1SDA071637R1 ABB E2.2S 1600 Ekip G Touch LSIG 4p F HR Air Circuit Breaker 1600 A

Why Choose the ABB E2.2S 1600 Ekip G Touch LSIG 4p F HR Air Circuit Breaker?

The ABB E2.2S 1600 Ekip G Touch LSIG 4p F HR, order code 1SDA071637R1, is a high-performance four-pole air circuit breaker (ACB) designed for generator protection and demanding low-voltage electrical distribution systems. As part of the advanced ABB SACE Emax 2 series, it combines a 1600 A rated uninterrupted current with an Ekip G Touch LSIG electronic trip unit for comprehensive circuit and generator protection.

The Ekip G Touch LSIG solid-state release provides long-time overload, selective short-time, instantaneous short-circuit and earth-fault protection, together with protection functions developed for generator applications. Its touchscreen interface supports intuitive configuration and monitoring, making the breaker well suited to generating plants, critical power systems and sophisticated industrial distribution networks.

With a rated operational voltage of 690 V AC, four-pole configuration and fixed construction with rear flat horizontal terminals, the E2.2S 1600 is designed for integration into low-voltage switchboards. The S performance level provides a rated ultimate short-circuit breaking capacity of 85 kA at 400–440 V AC and 66 kA at 500–690 V AC, together with a short-time withstand current of 66 kA for 1 s.
