ABB 708392-T6 K-Line 48VDC Control Relay Assembly

ABB 708392-T6 is a 48 VDC coil control relay assembly designed for K-Line Red systems, functioning as the Control Device Assembly (When Used) within ABB’s K-Line renewal parts lineup. This 48 VDC coil relay serves as the switching interface that translates a low-current control signal into the actuation of the connected load, enabling reliable on/off control within control panels, interlock circuits, and automation cabinets that rely on K-Line control logic. The T6 variant is one option in the 708392 family; ABB’s documented line-up also includes 708392T09 (110/120 VAC), 708392T16 (208/240 VAC), 708392T07 (125 V DC), and 708392T08 (250 V DC), illustrating how the same relay assembly adapts to different voltage rails while preserving mechanical and electrical form factors for K-Line installations. Typical applications include renewal or replacement parts in ABB K-Line control circuits used in industrial automation, PLC-based control architectures, and motor control setups where a dedicated 48 VDC control input is required to actuate the relay. This designation supports interoperability with K-Line controllers and ABB peripheral accessories, helping maintain consistent control interfaces across ABB’s automation ecosystem.
