The vertical PCB mount blade fuse holder is a heavy-duty through-hole fuse base designed for standard MAXI blade fuses. This vertical PCB mount blade fuse holder adopts high-temperature PA9T insulating housing with high-conductivity brass terminals, delivering stable electrical connection and reliable overcurrent protection for through-hole printed circuit boards. Widely used in automotive electronics, industrial power supplies, new energy auxiliary systems and high-current PCB modules, it features excellent heat resistance, firm fuse retention and consistent batch performance.
Key Features of Vertical PCB Mount Blade Fuse Holder
- Compatible with standard MAXI size blade fuses, the mainstream high-current automotive blade fuse specification
- Base material: PA9T engineering plastic, black color, high temperature resistance and excellent mechanical strength
- Fuse clip material: 0.4mm thick brass with tin-nickel plating, low contact resistance and strong corrosion resistance
- Vertical through-hole PCB mounting, stable structure, suitable for wave soldering and manual soldering
- Firm clamping force, prevents fuse loosening under vibration and mechanical shock conditions
- High insulation performance, adapts to harsh industrial and vehicle engine compartment environments

Selection & Application Guide
When selecting a vertical PCB mount blade fuse holder, first confirm the fuse size, system rated voltage and working current, as well as the assembly process. For high-vibration and high-temperature scenarios such as automotive and engineering machinery, PA9T housing with brass tin-nickel plated terminals is recommended for better heat resistance and mechanical strength. Always match the MAXI blade fuse rating with the actual working current of the circuit, reserving a 1.25-1.5 times safety margin to avoid premature failure or insufficient protection. The vertical through-hole design ensures stable soldering and easy manual replacement in post-maintenance.
Application Scenarios
- Automotive electronics and new energy vehicle auxiliary circuits
- Truck, bus and commercial vehicle power distribution systems
- On-board chargers and DC-DC converter protection
- Industrial control power supplies and high-current PCB modules
- Telecom base stations and communication power equipment
- Marine and yacht DC power protection systems
- Engineering machinery and heavy equipment electrical systems
Installation & Usage Notes
1. Select a matching MAXI blade fuse with appropriate current and voltage rating before installation.
2. Ensure proper soldering quality during through-hole installation to avoid cold solder joints that cause increased contact resistance and overheating.
3. Insert the fuse vertically into the holder to ensure full contact and firm clamping, preventing loosening under vibration conditions.
4. Do not use the fuse holder beyond its designed current and voltage range to prevent insulation breakdown and safety hazards.
5. Disconnect power before replacing the fuse to avoid electric shock and short-circuit damage.
6. Regularly check the contact position for oxidation and loosening, especially in humid and corrosive environments.
