Why Choose the ABB E2.2H 2500 Ekip Touch LSI 4p FHR Air Circuit Breaker?
The ABB E2.2H 2500 Ekip Touch LSI 4p FHR, order code 1SDA071715R1, is a high-performance SACE Emax 2 air circuit breaker (ACB) designed for switching and selective protection in demanding low-voltage power distribution systems. This fixed four-pole E2.2H configuration combines a 2500 A rated uninterrupted current with ABB's Ekip Touch LSI solid-state electronic trip unit and rear horizontal main terminals.
The Ekip Touch LSI release provides long-time overload (L), short-time short-circuit (S) and instantaneous short-circuit (I) protection. Its electronic protection platform allows the breaker to protect against sustained overloads and severe faults while the adjustable short-time function supports selective coordination between upstream and downstream protective devices.
The E2.2H performance level is engineered for high-fault-level installations, with an ultimate short-circuit breaking capacity of 100 kA at 400 V AC and E2.2H series performance of 85 kA at 690 V AC. Together with its 690 V AC rated voltage, fixed four-pole construction and rear horizontal terminals, the 1SDA071715R1 is well suited to main switchboards, transformer secondary systems and high-current industrial distribution networks.
Key Advantages
- 2500 A rated uninterrupted current for high-current low-voltage distribution circuits.
- E2.2H high-breaking-capacity frame for demanding installations with substantial prospective fault currents.

Selective Protection for High-Current 2500 A Distribution
The ABB SACE Emax 2 E2.2H is engineered for important switching and protection duties where substantial prospective short-circuit currents can occur. Its 2500 A current rating and 100 kA Icu at 400 V AC make this configuration particularly suitable for main distribution points close to transformers and other high-capacity electrical supplies.
The Ekip Touch LSI release combines three complementary protection functions. Long-time protection responds to sustained overloads, short-time protection enables delayed fault clearance to support selective coordination, and instantaneous protection provides rapid interruption of severe short circuits. This combination helps protect conductors and switchgear while supporting coordinated power-distribution designs where continuity of unaffected circuits is important.
Typical Applications
- Main low-voltage switchboards and power-distribution assemblies.
- Industrial main incomer protection.
- Transformer secondary distribution systems.
- High-current feeder circuits.
- Manufacturing and process facilities.
- Data centres and critical power infrastructure.
- Large commercial and infrastructure electrical systems.
- High-fault-level networks requiring selective overload and short-circuit protection.
