Panel Mount Fuse Holder: Complete Technical Guide (5×20, 6×30 & 10×38)

A panel mount fuse holder is a front-accessible, flush-mounted socket that secures a cylindrical fuse inside a control panel, enclosure or machine fascia. It is the industry-standard protection component for control cabinets, AC/DC power supplies, battery chargers and industrial automation equipment, allowing tool-free fuse replacement without opening the enclosure.

Construction & Materials

Our holders are built with flame-retardant housings meeting UL94 V-0 and nickel-plated brass contacts for low resistance and high corrosion resistance. This ensures reliable performance at rated current, stable contact under vibration, and safe operation in elevated temperature environments.

Selection Criteria

1. Match the holder to the fuse size (5×20, 6×30 or 10×38) – the holder must fit the fuse diameter and length.
2. Verify rated current & voltage against your circuit requirements.
3. Confirm panel cut-out diameter and mounting style (threaded ring or spring clip).
4. Choose IP rating – IP40 offers protection against solid objects; fully sealed versions are available for dusty environments.

Applications

• Control cabinets and switchgear panels
• AC/DC power supplies and adapters
• Battery chargers and energy storage systems (ESS)
• Industrial machines and test instruments
• Photovoltaic (PV) and inverter systems

Foire aux questions

What fuse sizes fit a panel mount fuse holder?

Standard holders fit 5x20mm glass tube fuses; 6x30mm and 10x38mm cartridge fuse holders are also available.

What is the difference between panel mount and PCB mount holders?

Panel mount holders install into the panel front, while PCB mount holders (fuse clips) solder directly onto a circuit board.

What is the maximum current rating?

5×20 holders typically handle up to 10A, 6×30 up to 16A, and 10×38 up to 40A, depending on voltage rating.

Are the holders flame retardant?

Yes. Housings meet UL94 V-0 flame-retardant standards for industrial safety.

Do you offer custom and bulk orders?

Yes. We support OEM/ODM, custom specifications and bulk supply. Contact us for a quote.
