1SDA071655R1 ABB E2.2B 2000 Ekip Touch LSI 4-Pole Fixed Air Circuit Breaker

Why Choose the ABB E2.2B 2000 Ekip Touch LSI 4p FHR Air Circuit Breaker?

The ABB E2.2B 2000 Ekip Touch LSI 4p FHR, order code 1SDA071655R1, is a SACE Emax 2 air circuit breaker (ACB) designed for switching and selective protection in high-current low-voltage power distribution systems. This fixed four-pole E2.2B configuration combines a 2000 A rated current with ABB's Ekip Touch LSI 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 touchscreen interface enables intuitive configuration and supervision, while the short-time protection function supports selective coordination between upstream and downstream protective devices to help maintain continuity of supply to unaffected circuits.

The E2.2B performance level provides an ultimate short-circuit breaking capacity of 42 kA at 440 V AC and a rated short-time withstand current of 42 kA for 1 s. With a rated operational voltage of 690 V AC, fixed construction and rear horizontal connections, the 1SDA071655R1 is well suited to main switchboards, transformer secondary systems and high-current industrial or commercial distribution networks.

Selective Protection for High-Current Power Distribution

The ABB SACE Emax 2 E2.2B provides switching and fault protection at important points within low-voltage distribution networks. Its 2000 A current capability, 42 kA short-circuit breaking performance and robust fixed construction make this configuration suitable for main distribution circuits, transformer-fed switchboards and substantial industrial feeders.

The Ekip Touch LSI release combines three complementary protection functions. Long-time protection responds to sustained overloads, short-time protection enables time-selective coordination with downstream devices, and instantaneous protection provides rapid interruption of severe short circuits. This combination helps protect conductors and switchgear while allowing coordinated distribution systems to isolate faults as selectively as the protection design permits.

Typical Applications

• Main low-voltage switchboards and distribution assemblies.
• Industrial main incomer protection.
• High-current feeder circuits.
• Transformer secondary distribution systems.
• Manufacturing and process facilities.
• Commercial building power distribution.
• Infrastructure and utility distribution systems.
• Networks requiring selective overload and short-circuit protection.
