OEX Midi Fuse 30A Bolt On Single Pack ACX6503BL

The OEX Midi Fuse 30A Bolt On is a single-pack fuse identified as part no. ACX6503BL. It is a Midi fuse rated at 30A and 32V DC, with a centre-to-centre mounting distance of 30mm and a length of 41mm, making the physical mounting details as important as the electrical rating when checking suitability.

This fuse is listed as SF30 and uses a copper tin plated construction with a fuse element window. Those details matter when you are matching the replacement to an existing bolt-on fuse arrangement, especially where the mounting spacing and fuse style need to line up exactly with the original unit.

Pack quantity is 1 and the unit of measure is each. The item is part of the OEX range and carries a one year warranty. For buyers replacing a failed fuse, the key checks are the 30A rating, the Midi type, the 32V DC rating, and the 30mm centre-to-centre bolt spacing.

Application and Buying Notes

When replacing a bolt-on fuse, match the part number ACX6503BL where possible, then confirm the physical format is Midi and the mounting centres are 30mm from hole to hole. A fuse that is the right amperage but the wrong body style or bolt spacing will not be a proper replacement.

The 30A rating is the main electrical checkpoint, but it should only be used where the original circuit calls for 30A. Fitting a fuse with a higher rating than specified can leave the circuit under-protected, while a lower rating can cause nuisance failures. The 32V DC rating is also relevant if you are comparing it to an existing fuse or system specification.

The fuse element window is a useful visual aid for inspection, but it does not replace proper fitment checking. Before ordering, compare the old fuse against the stated 41mm length, the SF30 type marking, and the bolt-on layout. If the fuse is being used as part of a repair, make sure the surrounding fuse holder and terminals are in good condition as well.

A single pack is supplied here, which suits one-for-one replacement work. If you are servicing multiple vehicles or keeping spares on hand, note that this item is also listed in a pack of 10 under ACX6503. Use the item details to choose the pack size that suits the job rather than assuming all Midi fuses are interchangeable.

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 ACX6503BL 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 Midi Fuse, 30A Bolt On - Single Pack. Part number ACX6503BL should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number ACX6503BL, 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 comparing part number ACX6503BL, Midi fuse type, 30A rating, 32V DC rating, 41mm length, and 30mm centre-to-centre mounting before purchase.
