Why Choose the ABB E2.2N 800 Ekip Dip LSIG 3p F HR Air Circuit Breaker?

The ABB E2.2N 800 Ekip Dip LSIG 3p F HR, order code 1SDA070893R1, is a high-performance air circuit breaker (ACB) designed for protection and switching in low-voltage power distribution systems. As part of the advanced ABB SACE Emax 2 series, this E2.2 frame circuit breaker combines high short-circuit performance with comprehensive electronic protection for industrial, commercial and infrastructure electrical installations.

The breaker is equipped with an Ekip Dip LSIG solid-state electronic trip unit, providing long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection. This comprehensive protection package helps safeguard electrical equipment and distribution networks against a broad range of fault conditions while supporting selective and reliable operation within modern low-voltage switchboards.

With a rated uninterrupted current of 800 A, a rated operational voltage up to 690 V AC and a rated ultimate short-circuit breaking capacity of 66 kA at 440 V AC, the E2.2N 800 is suitable for demanding power distribution applications. This model is a three-pole fixed circuit breaker with rear horizontal terminals, providing a robust connection arrangement for integration into compatible switchgear assemblies.

Comprehensive LSIG Protection for Low-Voltage Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 E2.2N protect high-current electrical distribution circuits against overloads, short circuits and ground faults while also providing dependable switching and isolation. The E2.2N frame combines substantial short-circuit capability with flexible installation options, making it suitable for main distribution boards, industrial switchgear and other installations where high prospective fault currents can occur.

The Ekip Dip LSIG trip unit provides electronic long-time, short-time, instantaneous and ground-fault protection functions. The additional ground-fault function distinguishes the LSIG configuration from LSI versions and provides enhanced protection for electrical distribution systems where earth and ground faults must be detected and cleared reliably.

Typical Applications

• Main low-voltage distribution switchboards.
• Industrial power distribution systems.
• Commercial and infrastructure electrical installations.
• Transformer secondary protection.
• Manufacturing and process plant switchgear.
• Power distribution panels and switchgear assemblies.
• High-current feeder and incomer protection.
• Electrical distribution systems requiring LSIG and ground-fault protection.
