Why Choose the ABB E2.2S 2000 Ekip Touch LSI 3p FHR Air Circuit Breaker?
The ABB E2.2S 2000 Ekip Touch LSI 3p FHR, order code 1SDA071045R1, is a high-performance SACE Emax 2 air circuit breaker (ACB) designed for protection and control of demanding low-voltage electrical distribution systems. Rated at 2000 A, this three-pole fixed circuit breaker combines the E2.2S frame with ABB's advanced Ekip Touch LSI electronic trip unit.
The Ekip Touch LSI release provides electronic long-time overload (L), short-time short-circuit (S) and instantaneous short-circuit (I) protection. This combination supports effective protection and selective coordination within industrial and commercial distribution networks, while the touchscreen-based Ekip Touch platform provides an intuitive interface for configuring and supervising the protection functions.
This configuration is a fixed three-pole breaker equipped with rear horizontal (HR) terminals. The E2.2S version provides an ultimate short-circuit breaking capacity of 85 kA at 400/415 V AC, a rated short-time withstand current of 66 kA for 1 s and a rated operational voltage up to 690 V AC, making it suitable for high-current switchboards, main distribution panels and critical power systems.

Advanced Protection for High-Current Power Distribution
Air circuit breakers such as the ABB SACE Emax 2 protect high-current low-voltage distribution systems against overloads and short circuits while providing controlled switching and isolation of major electrical circuits. The E2.2S frame combines high interruption capability with the flexibility required for main incomers, feeders and other important circuits within industrial and commercial switchboards.
The Ekip Touch LSI trip unit provides configurable electronic long-time, short-time and instantaneous protection, enabling the breaker to respond appropriately to different overcurrent and short-circuit conditions. Short-time protection is particularly useful where selective coordination between upstream and downstream protection devices is required, helping isolate faults while maintaining continuity elsewhere in the electrical distribution system.
Typical Applications
- Industrial low-voltage main distribution switchboards.
- Main incomer and high-current feeder protection.
- Manufacturing and process-industry electrical systems.
- Commercial building power distribution.
- Data centres and critical electrical infrastructure.
- Transformer secondary distribution systems.
- Generator and utility distribution circuits.
- Electrical systems requiring LSI protection and selective coordination.
