OEX ACX6506BL Midi Fuse, 60A Bolt On - Single Pack

Precise 60A MIDI Fuse Replacement for High-Current Automotive, 4WD, and Caravan Electrical Circuits.

Product Overview

The OEX ACX6506BL is a single bolt-on MIDI fuse rated at 60A and 32V DC, designed for high-current circuit protection in automotive, 4WD, caravan, and marine electrical systems. Sitting at the top of the OEX MIDI fuse range, the 60A rating suits main battery feed protection, high-output amplifier wiring, winch circuits, and dual battery primary connections where lower-rated fuses would be insufficient.

Made from copper with a tin-plated finish for corrosion resistance, the ACX6506BL features a visible element window for non-removal fault diagnosis a practical benefit in enclosed battery boxes and underbonnet fuse holders. Using the SF30 form factor with 30mm centre-to-centre bolt mounting, it is compatible with the OEX ACX6514 MIDI fuse holder and other SF30-format holders. Sold individually as a single unit for replacement or single-circuit applications. A pack of 10 is also available as ACX6506.

Features & Benefits

• 60A High-Current Circuit Protection — The highest rating in the OEX bolt-on MIDI fuse range, the ACX6506BL is suited to main battery feed fusing, high-current amplifier power supplies, winch wiring, and primary dual battery connections where 30A or 50A fuses would be undersized for the load.
• Fuse Element Window — A transparent window in the fuse body allows visual confirmation of blown fuse status without removal — a time-saver during fault diagnosis in enclosed battery boxes, underbonnet panels, and any installation where access is restricted.
• Copper Tin-Plated Construction — Tin plating over the copper element resists contact surface corrosion, maintaining low resistance and reliable current transfer in humid, coastal, and marine-adjacent environments throughout the fuse's service life.
• 32V DC Rated — Covers both 12V and 24V automotive, caravan, and marine electrical systems with voltage headroom, making it suitable across all standard vehicle and off-grid power configurations.
• 30mm Centre-to-Centre Bolt Mounting — Standard MIDI fuse mounting pitch ensures compatibility with SF30-format MIDI fuse holders across the market, including the OEX ACX6514.
• SF30 Form Factor — An industry-standard MIDI fuse format for consistent fitment and easy replacement sourcing from auto electrical suppliers across Australia.
• Single Pack — Ideal for replacing a blown fuse in an existing installation or protecting a single high-current circuit. The pack of 10 variant (ACX6506) is available for workshop stock or multi-circuit builds.

Frequently Asked Questions

What applications is a 60A MIDI fuse suited to?

The 60A rating is suited to high-current circuits including main battery feeds, winch wiring, high-output amplifier power supplies, and primary dual battery connections where lower-rated fuses would be insufficient for the sustained load.

What does the fuse element window do?

The element window is a transparent section in the fuse body that lets you confirm visually whether the fuse has blown without removing it from its holder — useful for fast fault diagnosis in enclosed battery boxes, underbonnet panels, and restricted-access installations.

Is the ACX6506BL compatible with the OEX ACX6514 MIDI fuse holder?

Yes. The ACX6506BL uses the SF30 form factor and 30mm centre-to-centre bolt mounting, which is compatible with the OEX ACX6514 single MIDI fuse holder and other SF30-format MIDI holders.

What is the difference between the ACX6506BL and the ACX6506?

The ACX6506BL is a single-unit pack, suited to fuse replacement or single-circuit protection. The ACX6506 is the same fuse sold in a pack of 10, suited to workshop stock and multi-circuit builds.

How do I choose the right MIDI fuse rating for my application?

Fuse selection depends on your cable gauge and the continuous current draw of your specific circuit. OEX offers 30A (ACX6503), 50A (ACX6505), and 60A (ACX6506BL) bolt-on MIDI fuses to cover a range of automotive and caravan applications. A qualified auto electrician can confirm the correct rating for your installation.
