well suited to sophisticated high-current distribution systems.

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.
• Selective protection systems requiring LSI functionality.
• Electrical installations with high prospective short-circuit currents.
• Withdrawable switchgear assemblies requiring serviceable high-current circuit protection.
