What is a Fuse?
A fuse prevents overheating and fire hazards by interrupting excessive current flow.
When too much current flows through the circuit, the fuse element melts, thereby disconnecting the electrical supply.
Fuses are commonly used in consumer electronics, automotive applications, power supplies, and industrial equipment.

What is a Fuse Link?
Essentially, it is the conductor inside the fuse that performs the interrupting function.
The modularity of fuse links makes them a cost-effective option in high-use systems.
The shape, melting point, and size of the fuse link determine its speed and rating.

What Makes DC Fuse Links Special?
Direct current circuits present unique challenges, and DC fuse links are built to manage them safely.
In a DC system, once an arc starts, it is harder to extinguish than in AC systems where the current naturally passes through zero.
These fuses must comply with standards such as UL 248 or IEC 60269-6 for DC protection.

EV Fuse: Power Protection for Electric Vehicles
EV fuses are designed to protect components like battery packs, inverters, and charging systems.
These fuses must tolerate harsh environments, rapid temperature changes, and high current surges.
Standards such as ISO 8820 and SAE JASO guide the design and application of EV fuses.

Choosing the Right Fuse Link
Choosing the right fuse requires evaluating system voltage, expected current, and response speed.
Fuse links are available in fast-blow and time-delay types to match transient or continuous load types.
Some environments may require waterproof or vibration-resistant fuse designs.
