OEX Mega Fuse 500A Bolt On Single Pack Part No. ACX6529BL

The OEX Mega Fuse 500A Bolt On is a single-pack fuse specified at 500A and 32V DC, with a bolt-on mounting style and a centre-to-centre mounting spacing of 50.8mm. It is identified as Type SF51 and is supplied under part number ACX6529BL, making it a straightforward replacement option where those exact details are required.

This is a Mega fuse, not a general-purpose blade fuse, so the physical style and mounting arrangement matter just as much as the current rating. The fuse is copper tin plated and measures 68mm in length, with a listed weight of .01kg. Those details are useful when checking both the fit and the electrical application before purchase.

OEX lists this fuse as a single pack, with an alternative pack of 5 also available under ACX6529. The warranty is one year. For electrical parts like this, matching the part number, amperage rating, voltage rating, fuse type, and mounting spacing is the safest way to avoid buying the wrong component.

Application and Buying Notes

When replacing a high-current fuse such as this 500A Mega fuse, start with the part number ACX6529BL and confirm the fuse type is SF51. The bolt-on layout and 50.8mm centre-to-centre mounting spacing are key fitment checks, because a fuse can have the correct amp rating yet still not suit the holder if the fixing points or physical form differ.

The 32V DC rating is another important checkpoint. That figure tells you the intended electrical environment, so it should be checked against the circuit or application before fitting. The 68mm length is also worth confirming where space is tight, especially in fuse blocks or holders with limited clearance around the mounting area.

The 500A rating is a substantial current value, so this is not a part to choose on appearance alone. A copper tin plated fuse may offer the material specification listed, but the essential buying decision still comes down to matching the required amperage, voltage, mounting spacing, and fuse family. If the old fuse is still available, compare its markings and dimensions directly before ordering.

If you are replacing a damaged or missing fuse, inspect the holder and nearby contacts as well. A fuse can only perform as intended when it is correctly seated and the mating surfaces are in good condition. For best results, confirm the application details from the vehicle or equipment side, then match them to ACX6529BL rather than relying on size or shape alone.

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 ACX6529BL 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 - Single Pack. Part number ACX6529BL should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number ACX6529BL, 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.

Compatibility note: Confirm compatibility by matching part number ACX6529BL, Mega fuse type, 500A rating, 32V DC, Type SF51, and 50.8mm centre-to-centre mounting spacing before ordering.
