Selection and Fitment Tips
- Choose fuse vs breaker: Use fuses for simple, low-cost protection. Use plug-in breakers for frequent access or when resettable protection is preferred.
- Size correctly: Each position’s fuse or breaker must protect the smallest cable in that circuit and suit the accessory’s inrush and running current.
- Placement: Mount in a protected location away from direct spray, heat and vibration. Provide strain relief and service access.
- Terminations: Use quality lugs and torque hardware to spec for low resistance, reliable connections.
- Troubleshooting: Repeated operation indicates a fault. Inspect for shorts, damage or overload rather than upsizing protection.
Why Choose Narva 54450?
It consolidates up to twelve accessories into one organized hub and gives you the flexibility to run either conventional fuses or plug-in breakers per circuit, keeping installs clean and future service simple.

What protection devices does Narva 54450 accept?
Each of the 12 positions accepts either a standard blade fuse (ATO/ATC, ATS) or a compatible plug-in type circuit breaker.
Is the block suitable for 12V and 24V systems?
Yes. It is rated 32V DC and suits both 12V and 24V applications when correctly sized and installed.
How should I choose between a fuse and a plug-in breaker for each circuit?
Use a fuse for simple, low-cost protection. Choose a plug-in breaker if you want quick resets or anticipate frequent access for maintenance.
What current rating can each position handle?
Per-position capability depends on the selected fuse or breaker and the wiring. Size protection to the smallest cable in that circuit and stay within the block’s bus and input limits.
Does the block include fuses or breakers in the pack?
Typically supplied as the holder only. Fit standard blade fuses or compatible plug-in breakers to suit each circuit requirement.
Where should I mount Narva 54450 in my setup?
Mount in a protected location with good strain relief and access for service. Avoid areas with direct spray, excessive heat or vibration.
Any wiring tips for low resistance and reliability?
Use quality lugs, keep contact faces clean and flat, torque hardware to spec and recheck fasteners after initial run-in.
How do I size the protection correctly for each circuit?
Match the fuse or breaker to the accessory’s inrush and running current, but never above the continuous ampacity of the smallest cable in that circuit.
What should I check if a circuit repeatedly trips or blows a fuse?
Do not upsize the protection. Inspect for shorts, damaged insulation, incorrect cable gauge or an overcurrent device before refitting the correct value.
What is the warranty and what comes in the pack?
Warranty is 12 months. Pack includes one 12 way standard blade fuse or plug-in breaker block.
