1SDA071647R1 ABB E2.2H 1600 Ekip G Touch LSIG 4-Pole Air Circuit Breaker

Why Choose the ABB 1SDA071647R1 E2.2H 1600 Ekip G Touch LSIG Air Circuit Breaker?

The ABB 1SDA071647R1 is a high-performance SACE Emax 2 E2.2H air circuit breaker engineered for protection, switching and isolation in demanding low-voltage power distribution and generator applications. Configured as an E2.2H 1600 Ekip G Touch LSIG 4p F HR, it combines a 1600 A rated uninterrupted current, four-pole construction and ABB's advanced Ekip G Touch LSIG solid-state electronic protection release.

The Ekip G Touch LSIG release provides Long-time (L), Short-time (S), Instantaneous (I) and Ground-fault (G) protection functions, together with generator-specific protection capabilities and integrated measurement functionality. Its touch-sensitive interface supports convenient configuration of protection parameters for critical generator and low-voltage distribution systems.

The 1SDA071647R1 is a fixed four-pole circuit breaker equipped with rear flat horizontal terminals. Rated for operation up to 690 V AC, the E2.2H performance level provides an ultimate short-circuit breaking capacity of 100 kA at 400/415 V AC and 85 kA at 690 V AC, making it suitable for high-fault-level industrial switchboards and critical power installations.

Reliable Protection for Low-Voltage Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 provide switching, isolation and protection for high-current low-voltage distribution circuits. The electronic protection release monitors electrical conditions and initiates circuit interruption when configured thresholds are exceeded, helping protect cables, switchgear, generators and connected equipment against overload, short-circuit and ground-fault conditions.

The Ekip G Touch LSIG release combines long-time overload, selective short-time, instantaneous short-circuit and ground-fault protection with generator-oriented functionality and integrated measurement capabilities. Together with the high-breaking-capacity E2.2H frame, 1600 A current rating, four-pole construction, fixed execution and rear flat horizontal terminals, the 1SDA071647R1 provides a comprehensive solution for demanding power distribution and generator protection systems.

Typical Applications

• Generator protection and generator distribution switchboards.
• Industrial low-voltage switchboards and distribution panels.
• Main incoming and outgoing power distribution circuits.
• Transformer secondary distribution and protection.
• Industrial plants and manufacturing facilities.
• Commercial, infrastructure and critical power systems.
