1SDA071712R1 ABB E2.2H 2500 Ekip Dip LSI 4p F HR Air Circuit Breaker 2500 A

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

The ABB E2.2H 2500 Ekip Dip LSI 4p F HR, order code 1SDA071712R1, is a high-performance four-pole air circuit breaker (ACB) designed for demanding low-voltage power distribution applications. Part of the ABB SACE Emax 2 series, it combines a 2500 A rated uninterrupted current with an Ekip Dip LSI solid-state electronic release for long-time overload, selective short-time and instantaneous short-circuit protection.

The Ekip Dip LSI trip unit provides adjustable electronic protection using straightforward DIP-switch settings. Long-time overload protection is adjustable from 0.4–1 × In, selective short-circuit protection from 0.6–10 × In and instantaneous short-circuit protection from 1.5–15 × In, allowing effective coordination with other protective devices throughout the electrical distribution system.

The E2.2H performance level delivers a rated ultimate short-circuit breaking capacity of 100 kA at 380–440 V AC and 85 kA at 500–690 V AC. Its four-pole fixed construction, rear horizontal terminals and factory-fitted auxiliary contacts make the 1SDA071712R1 a robust solution for high-current industrial, commercial and infrastructure switchboards.

High-Performance Selective Protection for Power Distribution

ABB SACE Emax 2 air circuit breakers provide switching, isolation and protection for high-current low-voltage distribution circuits. With its 2500 A current rating and short-circuit breaking capacity of up to 100 kA, the E2.2H 2500 is designed for installations where substantial load currents and high prospective short-circuit levels require robust protective performance.

The Ekip Dip LSI release combines long-time overload protection with selective short-time and instantaneous short-circuit protection. Adjustable DIP-switch settings enable the breaker to be coordinated with upstream and downstream devices, helping a correctly engineered distribution system isolate localised faults while maintaining supply to unaffected circuits wherever possible.

Typical Applications

• Low-voltage main distribution switchboards.
• High-current incoming supply circuits.
• Industrial electrical distribution systems.
• Manufacturing and process plants.
• Commercial building power distribution.
• Transformer and installation protection.
• High-current outgoing distribution feeders.
• Infrastructure and utility installations.
• Power distribution systems requiring selective short-circuit coordination.
