1SDA072621R1 ABB E6.2V 5000 Ekip Dip LI 3p WMP Air Circuit Breaker 5000 A

Why Choose the ABB E6.2V 5000 Ekip Dip LI 3p WMP Air Circuit Breaker?

The ABB E6.2V 5000 Ekip Dip LI 3p WMP, order code 1SDA072621R1, is a high-capacity three-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for protection and switching in demanding low-voltage power distribution systems. With a 5000 A rated uninterrupted current and ABB's Ekip Dip LI solid-state electronic trip unit, it provides adjustable long-time overload and instantaneous short-circuit protection.

The E6.2V is engineered for electrical installations with exceptionally high prospective fault currents. Its V-performance level provides a rated ultimate short-circuit breaking capacity of 150 kA at 400–415 V AC, making the breaker particularly suitable for major industrial, infrastructure and high-power distribution systems where reliable interruption of severe short-circuit currents is required.

The 1SDA072621R1 is the moving part of a withdrawable circuit breaker, designed for installation with the appropriate fixed part in compatible ABB SACE Emax 2 switchgear. Its 2000–5000 A adjustable overload setting and 7500–75000 A instantaneous short-circuit setting provide flexibility for coordinating protection with the characteristics of the connected electrical system.

High-Current 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 E6.2V combines a substantial 5000 A current rating with a 150 kA ultimate short-circuit breaking capacity at 400–415 V AC, making it particularly suitable for major incoming and distribution circuits where exceptionally high prospective fault currents must be safely interrupted.

The Ekip Dip LI electronic trip unit provides long-time overload (L) and instantaneous short-circuit (I) protection. Its adjustable 2000–5000 A overload range and 7500–75000 A instantaneous range enable protection settings to be coordinated with high-current electrical systems, while the withdrawable E6.2 construction supports efficient inspection and servicing within critical switchgear installations.
