Ensure the safety and longevity of your electronic devices with our 20mm Panel Mount Fuse Holder with Cut. This specialized component is designed for professional-grade installations where precision and stability are paramount. Featuring a unique "cut" or flat edge on the threaded body, this holder prevents the unit from spinning during installation or fuse replacement, providing a rock-solid mounting solution.
Anti-Rotation "Cut" Design: The threaded body includes a flat side that fits into a "D" shaped panel hole, preventing the holder from rotating when the cap is tightened or loosened.
Secure Screw-In Cap: Features a robust, finger-grip cap clearly labeled "FUSE" with an arrow indicator for effortless maintenance.
Universal 5x20mm Compatibility: Optimized to house and protect standard 5x20mm glass or ceramic fuses.
Industrial Power Rating: Built to handle standard mains voltages, typically rated for up to 10A 250V AC.
Durable Construction: The high-impact black plastic body and nickel-plated brass hardware offer excellent insulation and corrosion resistance.
Easy Solder Terminals: Equipped with two sturdy solder lug terminals for quick, reliable electrical connections.
This 20mm Fuse Holder is the industry standard for:
Power Distribution Units (PDUs): Providing individual branch protection in server and network racks.
Control Panels: Mounting in machinery where vibration might otherwise loosen standard round fuse holders.
Laboratory Equipment: Protecting sensitive testing gear and power supplies.
Custom DIY Electronics: A favorite for makers building high-quality audio amplifiers or benchtop tools.
Body Type: Threaded with Flat Side (Anti-Rotation).
Fuse Size: 20mm.
Mounting Nut: Included Metal Hex Nut.
Why is the "cut" or flat side important?
Standard round fuse holders can spin in the panel hole if the mounting nut isn't extremely tight. The "cut" locks into a matching panel cutout, ensuring the holder stays perfectly aligned forever.
What size hole do I need to drill?
This holder fits standard industrial "D-hole" cutouts, typically requiring a 12mm to 15mm circular drill bit with one side filed flat to match the body.
Can this be used for DC applications?
Yes, while rated for 250V AC, these holders are commonly used in 12V or 24V DC systems for automotive and solar projects, provided the current does not exceed the 10A limit.
