1SDA071562R1 ABB E2.2S 1000 Ekip Dip LSI 4-Pole Fixed Air Circuit Breaker

Why Choose the ABB E2.2S 1000 Ekip Dip LSI 4p FHR Air Circuit Breaker?

The ABB E2.2S 1000 Ekip Dip LSI 4p FHR, order code 1SDA071562R1, is a high-performance SACE Emax 2 air circuit breaker (ACB) designed for switching and protection in low-voltage AC 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 an Ekip Dip LSI solid-state electronic trip unit.

The Ekip Dip LSI release provides long-time overload, short-time selective short-circuit and instantaneous short-circuit protection. This combination enables effective protection coordination in industrial and commercial distribution networks, while DIP-switch adjustment provides a practical method for configuring the principal protection settings without requiring a touchscreen interface.

The E2.2S performance level provides an ultimate short-circuit breaking capacity of 85 kA at 400–440 V AC and 66 kA at 500–690 V AC. With a rated operational voltage of 690 V AC, fixed construction and rear flat horizontal terminals, the 1SDA071562R1 is well suited to main switchboards, incomers and high-current feeder circuits in demanding power distribution installations.

Selective Protection for High-Current Power Distribution

Air circuit breakers such as the ABB Emax 2 E2.2S provide switching and protection at critical points within low-voltage distribution networks. The E2.2S frame combines high current-carrying capability with substantial short-circuit performance, making it suitable for main switchboards, transformer-fed distribution systems and industrial installations where continuity and selective fault isolation are important.

The Ekip Dip LSI release provides three complementary protection functions. Long-time protection responds to sustained overloads, short-time protection enables selective coordination during short-circuit conditions, and instantaneous protection responds rapidly to severe faults. Together these functions help protect conductors, switchgear and connected equipment while supporting coordinated operation with other protective devices.

Typical Applications

• Main low-voltage switchboards and distribution assemblies.
• Industrial main incomer and feeder protection.
• Transformer secondary distribution systems.
• Manufacturing and process plants.
• Commercial and infrastructure power distribution.
• Data centres and critical electrical systems.
• Large building-services installations.
• Low-voltage networks requiring selective short-circuit protection.
