1SDA071693R1 ABB E2.2N 2500 Ekip Dip LSIG 4p F HR Air Circuit Breaker 2500 A

Why Choose the ABB E2.2N 2500 Ekip Dip LSIG 4p F HR Air Circuit Breaker?

The ABB E2.2N 2500 Ekip Dip LSIG 4p F HR, order code 1SDA071693R1, is a high-performance four-pole 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, it combines a 2500 A rated uninterrupted current with an Ekip Dip LSIG electronic protection release for dependable operation in demanding industrial, commercial and infrastructure electrical installations.

This fixed circuit breaker incorporates the Ekip Dip LSIG solid-state electronic trip unit, providing long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection. Protection settings are configured using DIP switches, enabling the breaker to provide coordinated protection for cables, busbars, switchgear and connected equipment within complex low-voltage distribution networks.

With a rated operational voltage of 690 V AC and an N performance level with 66 kA ultimate short-circuit breaking capacity at 400 V AC, the E2.2N 2500 provides substantial fault interruption capability for high-current distribution systems. This version features a fixed four-pole construction with rear flat horizontal terminals and is fitted with four auxiliary contacts and circuit-breaker open/closed position indication.

Comprehensive LSIG Protection for Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 protect high-current low-voltage distribution circuits against overloads, short circuits and other potentially damaging electrical faults. By interrupting fault currents when configured protection thresholds are reached, the circuit breaker helps protect cables, busbars, switchgear and connected equipment while supporting safe and reliable distribution of electrical power.

The Ekip Dip LSIG electronic trip unit adds earth-fault protection to the long-time, short-time and instantaneous functions provided by LSI releases. This comprehensive protection package, combined with the E2.2N frame's 66 kA breaking capacity, makes the 1SDA071693R1 particularly suitable for main and distribution switchboards where selective protection, high current capacity and dependable fault interruption are essential.

Typical Applications

• Main low-voltage electrical distribution switchboards.
• Industrial power distribution systems.
• Commercial buildings and infrastructure installations.
• Manufacturing and process facilities.
• High-current feeder and distribution circuits.
• Transformer and generator distribution systems.
• Systems requiring integrated earth-fault protection.
• Electrical switchgear and control assemblies.
