Narva Fuse Box Standard Blade 4 Way 30A 1 Pce 54420BL

The Narva Fuse Box Standard Blade 4 Way 30A 1 Pce is a standard blade fuse box rated at 30A per circuit at 12V. It is identified by part number 54420BL and is supplied as a single unit, which makes it a practical option when you need a compact multi-circuit fuse holder rather than a loose fuse assortment.

This fuse box is suitable for lateral connection with female 6.3mm blade terminals. That detail matters when you are checking the terminal style already used in the vehicle or accessory wiring, because the connection method needs to match the existing harness rather than relying on a generic blade fit.

The unit holds 4 standard blade fuses and comes with a transparent cover, gasket and 8 terminals. With a weight of 0.045kg, it is a light electrical accessory, but the key point is the 30A amperage rating per circuit at 12V, which should always be checked against the circuit it is intended to protect.

Application and Buying Notes

Before ordering, confirm that your application uses standard blade fuses and that the wiring arrangement is set up for lateral connection with female 6.3mm blade terminals. The part number 54420BL is the most reliable way to cross-check the item you need, especially where the fuse box position, terminal style, or circuit layout differs between vehicles or accessory installations.

The 4-way layout means this fuse box can carry four standard blade fuses, with each circuit rated at 30A at 12V. That rating is important when you are matching the holder to a circuit, because the fuse box must suit the electrical load and the wiring design it is being installed into. If the intended circuit requires a different current rating, a different fuse holder should be selected rather than forcing this one into service.

As with any electrical component, the safest approach is to verify the part number, fuse type, connection style and amperage rating before purchase. This is especially important where the original fuse arrangement has been modified, where the vehicle has added accessories, or where you are replacing a damaged fuse box with one that needs the same terminal and circuit format.

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 54420BL 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 Fuse Box Standard Blade 4 Way 30A 1 Pce. Part number 54420BL should be checked first. Listed output rating is 30. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 54420BL, 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 box in workshop, fleet, trade, agricultural, or construction service, the listed output 30 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 part number 54420BL, standard blade fuse type, 4-way layout, 30A per circuit at 12V, and lateral connection with female 6.3mm blade terminals before purchase.
