OEX ACX6505 Midi Fuse 50A Bolt On - Pack of 10

OEX ACX6505 50A MIDI Fuse Pack of 10 SF30 Bolt-On Copper Tin-Plated Element Window 32V DC

The OEX ACX6505 is a pack of 10 bolt-on MIDI fuses rated at 50A and 32V DC in the SF30 form factor. Copper construction with tin-plated finish for corrosion resistance. Each fuse features a visible element window for quick visual inspection of fuse condition without removal from the holder. Compatible with the OEX ACX6514 single MIDI fuse holder and other SF30-format holders. 30mm centre-to-centre bolt mounting, 41mm length. Single-unit variant available as ACX6505BL. One year warranty.

Product overview

The ACX6505 provides reliable overcurrent protection for high-current circuits including dual battery feeds, amplifier power supplies, winch circuits and auxiliary accessory wiring. The MIDI fuse is a bolt-on medium-current format designed for sustained high-current loads, larger than a standard blade fuse and suited to main circuit protection rather than individual accessory circuits.

The visible element window is a practical advantage in hard-to-access installations such as battery boxes, underbonnet fuse panels and enclosed wiring runs, allowing fault diagnosis without removing the fuse from the holder. The 32V DC rating covers both 12V and 24V automotive systems. Fuse selection should match the cable gauge and continuous current draw of the circuit being protected a 50A fuse should be paired with cable rated to carry at least 50A continuously. If unsure of the correct rating, consult a qualified auto electrician before fitting.

Features and benefits

50A circuit protection: Overcurrent protection for dual battery feeds, amplifier power supplies, winch circuits and high-current auxiliary wiring at or below 50A.

Fuse element window: Transparent window built into the fuse body for visual inspection of fuse condition without removal from the holder.

Copper tin-plated construction: Tin plating over copper resists corrosion at the contact surfaces, maintaining low contact resistance in humid, coastal and marine environments.

32V DC rated: Suits both 12V and 24V automotive, commercial and heavy vehicle electrical systems.

SF30 form factor, 30mm centre-to-centre bolt mounting: Standard MIDI fuse mounting pitch compatible with the OEX ACX6514 and other SF30-format MIDI fuse holders.

Pack of 10: For workshop stock, multi-circuit installations and fleet vehicle builds. Single-unit variant available as ACX6505BL.

One year warranty: Covered by a one year OEX warranty.

Frequently asked questions

What is a MIDI fuse and where is it used? A MIDI fuse is a bolt-on medium-current fuse used in automotive, caravan and marine electrical systems for circuit protection in applications such as dual battery setups, amplifier power feeds and winch wiring. It is larger than a standard blade fuse and designed for sustained high-current loads.

What does the fuse element window do? The element window is a transparent section in the fuse body that allows visual inspection of whether the fuse element has blown without removing the fuse from its holder. Useful for quick fault diagnosis in hard-to-access locations such as battery boxes and enclosed fuse panels.

Is this fuse compatible with the OEX ACX6514 MIDI fuse holder? Yes. The ACX6505 uses the SF30 form factor and 30mm centre-to-centre bolt mounting, compatible with the OEX ACX6514 single MIDI fuse holder and other SF30-format MIDI holders.

What is the difference between the ACX6505 and the ACX6505BL? The ACX6505 is sold as a pack of 10, suited to workshop stock and multi-circuit builds. The ACX6505BL is the same fuse sold as a single unit, suited to individual replacement or single-circuit installations.

Is 50A the right fuse rating for my application? Fuse selection depends on your cable gauge and the continuous current draw of the circuit. A 50A fuse should be paired with cable rated to carry at least 50A continuously. If unsure of the correct rating for your installation, consult a qualified auto electrician before fitting.
