GE THN3321 is a 30 A, 240 V, 3-phase non-fusible safety switch disconnect designed for industrial power isolation. As a non-fusible device, it provides a dedicated off position to safely disconnect a three-phase circuit without internal fuses. It is used to isolate power to motors, equipment, or control panels in 240 V three-phase systems, providing a reliable disconnect point for maintenance or safety shutdown in industrial environments.
