Selection and Fitment Tips

  • Match amperage: Replace like-for-like at 50A unless the equipment manufacturer specifies otherwise.
  • Match the holder: Use an ANS compatible holder or block. ANS fuses do not fit MIDI, ANL or blade holders.
  • Location: Mount the holder close to the battery or source to protect the full cable run.
  • Investigate repeated blows: If a replacement fuse opens again, diagnose wiring faults or overload rather than increasing the fuse rating.

Why Choose Narva 53806?

It provides dependable, low-resistance protection in a compact bolt-down format that is ideal for modern accessory installs where space and efficiency matter.

Use it to safeguard medium to high current circuits while keeping voltage drop low and serviceability simple.

What is Narva 53806?
Narva 53806 is a 50A ANS bolt-down strip fuse for high-current 12V and 24V automotive and marine circuits.
What is the voltage rating?
32V DC. It is suitable for 12V and 24V systems when installed in an appropriate ANS holder or block.
Where should I mount an ANS fuse in the system?
Install the ANS holder as close to the battery or power source as practical to protect the entire cable run from short circuits.
Does an ANS fuse fit MIDI, ANL or blade holders?
No. ANS is a specific bolt-down footprint and requires an ANS compatible holder or distribution block.
What size loads suit a 50A ANS fuse?
Typical uses include mid-power inverters, DC distribution feeds, audio amplifiers and accessory circuits that specify 50A protection. Always follow the equipment manufacturer’s rating.
How do I choose the correct fuse rating for my cable size?
Fuse to protect the smallest cable in the circuit. Select a fuse value at or below the continuous ampacity of that cable and appropriate for the device’s inrush and running current.
What if a new 50A fuse blows again soon after replacement?
Do not upsize. Repeated operation indicates a fault or overload. Inspect for short circuits, undersized cable, damaged insulation or incorrect equipment settings.
Is there a correct orientation when installing an ANS fuse?
ANS fuses are non-directional electrically. Install with clean, flat contact surfaces and tighten the holder hardware securely for low resistance connections.
How many fuses are in the pack and what is the warranty?
Pack quantity is 1. Warranty is 12 months.
What holders and blocks are compatible with Narva 53806?
Use Narva ANS in-line holders or ANS-capable distribution blocks. ANS fuses do not fit blade, MIDI or ANL holders.
