ABB 1SDA070886R1 Power Module

ABB 1SDA070886R1 is a SACE EMAX2 E1.2N three-pole power circuit-breaker with Ekip Touch LSIG, designed for fixed installation in low‑voltage switchgear and distribution panels. It is rated for a nominal current of 1600 A and provides a short‑circuit current rating (Icu) of 66 kA at 380 V, making it suitable for protecting large transformers, generator sets, and industrial feeders from overloads and short circuits while enabling local signaling and control through the LSIG interface. The device features front-terminal connections for straightforward assembly and maintenance, and it is commonly encountered in ABB’s BR packaging variants offered in regional catalogs, identified by the 1SDA070886R1 product code; as part of the EMAX2 E1.2N family, it serves applications requiring high-current, three‑phase protection in fixed installations.
