The Gould J266 Fuse Reducer is designed to adapt a 200A fuse holder or fuse block to accept a 60A Class J fuse, rated at 600V. This reducer is ideal for retrofitting existing 200A fusible equipment — such as fuse blocks, disconnect switches, and panelboards — where a lower 60A branch circuit or feeder protection is required without replacing the entire holder or block. It is compatible with standard Class J fuse holders and clips rated 200A/600V from Gould (now Mersen/Ferraz Shawmut) and equivalent brands. Cross-reference with your existing holder or block model to confirm a proper fit — send us your fuse holder or disconnect model and we'll confirm compatibility.
The J266 reducer is rated for 600V and steps down a 200A Class J fuse holder to accept a 60A Class J fuse. Only Class J fuses rated 60A or less and 600V should be used with this reducer to maintain proper protection and safety ratings.
The Gould brand was acquired by Ferraz Shawmut and is now sold under the Mersen brand. The J266 may have a direct Mersen equivalent — our team specializes in cross-referencing obsolete and hard-to-find fuse accessories. Contact us with the J266 part number and we'll help identify a compatible current replacement if needed.
The J266 is specifically designed for Class J fuse holders and blocks with 200A-rated clips. It is not interchangeable with Class R, Class K, or other fuse class holders. Always verify that your disconnect switch or fuse block is rated for Class J fuses before installing this reducer — feel free to contact our team for confirmation.
