Selection and Fitment Tips

  • Fuse size: Use only mini blade fuses. This holder does not suit standard or micro blade types.
  • Location: Install near the battery or feed to protect the full cable length on both circuits.
  • Wiring: Use quality crimp or solder joins with heat shrink for strain relief and moisture resistance.
  • Repeated fuse operation: Diagnose overloads or wiring faults rather than increasing fuse values.

Why Choose Narva 54408BL?

It combines two protected circuits in one tidy, serviceable holder, saving space and simplifying wiring layouts.

With mini blade compatibility, protective cap and pre-wired tails, it streamlines clean, reliable installs for trade and DIY users alike.

What type of fuses does Narva 54408BL accept?
Mini blade fuses (ATM). It does not accept standard ATO/ATC or micro blade fuses.
How many circuits can it protect?
Two independent circuits. Each position uses its own mini blade fuse value.
What is the maximum fuse rating per position?
Up to 30A per fuse position, subject to the cable size and accessory current draw.
Is it suitable for 12V and 24V use?
Yes. The holder is rated 32V DC and suits both 12V and 24V automotive and marine systems.
Where should I install the twin holder in the circuit?
As close to the battery or power source as practical to protect the full cable run for both circuits.
Does it include a protective cap for the fuses?
Yes. A cap helps shield the fuses from dust and splashes for everyday environments.
How do I wire the holder into my loom cleanly?
Use the pre-wired tails. Splice into the positive feeds using quality crimps or solder, then heat shrink for strain relief and moisture resistance.
What fuse values should I select for each circuit?
Choose values that protect the smallest cable in each circuit and match the accessory’s current. Do not exceed the cable’s continuous ampacity.
Can it be mounted in the engine bay or exposed areas?
Yes, with sensible placement away from direct heat and moving parts. Secure the holder and cables to avoid vibration damage.
What should I check if one or both fuses keep blowing?
Look for shorts to ground, damaged insulation, undersized cable or an overcurrent device. Do not upsize the fuse to mask a fault.
