Blue Sea Systems MAXI Fuse Block, 30-80A, 32V DC, Ignition Protected

Overview

The Blue Sea Systems 5006100 is a MAXI fuse block for one 30A to 80A fused circuit on DC systems up to 32V. It takes MAXI fuses and gives you a clean, covered connection point when a single higher-amperage branch circuit needs protection without stepping up to a larger fuse panel.

This version replaces Blue Sea Systems 5006 and includes a snap-on terminal cover that insulates conductive parts. It is ignition protected, mounts with #10 screws, and accepts wire from the sides or the bottom, which helps when space around the block is limited.

It also accepts a wide wire range from 18 to 4 AWG and includes a label recess for circuit identification. That makes it easier to fit into existing boat wiring layouts and easier to service later when you need to trace or replace a fuse.

Key features

• Fits one MAXI fuse in the 30A to 80A range for a single protected branch circuit
• Rated for DC systems up to 32V
• Ignition protected housing with snap-on cover that insulates conductive parts
• Wire entry from the sides or the bottom for cleaner routing in tighter electrical spaces
• Screw terminals accept 18 to 4 AWG wire
• Mounts with #10 screws for a straightforward bulkhead or panel installation
• Label recess helps keep the circuit clearly identified
• Fuse is sold separately

Compatibility and fit

This block is for MAXI style blade fuses and one protected circuit, not a multi-circuit distribution panel. It suits installations up to 32V DC, which covers the voltage range used by common 12V and 24V boat systems when the chosen fuse size and cable are matched to the load.

It makes sense where a boat needs a compact fuse location near a battery switch, distribution point, or individual equipment feed. The covered layout is useful in electrical lockers and other onboard spaces where terminals need to stay protected but still easy to access for service.

Installation and setup

Mount the block on a flat surface with #10 fasteners and leave enough room to remove the cover and service the fuse. Side or bottom cable entry gives you more freedom when the block has to sit against a bulkhead or inside a tighter compartment.

Use a MAXI fuse sized for the circuit and tighten the screw terminals to 25 in-lb. That helps the fuse blades and cable terminations seat properly and keeps the connection stable in a marine environment where vibration is part of normal use.

Quality Boat Parts is a reseller. Many items include a manufacturer’s warranty, and all warranty service is handled directly by the manufacturer. We do not manage or administer warranty claims on behalf of customers.

Warranty terms, coverage, and duration are set by each manufacturer. Issues involving defects, repairs, or replacements must be addressed with the manufacturer’s support team. When available, the warranty period is listed on the product page. If it is not shown, contact us or the manufacturer for details before purchasing.

To start a claim, the customer must contact the manufacturer and follow their process. Keep your proof of purchase and original packaging, and register the product if the manufacturer requires it, as these are often needed for warranty service.
