Narva 52505 – Micro Blade Fuse 5A (Box of 25)

Narva • Micro blade fuse • 32V DC rating • Box of 25 • Colour: Orange

Product Overview

The Narva 52505 is a compact 5A micro blade fuse designed for modern automotive and 4WD circuits where space is tight and reliable protection is critical. It uses the micro blade (ATM-LP) form factor with a typical body size of 11 × 9 mm for easy fitment in late-model fuse boxes and low-profile in-line holders. Suited to low-current accessories, ECUs, sensors and lighting control circuits on 12/24V systems, it follows the standard 5A orange colour coding for quick identification.

Common uses include accessory power feeds, communication modules, lighting control, and protection of low-draw electronics. Choose this fuse when you need fast-acting protection in a small footprint with 32V DC system compatibility.

How to Choose the Right Fuse

Match amperage: Replace like-for-like (5A here) unless the vehicle manufacturer specifies otherwise. Oversizing can mask faults; undersizing causes nuisance blows.
Voltage rating: Fuse must be equal to or higher than system voltage - this fuse is suitable up to 32V DC.
Form factor: Use micro blade only in micro slots/holders; mini or standard blade will not fit.
Environment: For under-bonnet or exposed installs, use sealed in-line holders to protect from moisture and vibration.
Circuit behaviour: Fast-acting fuses suit electronics and low inrush loads; for high inrush devices (motors, compressors) size accordingly and consider time characteristics of the circuit.

Why Choose Narva 52505?

It’s a genuine Narva micro blade fuse with the correct 5A orange coding and compact footprint, ideal for modern vehicles and tight fuse panels.

Buying in the 25-pack is cost-effective for workshops and fleets, while the same fuse is also available in a 5-pack for glovebox spares.

What size is the Narva 52505 and will it fit my car?

It’s a micro blade fuse with an approximately 11 × 9 mm body. It fits fuse positions designed for micro blade (not mini or standard) fuses.

What systems can this fuse be used on?

Use on 12V and 24V automotive systems. The fuse carries a 32V DC rating, suitable for passenger, 4WD, marine and equipment applications.

Is the 5A rating the same as the continuous current?

The fuse is designed to protect a 5A circuit. Continuous load is typically kept below the fuse rating to prevent nuisance blows, especially where ambient temperatures are high.

What does the orange colour mean?

Orange is the standard colour for 5A micro blade fuses, helping fast visual identification during diagnostics.

Do I need a special holder for micro blade fuses?

Yes. Use micro blade holders or panels. For in-line installs, Narva 54410BL suits micro blade; to piggy-back a new circuit from an existing slot, use 54411BL.

Can I upgrade to a higher-amp fuse if it keeps blowing?

No. A blowing fuse indicates a fault or an overloaded circuit. Fix the cause or re-size the wiring/components; do not oversize the fuse beyond design limits.

Is this fuse fast-acting or time-delay?

Automotive micro blade fuses are fast-acting. They suit electronics and low-inrush loads; assess inrush if protecting motors or compressors.

What pack sizes are available?

This listing is a box of 25 (52505). The same fuse is available as a blister 5-pack (52505BL) for spares or small jobs.

Where is a 5A micro blade fuse commonly used?

Low-draw accessory feeds, ECU and sensor protection, communication modules, instrument illumination and similar small circuits.

Any installation tips?

Confirm the original fuse rating, inspect for shorts or damaged wiring, use the correct micro blade holder, and seat the fuse fully. For exposed areas, choose sealed in-line holders.
