OEX ACX6531 Panel Mount Mega Fuse Holder 500A 1 Way Side Connection Entry with Stainless Steel Studs
The OEX ACX6531 is a single-way panel mount mega fuse holder rated to 500A with side connection entry, stainless steel studs and a PA6-GF30 glass-fibre reinforced housing. Short-term temperature rating is 180°C for up to 2 minutes and long-term rating is 100°C for up to 30 minutes. Weighing 0.14kg, it is supplied individually with a one-year warranty. An end/rear connection entry version is also available as the ACX6530.
Product overview
The ACX6531 is the side connection entry variant of the OEX 500A panel mount mega fuse holder, designed for installations where cables approach the fuse holder from the side rather than the rear. The PA6-GF30 glass-fibre reinforced nylon housing provides structural rigidity and thermal resistance suited to demanding automotive and commercial installation environments. Stainless steel studs resist corrosion across marine, underbonnet and outdoor applications.
At a 500A maximum current rating, the ACX6531 suits the most demanding main circuit mega fuse applications in 12V and 24V systems. The thermal specifications 180°C short-term (2 minutes) and 100°C long-term (30 minutes) confirm suitability for high-load and elevated-temperature environments. For installations where cables enter from the rear or end, the ACX6530 is the correct alternative.
Features and benefits
500A maximum current rating: Suited to the most demanding main circuit mega fuse applications including large battery bank feeds, multi-alternator charging systems and heavy commercial power distribution.
Side connection entry: Cables enter from the side of the holder, suited to installations where cable routing approaches from a lateral direction and rear-entry is not practical.
PA6-GF30 glass-fibre reinforced housing: The 30% glass-fibre reinforced PA6 nylon housing provides structural rigidity and thermal resistance beyond standard nylon, suited to demanding installation environments.
Stainless steel studs: Corrosion-resistant stainless steel studs maintain connection integrity in marine, underbonnet and outdoor mounting environments.
Short-term temperature rating 180°C: Handles brief thermal peaks of up to 180°C for up to 2 minutes without housing deformation.
Long-term temperature rating 100°C: Rated for continuous operation at up to 100°C for up to 30 minutes, confirming suitability for high-load environments.
Single circuit: Single-way configuration protects one circuit per holder.
ACX6530 rear/end entry alternative: An end/rear connection entry version of this holder is available as the ACX6530 for installations where cables approach from the rear.
One year warranty: Covered by a one-year OEX warranty.

Frequently asked questions
What is the difference between the ACX6531 and the ACX6530? Both are 500A single-way panel mount mega fuse holders with stainless steel studs. The ACX6531 has side connection entry, routing cables from the side of the holder. The ACX6530 has end/rear connection entry, routing cables from behind or the end. Select based on your cable routing requirements for the specific installation.
What fuses are compatible with the ACX6531? The ACX6531 is a mega fuse holder compatible with standard SF51 type mega fuses. OEX mega fuses in the correct amperage for your circuit are available separately contact us for compatible fuse options.
What does the PA6-GF30 housing material mean for this fuse holder? PA6-GF30 is a 30% glass-fibre reinforced nylon, providing greater structural rigidity and thermal resistance than standard nylon. This makes the ACX6531 housing more resistant to deformation under heat and mechanical stress compared to unreinforced plastic housings.
Is the ACX6531 suitable for marine or underbonnet installation? Yes. The stainless steel studs, 180°C short-term temperature rating and glass-fibre reinforced housing make the ACX6531 suited to both marine and underbonnet environments. Ensure the holder is positioned away from direct heat sources and moving components when installing underbonnet.
How many circuits does the ACX6531 protect? The ACX6531 is a single-way fuse holder protecting one circuit. For multi-circuit applications, multiple units will be required.
