Why Choose the ABB E2.2S 250 Ekip Dip LSI 3p FHR Air Circuit Breaker?
The ABB E2.2S 250 Ekip Dip LSI 3p FHR, order code 1SDA073629R1, is a 250 A three-pole fixed SACE Emax 2 air circuit breaker designed for protection and switching in low-voltage power distribution systems. It combines the ABB E2.2S frame with an Ekip Dip LSI electronic trip unit and horizontal rear terminals for integration into fixed switchboard assemblies.
The fitted Ekip Dip LSI release provides long-time overload, selective short-time short-circuit and instantaneous short-circuit protection. The long-time threshold is adjustable from 0.4–1 × In, while the protection settings are configured using DIP switches for straightforward coordination with downstream and upstream protective devices.
With a rated operational voltage of 690 V AC, rated insulation voltage of 1000 V AC, ultimate short-circuit breaking capacity of 85 kA at 400 / 415 V AC and rated short-time withstand current of 66 kA for 1 s, the E2.2S 250 provides robust protection for industrial, commercial and infrastructure power distribution systems.
Key Advantages
- 250 A rated current for low-voltage power distribution circuits.
- Ekip Dip LSI electronic trip unit provides three-stage overcurrent protection.
- Long-time (L) protection protects circuits against sustained overload conditions.
- Short-time (S) protection supports selective short-circuit protection and coordination.
- Instantaneous (I) protection responds rapidly to high short-circuit currents.
- High ultimate breaking capacity of 85 kA at 400 / 415 V AC.
- Three-pole fixed construction for three-phase power distribution systems.
- Horizontal rear terminals support practical rear-connected switchboard layouts.
- Part of ABB's established SACE Emax 2 air circuit breaker platform.

Selective LSI Protection for Low-Voltage Distribution
The Ekip Dip LSI electronic release provides three complementary protection functions for power distribution circuits. Long-time protection responds to sustained overloads, short-time protection provides controlled response to short-circuit currents and supports selective coordination, while instantaneous protection provides rapid tripping when very high fault currents occur.
The E2.2S performance level provides an ultimate short-circuit breaking capacity of 85 kA at 400 / 415 V AC together with a rated short-time withstand current of 66 kA for 1 s. Combined with fixed mounting and horizontal rear terminals, ABB 1SDA073629R1 is well suited to switchboards requiring high breaking performance and adjustable LSI protection.
Typical Applications
- Low-voltage main and sub-distribution switchboards.
- Industrial three-phase power distribution systems.
- Manufacturing and process plant electrical distribution.
- Commercial building power distribution.
- Infrastructure and utility low-voltage switchgear.
- Distribution systems requiring selective short-circuit coordination and adjustable electronic protection.
