1SDA071545R1 ABB E2.2H 800 Ekip Touch LSI 4-Pole Fixed Air Circuit Breaker

Why Choose the ABB E2.2H 800 Ekip Touch LSI 4p FHR Air Circuit Breaker?

The ABB E2.2H 800 Ekip Touch LSI 4p FHR, order code 1SDA071545R1, is a high-performance SACE Emax 2 air circuit breaker (ACB) designed for protection and switching in demanding low-voltage power distribution systems. Part of the ABB Emax 2 E2.2 series, this fixed four-pole circuit breaker combines an 800 A rated current with the advanced Ekip Touch LSI electronic trip unit.

The Ekip Touch LSI protection release provides long-time overload, short-time selective short-circuit and instantaneous short-circuit protection. Its touchscreen interface enables straightforward configuration and access to protection and electrical information, making the breaker well suited to modern switchboards where selective protection, monitoring and flexible system integration are important.

The E2.2H performance level provides a high 100 kA breaking capacity, while the breaker is rated for operation in low-voltage systems up to 690 V AC. Its fixed construction, four-pole arrangement and rear flat horizontal terminals make the 1SDA071545R1 a robust solution for main incomers, feeders and high-fault-level industrial distribution systems.

Selective Protection for Demanding Power Distribution

Air circuit breakers such as the ABB Emax 2 E2.2H protect critical low-voltage distribution circuits against damaging overload and short-circuit conditions. The high breaking performance of the H-class E2.2 frame makes this breaker particularly suitable for installations supplied by large transformers or other sources capable of producing substantial prospective fault currents.

The Ekip Touch LSI release adds short-time protection to the long-time and instantaneous functions, allowing improved selectivity between upstream and downstream protective devices. This can help isolate a fault closer to its source while maintaining supply to unaffected parts of the installation, an important consideration in industrial plants, infrastructure, data centres and other applications where continuity of electrical service matters.

Typical Applications

• Main low-voltage switchboards and power-distribution assemblies.
• Industrial main incomer and feeder protection.
• Transformer secondary distribution systems.
• Manufacturing and process facilities.
• Data centres and critical power infrastructure.
• Commercial and large building electrical distribution.
• Utility and infrastructure installations.
• High-fault-level low-voltage networks requiring selective protection.
