OEX Mega Fuse 500A Bolt On Pack Of 5 ACX6529

The OEX Mega Fuse 500A Bolt On Pack of 5 is a 32V DC fuse pack with a 500A rating, Type SF51 construction, and copper tin plated contacts. It is listed under part number ACX6529 and supplied as a pack quantity of 5, which suits buyers replacing multiple identical fuses or keeping matched spares on hand.

Each fuse measures 68.5mm in length and uses a bolt-on mounting layout with centre to centre spacing of 50.8mm. Those dimensions matter when checking whether the fuse will physically suit the existing holder, busbar arrangement, or electrical assembly before purchase.

This is an OEX Mega Fuse, which is a high-current automotive electrical component intended for applications where the holder and circuit design call for a 500A fuse. The product is supported by a one year warranty, and a single-pack version is also available under ACX6529BL if only one fuse is required.

Application and Buying Notes

Before ordering, confirm the fuse holder is designed for a Mega style bolt on fuse and that the mounting centres match the listed 50.8mm centre to centre spacing. A fuse can share the same current rating and still not suit the physical mounting arrangement, so the 68.5mm length and bolt-on layout should be checked against the existing installation.

The 500A rating and 32V DC specification are the key electrical limits to verify. This fuse should only be used where the circuit, holder, and application are specified for that rating. If the vehicle or equipment uses a different amperage, a different fuse style, or a different voltage requirement, this part is not the correct choice.

The pack quantity of 5 is useful where several identical fuses are needed, or where the workshop wants matched spares for a known application. If only one fuse is required, the separate single pack listed as ACX6529BL may be the more practical option. Always compare the part number ACX6529 with the existing fuse or parts record before buying.

Copper tin plated construction is a useful detail when you are comparing replacement parts, but it does not replace a proper fitment check. The safest approach is to verify the fuse type, mounting centres, length, current rating, and part number together, particularly on high-current electrical systems where the wrong fuse can delay repairs or lead to repeat failures.

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 ACX6529 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, 500A Bolt On - Pack of 5. Part number ACX6529 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number ACX6529, 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 part number ACX6529, Mega fuse style, 500A rating, 32V DC specification, 68.5mm length, and 50.8mm centre to centre mounting before purchase.
