Narva Micro 2 Blade Fuse 20A 5 Pack Part No. 52420BL

The Narva Micro 2 Blade Fuse 20A is a yellow blade fuse supplied in a pack of 5, with part number 52420BL. It is a Micro 2 blade fuse type, rated at 20A, and is listed under Narva’s auto electrical accessories range.

This is a small, lightweight fuse at 0.005kg each, intended for vehicle electrical circuits that call for a Micro 2 blade fuse. Because fuse style and amperage are both critical, the 20A rating and Micro 2 format should be matched exactly to the application before fitting.

Each pack contains 5 fuses, which is useful where you want to keep a spare supply on hand for future electrical maintenance. The yellow colour identifies the 20A rating, which is a common visual check when replacing a blown fuse in a compatible fuse holder.

Application and Buying Notes

Before ordering, confirm the fuse holder takes a Micro 2 blade fuse and that the circuit requires a 20A fuse. The part number 52420BL, the Micro 2 blade format, and the yellow 20A colour coding are the main checks to match against the vehicle or equipment specification.

A fuse is not a universal part, even when the amperage appears similar. The physical style must match the fuse slot, and the amperage must suit the protected circuit. Fitting the wrong type can prevent proper seating or leave the circuit incorrectly protected.

The pack quantity is 5, so this suits routine workshop use or keeping spares in the glovebox or parts drawer. If you are replacing a blown fuse, make sure the cause of the failure has been checked before installing another 20A fuse.

For electrical reliability, select the same fuse type and rating that the circuit was designed to use. The Narva Micro 2 Blade Fuse 20A is a straightforward service item, but correct identification matters just as much as the replacement itself.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number 52420BL helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

Narva Micro 2 Blade Fuse 20A 5 Pce. Part number 52420BL should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 52420BL, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a fuse in workshop, fleet, trade, agricultural, or construction service, the listed electrical specification should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

In the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm compatibility by checking the fuse type, 20A rating, and part number 52420BL against the vehicle or equipment application before purchase.
