Blue Sea Systems 5064 ATO/ATC In-Line Fuse Holder, 30 Amp Maximum

The Blue Sea Systems 5064 is an in-line fuse holder built to accept standard ATO or ATC blade-style fuses, letting you add point-of-use circuit protection anywhere along a wire run without a panel or fuse block. The housing is molded from plastic and mounts using a through-hole mounting type, making it a compact option for tucking into tight spaces behind panels, under helm stations, or inline with accessory wiring. It accepts wire from 12 to 18 AWG and comes supplied with 12 AWG pigtail leads on each end, ready to be spliced or crimped into an existing circuit. Maximum fuse amperage is 30 Amps, so it is sized for lighting circuits, pumps, electronics, and other moderate-draw accessory loads rather than high-current feeds. The fuse itself is sold separately, so pick the ATO or ATC amperage rating that matches the circuit you are protecting. Blue Sea Systems also notes compatibility for use with its ANL fuse blocks as part of a broader circuit protection setup. This is a simple, functional part: no motors, no electronics, just a reliable physical connection point that keeps a fuse accessible for inspection and replacement instead of buried in a wire loom.
