Fuse (electrical)
| A miniature time-delay 250 V fuse that will interrupt a 0.3 A current at after 100 s, or a 15 A current in 0.1 s. 32 mm (1 1/4″) long. | |
| Type | Passive |
| Working principle | Melting of internal conductor due to heat generated by excessive current flow |

What is the sign for fuse?
The symbol for a thermal fuse used in any electrical circuit diagram. A thermal fuse is a temperature sensitive switch. It operates on the temperature rather than the current unless the current is sufficient to increase the temperature above the threshold point. This symbol represents a fused switch.
Where do I find the fuse box diagram?
However, sometimes the wire may look intact even in the blown fuse. Fuse box diagrams presented on our website will help you to identify the right type for a particular electrical device installed in your vehicle. Use our website search to find the fuse and relay schemes (layouts) designed for your vehicle and see the fuse block’s location.
How can you tell if a fuse is the correct fuse?
You can verify that you are using the correct fuse, by making sure the fuse colors for the blown fuse and the new fuse match. This indicates the same ampere rating. Make sure to close the fuse box covers properly. It is important to do so to avoid moisture from entering the fuse box. Moisture can cause rust and electrical problems.
When do you need to replace a fuse box?
Inspect a metal strip (fusible element). A damaged one means the fuse has blown. If so, you need to replace it. However, sometimes the wire may look intact even in the blown fuse. Fuse box diagrams presented on our website will help you to identify the right type for a particular electrical device installed in your vehicle.
Why do you need a fuse in a circuit?
Fuses are designed to interrupt the circuit if the circuit current reaches a predetermined force limit. This is necessary to protect components and wires from burnout when an excess current flows through them.

How can I tell if my fuses are constant or switched?
Since the engine is off and the key is out of the ignition, you should be able to probe the fuses and determine which are constant. The constant fuses are the fuses that light up your circuit tester. If you find a combination of both constant and switched fuses in your fuse box – great!
How are constant and switched circuits protected in a fuse box?
Inside your fuse box, these constant and switched circuits tend to live right next to each other, with each circuit protected by an individual fuse. The fuse serves as a “test point” to determine which type of circuit it may be.
