OEX Mega Fuse 125A Bolt On Single Pack – Part No. ACX6522BL

The OEX Mega Fuse 125A Bolt On Single Pack is a Mega type fuse rated at 125A and 32V DC, supplied as one piece for automotive electrical applications where a bolt-on fuse format is required. It carries part number ACX6522BL and uses a centre-to-centre mounting measurement of 50.8mm.

This fuse is listed as Type SF51 and features copper tin plated construction. The length is 68mm and the unit of measure is each, with a packed quantity of 1. Those details matter when you are replacing a fuse in an existing holder or matching a known electrical setup by size and mounting pattern.

As with any power and electrical component, correct identification is essential before ordering. The key checkpoints here are the 125A rating, 32V DC rating, bolt-on mounting style, 50.8mm centre-to-centre mounting, and part number ACX6522BL. If your application does not match those details, it should not be assumed compatible.

Application and Buying Notes

Before buying, confirm that your existing fuse setup is a Mega fuse with bolt-on mounting and that the mounting centres are 50.8mm apart. This product is specifically identified as ACX6522BL, so matching the part number is the safest way to avoid a mismatch, especially where fuse blocks or holders have a fixed bolt pattern.

The 125A rating is the main electrical specification to check. A fuse should be selected to suit the original circuit design and the protected component’s requirements. Do not substitute a different amperage simply because the physical size looks similar, as the 32V DC rating, fuse type, and mounting arrangement all need to line up with the application.

The 68mm length and copper tin plated construction are useful reference points when comparing against an existing part. If you are replacing a blown fuse, check the old unit carefully for the stamped rating and style before ordering. The wrong fuse type, even with the right amperage, may not suit the holder or the intended circuit.

This listing is for one fuse only. If you need spares, note that the same product family is also listed in a pack of 5 under ACX6522. For workshop or fleet use, it is worth confirming whether you need a single replacement or multiple pieces before ordering.

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 ACX6522BL 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, 125A Bolt On - Single Pack. Part number ACX6522BL should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number ACX6522BL, 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 ACX6522BL, the 125A rating, Mega bolt-on style, 32V DC specification, and 50.8mm centre-to-centre mounting before purchase.
