5x20mm na Panghawak ng Piyus na Naka-mount sa Panel | Uri ng Panel ng Piyus na Salamin na 10A 250V

Ang panel mounted fuse holder for 5x20mm glass fuses is a compact panel-installed circuit protection component. This panel mounted fuse holder adopts flame-retardant thermoplastic housing with high-conductivity metal terminals, delivering stable electrical connection and reliable overcurrent protection for various low-voltage AC and DC circuits. With a standard 12.7mm panel cutout and twist-lock structure, it is widely used in industrial control equipment, switching power supplies, household appliances and instrument panels, featuring small footprint, easy installation and stable long-term performance.

Key Features of 5x20mm Panel Fuse Holder

• Compatible with standard 5×20mm glass and ceramic cartridge fuses, the most widely used small fuse specification
• Rated parameters: 10A maximum current, 250V AC/DC rated voltage, covers most low-voltage control and power scenarios
• Housing material: Flame-retardant thermoplastic, UL94 V-0 grade, excellent insulation and high temperature resistance
• Contact resistance ≤ 5mΩ, low power loss, stable electrical performance under long-term operation
• Standard 12.7mm panel cutout diameter, easy to install on equipment panels and control cabinets
• Twist-off cap design, tool-free fuse replacement, convenient for daily maintenance and inspection
• Wide operating temperature range, adapts to industrial and indoor equipment working environments
• UL certified, RoHS compliant, meets global electronic product safety and environmental requirements

Compared with PCB mount fuse holders, this panel type fuse base provides more flexible installation positions and easier front-panel access. Its compact midget design saves valuable panel space, making it especially suitable for compact equipment enclosures and dense control panel layouts.

Pangunahing Teknikal na mga Espesipikasyon

Gabay sa Pagpili at Pag-install

When selecting a panel mounted fuse holder, first confirm the fuse size, system rated voltage and working current, as well as the panel thickness and installation space. For industrial equipment requiring safety certification, UL certified models are recommended to meet market access requirements. Always match the fuse rating with the actual working current of the circuit, reserving a 1.25-1.5 times safety margin to avoid premature fuse failure or insufficient protection. Ensure that the panel cutout size matches the 12.7mm standard diameter to guarantee firm installation and good contact performance. For high-temperature operating environments, derate the current appropriately to ensure long-term reliable operation.

Mga Tala sa Paggamit at Pagpapanatili

1. Drill a 12.7mm diameter hole on the installation panel according to the dimension requirements, and ensure the panel surface is flat and burr-free.

2. Insert the fuse holder from the front of the panel, and tighten the fixing nut from the back to ensure firm installation without loosening.

3. Connect the circuit wires to the rear terminals tightly, and make proper insulation treatment to avoid short circuit risks.

4. Select a matching 5x20mm fuse with appropriate current rating, put it into the holder, and screw on the end cap tightly.

5. Do not use the fuse holder beyond its rated voltage and current range to prevent insulation breakdown and safety hazards.

6. Disconnect the power supply before replacing the fuse to avoid electric shock and short-circuit damage. The twist-off cap allows quick fuse replacement without additional tools.

7. Regularly check the terminals and cap for loosening or oxidation, and replace the product in time if any abnormality is found.
