Application and Buying Notes

Before ordering, confirm the fuse type in the vehicle or equipment is Mega and that the mounting layout matches the 50.8mm centre-to-centre spacing. The part is a bolt-on design, so the terminal arrangement needs to suit the application rather than relying on general fuse size alone.

The 300A amperage rating is the main electrical checkpoint. A fuse should be selected to match the circuit design and the specified protection level for that system. Do not choose a higher rating just because the fuse physically fits, as the current rating is part of the protection function.

The 32V DC rating and SF51 type are important when matching the replacement to the existing part. If you are replacing a fuse already fitted, compare the part number ACX6528BL, the physical length of 68mm, and the centre-to-centre mounting measurement before fitting.

Because no vehicle applications are supplied for this item, the safest approach is to verify the existing fuse details, mounting points and rating on the vehicle or equipment itself. If you are unsure, check the existing fuse markings and mounting style before purchase.

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 ACX6528BL 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.

OEX Mega Fuse, 300A Bolt On - Single Pack. Part number ACX6528BL should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number ACX6528BL, 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 fitment by comparing the part number ACX6528BL, the Mega fuse type, 300A rating, 32V DC rating, 68mm length and 50.8mm centre-to-centre mounting spacing against the existing component or application details before ordering.
