Sylvania Clark 5UU2-7305 Relay

The Sylvania Clark 5UU2-7305 is a Bulletin 7305 PM relay from the Joslyn Clark/Sylvania family of industrial relays, built to switch higher-current control circuits in legacy equipment and modern panels alike. This model sits in the long-running 5U/5UU2 PM relay lineage—identified in Joslyn Clark catalogs and distributor listings under the 7305 bulletin—and represents a configuration used in older Clark controls that continues to see service in nostalgic or retrofit applications. One verified coil option documented for the 7305 PM family is 440–480 V AC at 60 Hz, illustrating its suitability for higher-voltage control circuits often found in industrial environments. Typical use cases include interlocking and line-side switching in control panels, motor-start circuits, and other applications where a mechanical relay provides isolation between the control logic and the powered load. Although the branding has evolved through Clark, Joslyn Clark, and Sylvania over the decades, the 5UU2-7305 designation anchors this part within the same lineage of relays used across mid- to late-20th-century equipment. If your project calls for a legacy 5U/5UU2 PM relay configured for 7305, this model identifies a specific variant within that family, enabling compatibility with equipment designed around the 7305 bulletin’s specifications.
