1SDA071579R1 ABB E2.2H 1000 Ekip Hi-Touch LSIG 4-Pole Fixed Air Circuit Breaker

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

The ABB E2.2H 1000 Ekip Hi-Touch LSIG 4p FHR, order code 1SDA071579R1, is a high-performance SACE Emax 2 air circuit breaker (ACB) designed for advanced 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 a 1000 A rated current with the advanced Ekip Hi-Touch LSIG solid-state electronic trip unit.

The Ekip Hi-Touch LSIG release provides long-time overload, short-time selective short-circuit, instantaneous short-circuit and ground-fault protection. The Hi-Touch platform adds advanced measurement and monitoring capabilities, making this configuration particularly suitable for critical distribution systems where comprehensive circuit protection, selectivity and detailed electrical supervision are required.

The E2.2H performance level provides an ultimate short-circuit breaking capacity of 100 kA at 400–440 V AC and 85 kA at 500–690 V AC. With a rated operational voltage of 690 V AC, fixed construction and rear flat horizontal terminals, the 1SDA071579R1 provides robust protection for main incomers, feeders and high-fault-level industrial power distribution systems.

Advanced Protection for Critical Power Distribution

Air circuit breakers such as the ABB Emax 2 E2.2H provide switching and protection at critical points within low-voltage electrical networks. The H-performance E2.2 frame combines high current-carrying capability with substantial short-circuit interruption performance, making it particularly suitable for transformer-fed switchboards and industrial systems where prospective fault currents can be high.

The Ekip Hi-Touch LSIG release combines four complementary protection functions with advanced monitoring capabilities. Long-time protection responds to sustained overloads, short-time protection supports selective coordination, instantaneous protection rapidly interrupts severe short circuits, and ground-fault protection detects potentially damaging current flowing to earth. This combination supports comprehensive protection of conductors, switchgear and connected equipment in sophisticated power distribution systems.

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 networks requiring selective and ground-fault protection.
