1SDA071640R1 ABB E2.2S 1600 Ekip G Hi-Touch LSIG 4-Pole Fixed Air Circuit Breaker

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

The ABB E2.2S 1600 Ekip G Hi-Touch LSIG 4p FHR, order code 1SDA071640R1, is a high-performance SACE Emax 2 air circuit breaker (ACB) engineered for generator protection and demanding low-voltage power distribution systems. This fixed four-pole E2.2S breaker combines a 1600 A rated current with ABB's advanced Ekip G Hi-Touch LSIG solid-state electronic trip unit and rear horizontal main terminals.

The Ekip G Hi-Touch LSIG release provides long-time overload, short-time selective short-circuit, instantaneous short-circuit and ground-fault protection, together with protection functions specifically developed for generator applications. Integrated Ekip Measuring Pro and Network Analyzer functionality adds advanced electrical measurement and power-quality analysis, supporting detailed supervision of critical generation and distribution systems.

The E2.2S performance level provides an ultimate short-circuit breaking capacity of 85 kA at 380–440 V AC and 66 kA at 500–690 V AC. With a rated operational voltage of 690 V AC, fixed four-pole construction and rear horizontal connections, the 1SDA071640R1 is well suited to generator switchboards, standby power systems, main incomers and critical industrial distribution networks.
