Why Choose the ABB E2.2S 250 Ekip Hi-Touch LSI 4p FHR Air Circuit Breaker?
The ABB E2.2S 250 Ekip Hi-Touch LSI 4p FHR, order code 1SDA073645R1, is a 250 A four-pole fixed SACE Emax 2 air circuit breaker engineered for advanced protection and switching in low-voltage power distribution systems. It combines the E2.2S performance level with an Ekip Hi-Touch LSI electronic trip unit and horizontal rear terminals.
The fitted Ekip Hi-Touch LSI release provides long-time overload, short-time short-circuit and instantaneous short-circuit protection. The advanced Hi-Touch trip-unit platform provides comprehensive protection, measurement and system-management capabilities for applications requiring greater functionality than basic electronic releases.
The E2.2S 250 configuration provides an 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. Its four-pole fixed construction and horizontal rear terminals make it well suited to industrial, commercial and infrastructure switchboards requiring advanced LSI protection and neutral switching.
Key Advantages
- 250 A rated uninterrupted current for low-voltage distribution circuits.
- Ekip Hi-Touch LSI electronic trip unit provides advanced three-stage overcurrent protection.
- Long-time (L) protection safeguards circuits against sustained overload conditions.
- Short-time (S) protection supports selective short-circuit coordination.
- Instantaneous (I) protection provides rapid response to severe short-circuit currents.
- High 85 kA ultimate breaking capacity at 440 V AC.
- 66 kA short-time withstand current for 1 s supports demanding distribution applications.
- Four-pole fixed construction supports three-phase systems requiring neutral switching.
- Horizontal rear terminals suit rear-connected switchboard and busbar arrangements.

Advanced LSI Protection for Low-Voltage Distribution
The Ekip Hi-Touch LSI electronic trip unit provides coordinated protection across three principal overcurrent functions. Long-time protection responds to sustained overload conditions, short-time protection provides a controlled response to short-circuit currents for improved selectivity, and instantaneous protection enables rapid interruption of severe faults.
The E2.2S performance level combines an ultimate short-circuit breaking capacity of 85 kA at 440 V AC with a rated short-time withstand current of 66 kA for 1 s. Together with its four-pole fixed construction and horizontal rear terminals, ABB 1SDA073645R1 provides an advanced protection solution for switchboards requiring high fault performance, neutral switching and sophisticated electronic protection.
Typical Applications
- Low-voltage main and sub-distribution switchboards.
- Industrial three-phase power distribution systems requiring neutral switching.
- Manufacturing and process plant electrical distribution.
- Commercial building power distribution systems.
- Infrastructure and utility low-voltage switchgear.
- Distribution systems requiring advanced LSI electronic protection and selective short-circuit coordination.
