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.
