Selection and Fitment Tips

  • Match amperage: Replace like-for-like at 100A unless the equipment maker 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 to protect the entire cable run.
  • Repeated blows: If a replacement opens again, diagnose wiring faults or overload rather than increasing the fuse rating.

Why Choose Narva 53812?

It delivers dependable, low-resistance protection in a compact bolt-down format, ideal for modern high-current accessory installs where space, efficiency and serviceability matter.

What is Narva 53812?
A 100A ANS bolt-down strip fuse designed for protecting high-current 12V and 24V circuits in automotive and marine systems.
What is the voltage rating of this fuse?
32V DC. Suitable for 12V and 24V applications when installed in an ANS compatible holder or block.
Which holders or blocks are compatible with 53812?
Use Narva ANS holders or distribution blocks such as 54470 and 54472. ANS fuses do not fit blade, MIDI or ANL holders.
Where should I place the ANS fuse in the circuit?
Mount the holder as close to the battery or power source as practical to protect the entire cable run from short circuits.
Typical uses for a 100A ANS fuse?
High draw DC distribution, larger inverters, high-power audio and accessory feeds where 100A protection is specified by the equipment maker.
How do I size the fuse for my cable and load?
Fuse to protect the smallest cable in the circuit. Choose a rating at or below the cable’s continuous ampacity and appropriate for the device’s inrush and running current.
What if the new 100A fuse blows shortly after replacement?
Do not upsize. Repeated operation indicates a fault or overload. Inspect for short circuits, damaged insulation, undersized cable or incorrect settings.
Is there a correct orientation for installing an ANS fuse?
ANS fuses are non-directional. Install with clean, flat contact surfaces and tighten hardware securely for a low resistance connection.
What materials are used in the fuse construction?
Copper alloy element with tin plating and a compact ANS footprint to minimize resistance and allow visual inspection.
How many fuses are in the pack and what is the warranty period?
Pack quantity is 1. Warranty is 12 months.
