Blue Sea Systems MAXI Fuse Block Ignition Protected 80A

The Blue Sea Systems MAXI Fuse Block, PN 5006100, is the current ignition-protected replacement for the earlier discontinued PN 5006. It's a single-circuit, screw-terminal MAXI fuse block rated to 80A, with a snap-on terminal cover that insulates all conductive parts to satisfy ABYC/USCG requirements.

Key features

• 80A maximum, 32V DC maximum
• Screw terminals compress the fuse blades for low-resistance connections; accepts 14-4 AWG wire
• Snap-on terminal cover with breakouts for wire access from the sides or bottom
• Ignition protected: SAE J1171 and ISO 8846
• Label recess accepts a large-format label

This block accepts any Blue Sea MAXI fuse up to 80A (PN 5138-5143), making it the block to use where a single MAXI circuit needs both screw-terminal wiring and ignition protection — for example, a branch circuit inside a gasoline engine compartment.

Torque the screw terminals to 25 in-lb, and keep the CE certificate on hand if the installation needs to document ignition-protection compliance.

This block suits a single high-current accessory circuit that needs both screw-terminal wiring and ignition protection in one compact footprint — a common pairing is a bilge pump, windlass control, or accessory feed routed through an engine compartment. The screw-terminal design also makes it easy to service or re-terminate the circuit later without re-crimping a ring terminal, unlike stud-style fuse blocks. Keep in mind this block covers one circuit only — for a multi-circuit MAXI installation, pair several of these blocks together or step up to a panel-style fuse block designed for multiple positions. A torque driver rather than a hand screwdriver is worth using here to hit the 25 in-lb spec consistently.
