OEX Mega Fuse 40A Bolt On Pack Of 5 ACX6518

The OEX Mega Fuse, part number ACX6518, is a bolt-on fuse rated at 40A and designed for 32V DC circuits. It is supplied in a pack of 5, which suits workshop use, fleet servicing, or keeping matched spares on hand for repeat electrical repairs.

This is a Mega fuse with SF51 type construction and copper tin plated contacts. The mounting centres are 50.8mm centre to centre, and the fuse length is 68.5mm, so the physical size and fixing points should be checked carefully before purchase.

If you are replacing an existing bolt-on Mega fuse, the key checks are the current rating, voltage rating, mounting spacing, and the part number ACX6518. Those details matter more than the general fuse style when you are matching an electrical component correctly.

Application and Buying Notes

Before ordering, compare the existing fuse against the OEX ACX6518 by part number, amp rating, and physical dimensions. The important matching points here are 40A, 32V DC, the Mega fuse format, and the 50.8mm centre-to-centre mounting spacing.

The fuse is 68.5mm long and uses a bolt-on arrangement, so it is not enough to rely on the fuse being described as a Mega fuse. Applications can vary by fixing layout, spacing, and circuit design, so the mounting centres should be measured rather than assumed.

Copper tin plated contacts are specified for this fuse, which is useful when you are comparing like for like with a replacement unit. If the original fuse uses a different terminal style, different spacing, or a different current rating, it should not be treated as a direct match.

The pack of 5 is practical where several identical fuses are used, or where you want to keep spares available for the same 40A circuit. For a single replacement option, the same product is also available separately under ACX6518BL.

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 ACX6518 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, 40A Bolt On - Pack of 5. Part number ACX6518 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number ACX6518, 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 matching the part number ACX6518, the 40A rating, 32V DC specification, and the 50.8mm centre-to-centre mounting spacing before purchase.
