Robust ANL fuse mounting for high-current DC systems

When you’re protecting large inverters, winches, DC-DC chargers or house battery banks, the quality of your fuse holder matters as much as the fuse itself. This Blue Sea ANL fuse holder is designed for reliable, serviceable installation in demanding 12V and 24V electrical systems, providing a secure mounting point for 35A to 750A ANL fuses (fuse sold separately) while helping reduce the risk of loose connections, heat build-up and accidental shorting.

The standout advantage is the swing-out design. It allows fuse inspection or replacement without removing mounting fasteners, which is particularly valuable in tight engine bays, battery compartments, caravans and marine electrical panels. Less disturbance to cabling also means less chance of stressing lugs or compromising cable routing during routine maintenance.

Designed for safer, cleaner installs

The included insulating cover is more than a dust shield—it supports safer operation by reducing the chance of accidental contact with live terminals. It also meets ABYC/USCG requirements, making it a suitable choice for marine and other regulated environments where protected terminations are expected.

With 5/16" (M8) studs to suit common ring terminals and stainless hardware engineered for corrosion resistance, this holder is well suited to marine, 4WD, caravan and off-grid applications where vibration and moisture can quickly expose weaknesses in generic fuse mounts.

Key features

• Swing-out fuse access for faster servicing without removing fasteners
• Insulating cover included with directional breakouts for flexible cable entry
• Corrosion-resistant studs designed for strong electrical contact and reliable torque
• Heat-resistant UL 94-V0 base for durability in high-load environments
• Accepts 35A–750A ANL fuses for a wide range of high-current protection needs

Where this fuse holder fits best

This is a practical choice when you need a tidy, professional fuse installation close to the battery or primary distribution point—especially where high current draw and harsh conditions make connection integrity critical. Typical uses include:

• Caravan and RV battery systems (12V/24V)
• 4WD touring setups with auxiliary batteries and inverters
• Marine house banks and DC distribution
• Off-grid DC power systems and battery enclosures

Important compatibility notes

Rated for DC systems up to 32V, making it suitable for most 12V and 24V installations. Ensure your selected ANL fuse rating matches the circuit design and cable sizing. As with any high-current connection, correct lug crimping, clean mating surfaces and appropriate torque practices help minimise voltage drop and unwanted heating.

Build a safer high-current DC circuit

If you’re upgrading a high-load DC circuit or building a new battery system, this Blue Sea holder provides a service-friendly, compliant mounting solution for ANL fuses—ideal for marine, caravan and 4WD electrical work. Select your required ANL fuse rating and install with confidence in a cleaner, more maintainable setup.
