1SDA072322R1 ABB E2.2H 1250 Ekip Dip LSI 3p WMP Air Circuit Breaker

Why Choose the ABB E2.2H 1250 Ekip Dip LSI 3p WMP Air Circuit Breaker?

The ABB E2.2H 1250 Ekip Dip LSI 3p WMP, order code 1SDA072322R1, is a high-performance three-pole air circuit breaker (ACB) moving part from the ABB SACE Emax 2 range, designed for protection and switching in demanding low-voltage electrical distribution systems. Combining the E2.2H frame with a 1250 A rated current and ABB's Ekip Dip LSI electronic trip unit, it provides dependable protection for industrial, commercial and infrastructure power networks.

The breaker uses a withdrawable construction that supports efficient inspection, servicing and replacement within compatible Emax 2 switchgear. Its Ekip Dip LSI electronic trip unit provides long-time overload, short-time selective short-circuit and instantaneous short-circuit protection, enabling effective protection and coordination throughout low-voltage distribution systems.

With an E2.2H high-breaking-capacity frame and an ultimate short-circuit breaking capacity of 100 kA at 400/415 V AC, this 1250 A breaker is engineered for installations where substantial fault-current interruption capability is required. Its three-pole withdrawable moving-part format makes it suitable for main switchboards, industrial power distribution and other critical low-voltage applications.

Advanced LSI Protection for Low-Voltage Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 protect high-current low-voltage networks by detecting and interrupting potentially damaging overload and short-circuit conditions. The E2.2H performance level provides high fault-current interruption capability, making the 1SDA072322R1 particularly suitable for main distribution, incomer and high-current feeder applications.

The Ekip Dip LSI trip unit adds short-time protection to the long-time and instantaneous functions, allowing improved coordination with other protective devices in the electrical network. This can help maintain selectivity while protecting cables, busbars, transformers and connected equipment against overloads and short circuits.

Typical Applications

• Low-voltage main distribution switchboards.
• Industrial power distribution systems.
• Manufacturing and process plants.
• Commercial building electrical distribution.
• Data centres and critical power infrastructure.
• Utility and infrastructure switchgear.
• Transformer and generator distribution systems.
