1SDA071671R1 ABB E2.2S 2000 Ekip Dip LI 4p FHR Air Circuit Breaker

Why Choose the ABB E2.2S 2000 Ekip Dip LI 4p FHR Air Circuit Breaker?

The ABB E2.2S 2000 Ekip Dip LI 4p FHR, order code 1SDA071671R1, is a high-performance four-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for protection and control of high-current low-voltage electrical distribution systems. Combining a 2000 A rated uninterrupted current with an Ekip Dip LI electronic trip unit, it provides dependable long-time overload and instantaneous short-circuit protection for industrial, commercial and infrastructure power distribution applications.

This E2.2S circuit breaker is supplied in a fixed four-pole configuration with rear horizontal terminals. Its Ekip Dip LI solid-state electronic release provides long-time overload and instantaneous short-circuit protection, offering straightforward adjustment for applications where selective short-time protection and integrated earth-fault protection are not required.

With a 2000 A rated uninterrupted current, an S short-circuit performance level and a rated ultimate short-circuit breaking capacity of 85 kA at 440 V AC, the 1SDA071671R1 is engineered for substantial power distribution duties. The E2.2S platform also provides a rated short-time withstand current of 66 kA for 1 second, delivering robust fault-current capability for demanding low-voltage switchboards.

High-Current Circuit Protection for Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 E2.2S provide switching, isolation and protection for high-current low-voltage distribution circuits. They are commonly installed as incoming, outgoing or main distribution breakers in electrical switchboards where dependable interruption of overload and short-circuit currents is essential for protecting equipment and maintaining continuity of supply.

The Ekip Dip LI electronic trip unit provides a streamlined combination of long-time overload and instantaneous short-circuit protection. This makes it particularly suitable for circuits where adjustable overload protection and rapid interruption of severe short circuits are required without the additional selective short-time or earth-fault functions offered by LSI and LSIG releases.

Typical Applications

• Low-voltage main distribution switchboards.
• Industrial power distribution systems.
• Commercial and infrastructure electrical installations.
• Incoming and outgoing feeder protection.
• Transformer distribution systems.
• Manufacturing and process industry switchgear.
• Data centres and critical power installations.
• High-current circuits requiring LI electronic protection.
