1SDA071629R1 ABB E2.2N 1600 Ekip Hi-Touch LSIG 4-Pole Fixed Air Circuit Breaker

Why Choose the ABB E2.2N 1600 Ekip Hi-Touch LSIG 4p FHR Air Circuit Breaker?

The ABB E2.2N 1600 Ekip Hi-Touch LSIG 4p FHR, order code 1SDA071629R1, is a high-performance SACE Emax 2 air circuit breaker (ACB) designed for advanced protection and switching in demanding low-voltage AC power distribution systems. This fixed four-pole E2.2N configuration combines a 1600 A rated current with ABB's Ekip Hi-Touch LSIG solid-state electronic trip unit and rear flat horizontal main terminals.

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 breaker particularly suitable for critical electrical systems where comprehensive protection, selectivity and detailed supervision of the distribution network are required.

The E2.2N performance level provides an ultimate short-circuit breaking capacity of 66 kA from 400–690 V AC, with a rated short-time withstand current of 66 kA for 1 s. Rated for operation up to 690 V AC, the 1SDA071629R1 combines substantial fault interruption performance with fixed construction, four-pole switching and rear horizontal connections for integration into main switchboards and high-current distribution assemblies.

Advanced Protection for Critical Power Distribution

The ABB SACE Emax 2 E2.2N is engineered for switching and protection at critical points within high-current low-voltage networks. Its 1600 A current capability, 66 kA breaking capacity and strong short-time withstand performance make this configuration suitable for main distribution circuits where fault interruption, selectivity and continuity of service are important design considerations.

The Ekip Hi-Touch LSIG release combines four complementary protection functions. Long-time protection responds to sustained overloads, short-time protection enables selective coordination, instantaneous protection provides rapid interruption of severe short circuits, and ground-fault protection responds to potentially damaging earth-fault currents. Together with the advanced capabilities of the Hi-Touch platform, this provides a comprehensive protection solution for sophisticated power-distribution systems.

Typical Applications

• Main low-voltage switchboards and power-distribution assemblies.
• Industrial main incomer protection.
• High-current feeder circuits.
• Transformer secondary distribution systems.
• Manufacturing and process facilities.
• Data centres and critical power infrastructure.
• Commercial and large-building electrical distribution.
• Networks requiring selective short-circuit and ground-fault protection.
