ABB OESA-F30T6ASW Three-Phase Fusible Disconnect Switch

ABB OESA-F30T6ASW is a three-phase fusible disconnect switch rated at 30 A, configured as a 3-pole device for isolating three-phase electrical circuits. When operated to the OFF position, all three poles are opened, providing a safe disconnection point for servicing or fault isolation in electrical installations. This model belongs to ABB’s OESA family of fusible disconnects, a line of devices designed to interrupt and protect downstream circuits by incorporating a fuse element into the disconnect assembly. Applications typically include control panels and distribution schemes in industrial environments where a dedicated disconnect point is needed for 30 A circuits and three-phase loads. In industrial power distribution, such fusible disconnects serve as a clear, reliable means to isolate equipment for maintenance while providing overcurrent protection through the fusible elements.
