OEX Mega Fuse 300A Bolt On Pack Of 5 - Part No. ACX6528

The OEX Mega Fuse 300A Bolt On pack is a practical option for higher-current automotive electrical circuits where the fuse type, amp rating, and mounting pattern all need to line up. This pack contains 5 fuses, each rated at 300A and designed for 32V DC applications, with a bolt-on mounting style and centre-to-centre spacing of 50.8mm.

The fuse is identified as type SF51 and is copper tin plated. Its length is 68.5mm, which gives you another useful check when comparing against the existing fuse or the fuse holder in the vehicle or accessory circuit. The part number is ACX6528, and a single pack is also available under ACX6528BL if you only need one piece rather than a pack of five.

When replacing a high-amp fuse, the important points are the amp rating, fuse type, voltage rating, mounting centres, and physical size. This OEX Mega Fuse is specified at 300A, 32V DC, with 50.8mm centre-to-centre mounting, so it should be matched carefully to the original setup before purchase.

Application and Buying Notes

Before ordering, compare the existing fuse’s part number, amp rating, and mounting layout against ACX6528. The listed 300A rating, 32V DC rating, and 50.8mm centre-to-centre mounting are the key identifiers here, and they need to match the circuit or holder already in the vehicle or accessory installation.

The 68.5mm length is another practical checkpoint when confirming physical fit. Even where the amp rating is correct, a fuse still needs to suit the holder design and bolt spacing, so it is worth checking the old fuse or the mounting points directly rather than relying on appearance alone.

This is a pack of 5, which suits workshops, fleet maintenance, or buyers who want spare fuses on hand for the same application. If you only need one fuse, there is also a single pack option listed as ACX6528BL. The pack quantity does not change the electrical rating or dimensions, so the same fitment checks still apply.

The copper tin plated construction and SF51 type are useful identifiers when comparing like-for-like parts, particularly where the original fuse has markings or a specific finish that need to be matched. For any high-current circuit, it is sensible to confirm the original fuse specification exactly before replacing it.

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 ACX6528 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 - Pack of 5. Part number ACX6528 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number ACX6528, 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 the part number ACX6528, the 300A rating, 32V DC rating, SF51 fuse type, 50.8mm centre-to-centre mounting, and 68.5mm length against the existing fuse or holder before purchase.
