Why Choose the ABB E2.2S 250 Ekip Touch LI 3p F HR Air Circuit Breaker?
The ABB E2.2S 250 Ekip Touch LI 3p F HR, order code 1SDA073631R1, is a three-pole fixed air circuit breaker from the ABB SACE Emax 2 range, designed for protection, switching and control in low-voltage power distribution systems. Rated at 250 A, it combines the E2.2S performance level with an Ekip Touch LI electronic trip unit providing long-time overload and instantaneous short-circuit protection.
The Ekip Touch platform provides an advanced interface for configuring and monitoring circuit protection while retaining the robust performance of the Emax 2 architecture. This fixed-version breaker uses adjustable rear horizontal (HR) terminals, providing a practical connection arrangement for integration into industrial, commercial and infrastructure switchboards.
The E2.2S frame provides a rated ultimate short-circuit breaking capacity of 85 kA at 440 V AC and a rated short-time withstand current of 66 kA for 1 s. Combined with its 250 A rating and Ekip Touch LI protection, the 1SDA073631R1 is a capable solution for feeder and distribution applications requiring dependable overload and high-level short-circuit protection.

Advanced LI Protection for Power Distribution
Air circuit breakers protect low-voltage distribution systems by interrupting abnormal currents before they can subject cables, busbars and connected equipment to unacceptable thermal or electrodynamic stress. The ABB E2.2S 250 combines an 85 kA ultimate breaking capacity at 440 V AC with electronic protection, making it suitable for distribution systems where dependable fault interruption and configurable overload protection are important.
The Ekip Touch LI trip unit provides long-time protection against sustained overloads together with instantaneous protection against severe short circuits. This LI configuration is well suited to applications where these core protection functions are required without the additional short-time and earth-fault functions included in LSI or LSIG trip-unit configurations.
Typical Applications
- Main and sub-main low-voltage power distribution switchboards.
- Industrial manufacturing and process facilities.
- Commercial building electrical distribution systems.
- Infrastructure and utility installations.
- Feeder protection requiring LI functionality.
- High-fault-level low-voltage distribution circuits.
