Narva Fuse Box Standard Blade 12 Way 120A 32V DC Part No. 54450BL

The Narva Fuse Box Standard Blade 12 Way 120A is a 1-piece fuse box designed for standard blade fuses, with a maximum of 12 fuse positions and a total block rating of 120A at 12V. It carries Part No. 54450BL and is supplied as an EACH unit, making it a practical choice where a tidy, centralised fuse distribution point is required.

Key electrical limits are clearly defined: 30A maximum per circuit at 12V, 120A maximum per block at 12V, and 32V DC maximum voltage. Those figures matter when you are matching the fuse box to the intended accessory load, wiring layout, and operating system voltage. The unit is also described as suitable for ATS blade fuses and plug-in circuit breakers.

The housing includes a lockable transparent cover, dual power input terminals, multiple earth returns, and a single grounding terminal. Overall size is listed at 165 x 95mm, and the unit weighs 0.399kg. For installers and buyers comparing compact fuse distribution options, those dimensions and connection points are useful checks before finalising a mounting location.

Application and Buying Notes

Before buying, confirm that your application uses standard blade fuses and that the accessory load for each circuit stays within the stated 30A at 12V maximum per circuit. The overall block rating is 120A at 12V, so the total connected load and upstream protection need to suit that limit as well.

The 12-way layout is useful where several accessories need individual fused protection in one tidy location. Check that the available mounting space can accommodate the 165 x 95mm body, and allow for safe access to the lockable transparent cover, cable entries, and connection points during installation and future servicing.

Electrical compatibility is just as important as physical fit. This unit is listed for 32V DC maximum voltage and includes dual power input terminals, multiple earth returns, and a single grounding terminal. Those details should be matched to the vehicle or system wiring plan, particularly if you are replacing an existing distribution block or integrating additional accessories.

The fuse box is suitable for ATS blade fuses and plug-in circuit breakers, which gives you flexibility when selecting protection devices. Even so, the fuse and breaker choice still needs to suit the circuit design, cable size, and intended current draw. If you are replacing a different style of holder, compare the part number 54450BL, the number of ways, and the connection arrangement before ordering.

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 54450BL 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 12 Way 120A 1 Pce. Part number 54450BL should be checked first. Listed output rating is 120. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 54450BL, 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 120 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.

Compatibility note: Confirm fitment by checking Part No. 54450BL, the 12-way standard blade layout, the 165 x 95mm size, and the 32V DC / 120A electrical limits against your existing installation or intended wiring setup.
