Sea-Dog 420501-1 Fuse Holder with Push Cap, Brass/Bakelite, 10 Amp 12 Volt

The Sea-Dog 420501-1 is a panel-mounted fuse holder built to provide over-current protection in 12 volt DC marine electrical circuits. It uses a push-on cap for quick, tool-free access when checking or swapping a fuse, and is constructed of stamped brass contacts inside a molded bakelite body for durable, corrosion-resistant service in a marine environment. The holder is square in shape with a side release location, making it straightforward to mount into a panel or bulkhead. It is rated for a maximum of 10 amps at 12 volts and accepts a 1/4 inch x 1-3/4 inch fuse. For continued serviceability, Sea-Dog offers a matching replacement red insert (Sea-Dog 422199-1) sized for this fuse holder, so the holder itself does not need to be replaced if the insert wears out. This makes the 420501-1 a practical, long-term component for boat wiring panels, helm stations, and other 12 volt DC circuits that need reliable, accessible fuse protection.
