Selection and Fitment Tips

  • Match amperage: Replace like-for-like at 100A unless the equipment maker specifies otherwise.
  • Match the footprint: ANL fuses require ANL holders and will not fit ANS, MIDI or blade holders.
  • Mount location: Install the holder close to the battery or source to protect the full cable run.
  • If it blows again: Diagnose wiring faults or overload rather than increasing the fuse rating.

Why Choose Narva 53910BL?

It delivers reliable, low resistance protection in a proven ANL bolt-down format, ideal for larger accessories and system feeds. The single blister pack suits one-off installs and keeps workshops and gloveboxes stocked with the right value.

What is Narva 53910BL?
A 100A ANL bolt-down fuse supplied in a retail blister 1-pack for protecting high-current 12V and 24V circuits.
What systems is it suitable for?
Automotive and marine 12V and 24V DC systems that specify a 100A ANL fuse in an ANL holder or block.
Does an ANL fuse fit ANS, MIDI or blade holders?
No. ANL is a specific bolt-down footprint and must be used with an ANL holder.
Typical applications for a 100A ANL fuse?
DC distribution feeds, medium inverters, high-power audio amplifiers and accessory circuits calling for 100A protection.
Where should I mount the ANL holder in the circuit?
As close to the battery or power source as practical so the entire cable run is protected from shorts.
How do I size the fuse for my cable and load correctly?
Choose a fuse that protects the smallest cable in the circuit. The rating should not exceed the cable’s continuous ampacity and must suit the device’s inrush and running current.
What if a new 100A fuse blows again shortly after replacement?
Do not upsize the fuse. Inspect for short circuits, undersized cabling, damaged insulation or incorrect device settings before refitting.
Is there a correct orientation for installing ANL fuses?
ANL fuses are non-directional. Ensure clean, flat contacts and tighten the hardware securely for a low resistance connection.
What is included in 53910BL and what is the warranty?
One 100A ANL fuse in a blister pack. Warranty is 12 months.
Any installation tips to reduce voltage drop and heat?
Mount close to the source, select the correct cable gauge, torque terminals to the holder’s spec and keep contact surfaces clean and tight.
