ANM-H3 / MEGA Bolt-Down Automotive Fuse Holder (32V, up to 500A)

Heavy-duty bolt-down holder for MEGA/ANM flat fuses. Copper conductors, M8 studs, and 5 Nm specified clamp torque for low impedance connections in 12/24/32V DC systems (car audio, auxiliary battery, inverters, winches, upfitting). Verify available fault current and ensure the chosen fuse curve is appropriate for the application.

FAQs

Which fuse formats fit this holder?
MEGA/ANM-style bolt-down fuses with flat blades and M8 mounting pattern, 50A–500A.
What system voltage is supported?
32 V DC maximum. Suitable for 12V and 24V automotive and accessory systems.
What torque should I use on the studs?
Apply 5 Nm to the M8 studs to clamp the fuse and ring lugs. Follow your lug manufacturer’s torque for the cable side if different.
Is the holder high-interrupt rated?
This is for low breaking-capacity applications. Select fuses appropriate to the system’s prospective fault current.
What materials are used for the current path?
High-conductivity copper for low resistance and controlled thermal rise.
Can I use this for car audio amplifiers and sub systems?
Yes. Common as a mainline protection device between the battery and distribution block.
How do I choose the fuse amp rating?
Fuse to the conductor ampacity and expected load/inrush. Use the lowest rating that supports normal operation.
What ring lug size do I need?
M8 ring lugs sized to your cable gauge. Use manufacturer-approved crimp tooling.
Does it include a protective cover?
Variants with insulating covers are available. Request a covered version if needed.
Where should I mount the holder?
As close to the power source as practical to minimize unprotected cable length. Secure to a flat, rigid surface.
Is it suitable for marine or RV use?
Yes. For corrosive/wet areas, use covered versions and corrosion-resistant hardware.
What’s the maximum fuse rating?
Up to 500A within a 32V DC system, provided cables/terminations are rated accordingly.
Are ANL/AML fuses compatible?
No. ANL/AML are a different footprint. This holder is for MEGA/ANM style. Ask for our ANL/AML holders.
Is it CE and RoHS compliant?
Yes. CE and RoHS declarations; no high-concern chemicals per supplier declaration.
Do you offer bulk/wholesale or OEM customization?
Yes—covers, hardware kits, labels/branding, and bulk pricing available.
What tools do I need for installation?
Calibrated torque wrench (5 Nm) and correct crimp tools for your ring lugs.
How can I minimize voltage drop at high current?
Use large-gauge copper, shortest practical runs, and clean, properly torqued terminations.
Can I mount it in the engine bay?
Yes, within component thermal limits and away from heat sources/moving parts. Add shielding if needed.
Do you supply matching MEGA/ANM fuses?
Yes. Add requested ratings (e.g., 50–500A) to your quote or order.
How do I protect exposed terminals?
Use insulating boots/covers; maintain clearance from grounded metal; grommet and loom pass-throughs.
Is it suitable as a lithium battery main fuse holder?
Yes—verify BMS trip behavior, inrush/surge, and available fault current. Select an appropriate fuse curve/rating.
What maintenance is recommended?
Re-torque after initial thermal cycles; inspect for discoloration or hot spots; keep terminals clean and dry.
