1SDA072921R1 ABB E2.2H 1000 Ekip Dip LI 4p WMP Air Circuit Breaker 1000 A

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

The ABB E2.2H 1000 Ekip Dip LI 4p WMP, order code 1SDA072921R1, 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 uninterrupted 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 LI electronic trip unit, providing long-time overload and instantaneous short-circuit protection. The LI protection configuration offers dependable electronic protection for installations where overload and rapid short-circuit protection are required without the additional short-time or ground-fault functions provided by other Ekip trip-unit variants.

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 enables use within compatible Emax 2 withdrawable assemblies, supporting convenient isolation, servicing and replacement in critical power distribution installations.

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 LI trip unit provides electronic long-time protection against sustained overloads together with instantaneous protection against severe short circuits. Combined with the withdrawable Emax 2 architecture, this makes the breaker suitable for installations where high fault-current performance, dependable circuit protection, 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.
• Installations with high prospective short-circuit currents.
• Withdrawable switchgear systems requiring convenient maintenance and isolation.
