1SDA071578R1 ABB E2.2H 1000 Ekip Hi-Touch LSI 4-Pole Fixed Air Circuit Breaker

Why Choose the ABB E2.2H 1000 Ekip Hi-Touch LSI 4p FHR Air Circuit Breaker?

The ABB E2.2H 1000 Ekip Hi-Touch LSI 4p FHR, order code 1SDA071578R1, is a high-performance SACE Emax 2 air circuit breaker (ACB) designed for advanced protection, measurement 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 a 1000 A rated current with the sophisticated Ekip Hi-Touch LSI electronic trip unit.

The Ekip Hi-Touch LSI release provides long-time overload, short-time selective short-circuit and instantaneous short-circuit protection together with advanced measurement capabilities. Integrated Ekip Measuring Pro functionality and network analysis capabilities make this version particularly suitable for installations where detailed electrical information, power-quality supervision and configurable circuit protection are required.

The E2.2H performance level provides an ultimate short-circuit breaking capacity of 100 kA at 380–440 V AC and 85 kA at 500–690 V AC. With a rated operational voltage of 690 V AC, fixed construction and rear horizontal terminals, the 1SDA071578R1 provides a robust solution for main incomers, feeders and critical high-current distribution circuits.

Advanced Protection and Power Monitoring

Air circuit breakers such as the ABB Emax 2 E2.2H provide critical switching and protection at key points in low-voltage distribution networks. The high breaking performance of the E2.2H frame makes this model particularly suitable for transformer-fed switchboards and industrial systems where prospective short-circuit currents can be substantial.

The Ekip Hi-Touch LSI release extends conventional circuit protection with advanced measurement and network analysis capabilities. Long-time protection responds to sustained overloads, short-time protection supports selective coordination with downstream devices, and instantaneous protection rapidly interrupts severe short circuits. Integrated measurement and analysis functions also provide valuable electrical information for system supervision, energy management and preventative maintenance.

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.
• Power systems requiring advanced electrical measurement and network analysis.
