1SDA072922R1 ABB E2.2H 1000 Ekip Dip LSI 4p WMP Air Circuit Breaker 1000 A

Why Choose the ABB E2.2H 1000 Ekip Dip LSI 4p WMP Air Circuit Breaker?

The ABB E2.2H 1000 Ekip Dip LSI 4p WMP, order code 1SDA072922R1, is a high-performance four-pole air circuit breaker (ACB) moving part designed for protection, switching and isolation in demanding low-voltage electrical distribution systems. As part of the ABB SACE Emax 2 series, it combines a 1000 A rated current with the high-breaking-capacity E2.2H performance level and electronic overcurrent protection.

This Emax 2 circuit breaker is equipped with the Ekip Dip LSI electronic trip unit, providing long-time, short-time and instantaneous overcurrent protection. The LSI protection functions provide dependable overload and short-circuit protection while allowing selective coordination with other protective devices in the electrical distribution system.

The E2.2H 1000 provides a rated ultimate short-circuit breaking capacity of 100 kA at 440 V AC and a rated short-time withstand current of 85 kA for 1 s. Its four-pole withdrawable moving-part (WMP) construction is designed for use with a compatible Emax 2 fixed part, supporting convenient isolation, servicing and replacement in critical power distribution installations.

Selective High-Capacity Protection for Low-Voltage Power Distribution

Air circuit breakers such as the ABB Emax 2 E2.2H provide switching, isolation and overcurrent protection for high-current low-voltage distribution circuits. The H performance level is designed for installations with substantial prospective fault currents, combining a 100 kA breaking capacity at 440 V AC with an 85 kA short-time withstand capability for 1 s.

The Ekip Dip LSI trip unit provides electronic long-time protection against sustained overloads, short-time protection that supports selective coordination between protective devices and instantaneous protection against severe short circuits. Combined with the withdrawable Emax 2 architecture, these functions make the breaker particularly suitable for installations where high fault-current performance, protection selectivity, system availability and maintainability are important.

Typical Applications

• Low-voltage main distribution switchboards.
• Industrial electrical distribution systems.
• Commercial and infrastructure power distribution.
• Main incoming and high-current feeder protection.
• Industrial switchgear and power distribution assemblies.
• Distribution systems requiring selective short-circuit protection.
• Installations with high prospective short-circuit currents.
• Withdrawable switchgear systems requiring convenient maintenance and isolation.
