ABB OT16F3 Switch-Disconnector Outdoor High Voltage

ABB OT16F3 Switch-Disconnector is a 3-pole, non-fusible device rated for up to 600 V and 16 A, designed to isolate circuits in electrical installations. It is front-operated and available in base-mounted configurations, with DIN-rail mounting supported in certain variants; it uses protected clamp terminals and does not include a handle or shaft. The unit carries catalog number 1SCA104811R1001 and sits in ABB’s OT family, which covers 16–160 A switches-disconnectors for compact, robust isolation in industrial control panels and distribution gear. ABB literature documents the OT16F3 with a 600 V rating and 16 A current rating, and the OT family is noted for CSA C22.2 No.14 certification in historical data. This makes OT16F3 a suitable non-fusible three-pole disconnect for maintenance isolations and fault-clearance tasks within 600 V classes, aligning with ABB’s broader range of high-performance disconnectors.
