OEX Mega Fuse 250A Bolt On Single Pack 32V DC SF51 Part No. ACX6527BL

The OEX Mega Fuse 250A Bolt On is a single-pack fuse rated at 250A and 32V DC, supplied as part number ACX6527BL. It is a Mega fuse of type SF51 with a bolt-on mounting style and centre-to-centre spacing of 50.8mm, so the physical mounting points matter as much as the current rating when checking replacement suitability.

This fuse is copper tin plated and measures 68mm in length. Those details are useful when comparing it against the original part in an electrical system, because a correct amperage rating alone does not confirm that the fuse will physically match the holder or busbar arrangement.

OEX lists this item as a single pack, with a pack quantity of 1 and a one year warranty. It is also noted as being available in a pack of 5 under ACX6527, which may be useful for workshop or fleet use where the same 250A Mega fuse is required more than once.

Application and Buying Notes

Before ordering, confirm the replacement fuse is also a 250A Mega style unit and that the holder uses a bolt-on arrangement with 50.8mm centre-to-centre mounting. The length of 68mm and the SF51 type are both useful checks when matching against an existing fuse or service part.

This fuse is rated at 32V DC, so voltage rating should be considered alongside the rest of the electrical setup. If the application calls for a different fuse style, different mounting centres, or a different amperage, do not substitute it on the basis of appearance alone.

Part number matching is the safest way to buy electrical components like this. ACX6527BL is the listed part number for the single pack, while ACX6527 is the pack of 5 reference. If you are replacing an existing fuse, compare the original part number, physical dimensions, mounting spacing, and current rating 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 ACX6527BL 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, 250A Bolt On - Single Pack. Part number ACX6527BL should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number ACX6527BL, 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: Please confirm fitment by checking the part number, fuse type, 250A rating, 32V DC specification, 68mm length, and 50.8mm mounting centres against the existing component or vehicle application details before ordering.
