1SDA071008R1 ABB E2.2S 1600 Ekip Hi-Touch LSI 3p F HR Air Circuit Breaker 1600 A

Why Choose the ABB E2.2S 1600 Ekip Hi-Touch LSI 3p F HR Air Circuit Breaker?

The ABB E2.2S 1600 Ekip Hi-Touch LSI 3p F HR, order code 1SDA071008R1, is a high-performance air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for switching, isolation and protection in demanding low-voltage power distribution systems. Its E2.2S frame provides a rated uninterrupted current of 1600 A and a rated operational voltage of 690 V AC, making it suitable for high-current industrial, commercial and infrastructure switchboards.

This model is equipped with an advanced Ekip Hi-Touch LSI electronic trip unit, providing long-time overload (L), short-time short-circuit (S) and instantaneous short-circuit (I) protection. The Hi-Touch platform combines sophisticated protection with enhanced measurement and monitoring capabilities, while short-time protection supports selective coordination between upstream and downstream protective devices.

The E2.2S performance class provides a rated ultimate short-circuit breaking capacity of 85 kA at 400–440 V AC and 66 kA at 500–690 V AC. The 1SDA071008R1 is a three-pole fixed circuit breaker with rear flat horizontal terminals, fitted with four auxiliary contacts and circuit-breaker open/closed position indication for integration into compatible low-voltage switchgear.

Advanced LSI Protection for Selective Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 E2.2S provide switching, isolation and protection for high-current low-voltage electrical networks. The E2.2S performance class combines a 1600 A current rating with 85 kA breaking capacity at 400–440 V AC and a 66 kA short-time withstand capability for 1 s, making it well suited to systems with substantial prospective fault currents.

The Ekip Hi-Touch LSI trip unit combines advanced electronic monitoring with three complementary protection functions. Long-time protection responds to sustained overloads, short-time protection permits controlled fault-clearing delays to improve selectivity with downstream devices, and instantaneous protection rapidly interrupts severe short circuits. This combination makes the 1SDA071008R1 particularly suitable for coordinated industrial and infrastructure distribution networks.

Typical Applications

• Main low-voltage distribution switchboards.
• Industrial power distribution systems.
• Transformer secondary protection.
• High-current feeder and incomer protection.
• Manufacturing and process plant switchgear.
• Commercial and infrastructure electrical installations.
• Critical power distribution systems.
• Networks requiring selective LSI protection and advanced electrical monitoring.
