The ABB 1SDA104390R1 is a high-performance Emax 2 E4.2S/E9 air circuit breaker designed for switching and protection in demanding AC power distribution systems. Rated at 3200 A and configured for 900 V AC applications, this four-pole fixed circuit breaker combines the E4.2S/E9 frame with an advanced Ekip Hi-Touch LSIG electronic trip unit.
As part of the ABB SACE Emax 2/E9 series, the E4.2S/E9 is engineered for high-current installations requiring dependable protection at elevated AC operating voltages. The Ekip Hi-Touch LSIG release provides long-time, short-time, instantaneous and ground-fault protection functions, helping protect electrical distribution equipment against overloads, short circuits and earth faults.
The 1SDA104390R1 features a fixed four-pole configuration with rear flat horizontal terminals, a 3200 A current rating and a 900 V AC configuration. Its four-pole construction enables switching of the neutral conductor alongside the three phase conductors, making it suitable for compatible three-phase, four-wire high-current distribution systems requiring advanced electronic protection.
Air circuit breakers provide switching, isolation and fault protection for high-current electrical distribution systems. By detecting abnormal operating conditions and disconnecting affected circuits, they help protect cables, busbars, transformers, generators and other electrical equipment against potentially damaging overload, short-circuit and earth-fault conditions.
The Ekip Hi-Touch LSIG trip unit fitted to the ABB 1SDA104390R1 combines long-time, short-time, instantaneous and ground-fault protection with the advanced functionality of ABB's Ekip Hi-Touch platform. Together with the E4.2S/E9 frame, 3200 A current rating, four-pole construction and 900 V AC configuration, it provides a sophisticated protection solution for demanding high-current electrical distribution networks.
