Why Choose the ABB E2.2N 2500 Ekip Touch LSI 4p F HR Air Circuit Breaker?
The ABB E2.2N 2500 Ekip Touch LSI 4p F HR, order code 1SDA071695R1, is a high-current four-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range. Designed for fixed installation in demanding low-voltage distribution systems, it combines a 2500 A rated uninterrupted current with an Ekip Touch LSI solid-state electronic release for long-time overload, selective short-time and instantaneous short-circuit protection.
The Ekip Touch LSI release provides adjustable electronic protection through a touch-sensitive interface. 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, supporting effective protection coordination throughout high-current electrical distribution systems.
The E2.2N performance level provides a rated ultimate short-circuit breaking capacity of 66 kA from 380–690 V AC, with a rated short-time withstand current of 66 kA for 1 s and 50 kA for 3 s. Fixed construction, rear flat horizontal terminals and four auxiliary contacts make the breaker well suited to permanent integration within industrial and commercial low-voltage switchboards.

Selective High-Current 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, 66 kA ultimate short-circuit breaking capacity and substantial short-time withstand capability, the E2.2N 2500 is suited to main incomers and distribution feeders where dependable fault interruption and system selectivity are essential.
The Ekip Touch LSI release adds selective short-time protection to long-time overload and instantaneous short-circuit protection. This enables more sophisticated coordination between upstream and downstream protective devices, helping a correctly designed 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 secondary protection.
- High-current outgoing distribution feeders.
- Power distribution systems requiring selective short-circuit coordination.
