SDM3055 10A Current Fuse Replacement

Note: Opening your SDM3055 could void the warranty. Please contact [email protected] before performing this service.

To locate the fuse, first the case must be opened.

1. Rotate the handle to the upright position and remove it by pulling outward where the handle meets the case.

2. Remove the small screw located on the underside of the case.

3. Remove the rear feet/bezel. Older models will have two screws, while newer models will have 4 screws to remove the rear feet.

4. Once the rear bezel/feet are removed, slide the case upward to remove. Once the case is opened you can find the fuse location in the image below.

5. To remove the fuse, first pry up gently on the plastic housing from one of the ends. Due to the placement of this fuse, this is easier to do through the access hole on the side of the frame.

6. Once the clear plastic housing is removed you can then pry up gently on the fuse itself to release it from the holder.

7. Installation is the reverse of the removal. Replace with Littelfuse T12AH250V.
