Technical Features of Fuses
Fuses operate by melting a wire or element when excessive current flows through them, breaking the circuit and preventing damage. Below is a comparison table of the key technical features of fuses:
| Feature | Description |
|---|---|
| Current Rating | The maximum current a fuse can carry without blowing. |
| Voltage Rating | The maximum voltage a fuse can handle before it fails. |
| Breaking Capacity | The maximum fault current a fuse can interrupt without causing damage. |
| Time-Current Characteristic | The relationship between the time a fuse takes to blow and the current flowing through it. |
| Material | Common materials include copper, aluminum, and various alloys. |
| Size | Fuses come in various sizes, including cylindrical and blade types. |
| Mounting Type | Fuses can be panel-mounted, PCB-mounted, or in-line. |
Types of Fuses
Fuses come in various types, each designed for specific applications and environments. The following table outlines the different types of fuses and their characteristics:
| Type | Description |
|---|---|
| AC Fuses | Designed for alternating current circuits, more resistant to electric arcs. |
| DC Fuses | Used in direct current circuits, with specific voltage ratings. |
| Cylindrical Fuses | Basic design, widely used in various applications. |
