When it comes to protecting electrical circuits, fuses play a crucial role. But with so many options available, why should you consider a Screw Type Fuse instead of blade, cartridge, or resettable fuses? As an electrical engineer with over two decades of experience, I’ve seen firsthand how the right fuse can prevent equipment damage, reduce downtime, and improve safety. Today, I’ll break down the key advantages of Screw Type Fuses and explain why they might be the best choice for your application.
Unlike blade fuses that simply plug in or cartridge fuses that require holders, Screw Type Fuses secure directly into a threaded socket. This design offers several unique benefits:
Stronger mechanical connection – No risk of vibration loosening the fuse.
Better heat dissipation – Metal-to-metal contact improves thermal performance.
Higher current ratings – Ideal for industrial and heavy-duty applications.
Easier to inspect – Visible fuse element allows quick status checks.
But how do these advantages translate into real-world performance? Let’s compare them to other common fuse types.
To help you make an informed decision, here’s a quick comparison:
Feature | Screw Type Fuse | Blade Fuse | Cartridge Fuse | Resettable Fuse |
---|---|---|---|---|
Installation | Screw-in | Plug-in | Holder needed | Snap-in |
Vibration Resistance | High | Low | Medium | Medium |
Current Range | Up to 30A | Up to 40A | Up to 600A | Up to 5A |
Reusability | No | No | No | Yes |
Cost | Moderate | Low | High | High |
As you can see, Screw Type Fuses excel in environments where stability and durability matter most—such as industrial machinery, HVAC systems, and automotive applications.
At Zhenghao, we engineer our Screw Type Fuses to meet the highest safety and performance standards. Here are the critical parameters of our top-selling models:

Our fuses are designed for long-term reliability, ensuring your equipment stays protected even under harsh conditions.
If you’re working with any of the following, a Screw Type Fuse is likely the best choice:
✔ Industrial control panels – Where vibration resistance is critical.
✔ Power distribution units – Needing stable, high-current protection.
✔ Older electrical systems – Designed for screw-in fuse compatibility.
✔ Marine and automotive applications – Where moisture and movement are factors.
Unlike blade fuses that can wiggle loose or cartridge fuses requiring extra hardware, Screw Type Fuses stay securely in place.
Choosing the right fuse can mean the difference between smooth operation and unexpected failures. At Zhenghao, we’ve spent years refining our Screw Type Fuses to deliver unmatched reliability. Whether you’re upgrading an old system or designing a new one, we have the right solution for you.
