Narva Standard Blade Fuse 40A Pack Of 50 – Part No. 52840

The Narva Standard Blade Fuse 40A is a standard blade fuse supplied in a pack of 50, with Part No. 52840 and an orange body colour. It is listed as a 40A fuse and is sold as each unit within the pack, which makes it suitable for replacing multiple identical fuses in vehicles or electrical accessory installations that use standard blade fuse sizing.

As a fuse, its job is to protect the circuit by opening when current demand exceeds the rated 40A. That makes the amperage rating the key detail to confirm before fitting. Choosing the correct fuse rating matters because a fuse that is too low may fail unnecessarily, while one that is too high may not provide the intended circuit protection.

This Narva fuse sits in the AUTO ELEC ACCESSORIES group and is classed under FUSES BREAKERS RELAYS SWITCHES. It weighs 0.105kg and carries a one year warranty, which may be useful when ordering for workshop stock, fleet maintenance, or keeping a set of spares on hand for standard blade fuse applications.

Application and Buying Notes

Before ordering, confirm that your application takes a standard blade fuse and that the circuit calls for a 40A rating. The part number, 52840, and the orange colour identification are both useful checks when comparing against the fuse currently fitted or the specification listed for the circuit.

Fuses should always be matched to the correct amperage for the protected circuit. A 40A fuse is not interchangeable with a lower or higher rated fuse unless the vehicle or accessory manufacturer specifically calls for that rating. If the vehicle uses a different blade fuse style or a different fuse size, this part will not be the right match even if the amperage appears close.

The pack of 50 is practical where multiple replacements are needed, or where workshop stock is preferred for commonly used fuses. If you are maintaining a fleet, accessory installs, or a general electrical spares kit, having the same 40A standard blade fuse on hand can save time when a circuit needs attention.

Because fitment details are not listed here, it is best to verify the fuse type, rating, and any application notes before purchase. A simple visual check of the existing fuse and the circuit specification is usually the safest way to confirm whether this Narva 40A fuse is suitable.

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 52840 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 Standard Blade Fuse 40A 50 Pce. Part number 52840 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 52840, 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.

Compatibility note: Confirm compatibility by matching the standard blade fuse type, 40A rating, and Part No. 52840 against the vehicle, accessory, or holder specification before ordering.
