    Fuses

    Fuses are safety devices used in an electric plug or circuit, made of a wire component inserted in a non-combustible housing. Their function is to prevent the damages induced by an overflow of electrical current, by overheating and melting the wire inserted in the housing whenever there is a fault, consequently interrupting the electrical flow.

    What are fuses used for?

    An everyday example of fuse applications is represented by hairdryers: when the power flowing in the appliance exceeds the value that should be transferred through it, the fuse within the system makes the circuit break, thus eliminating the risk of shortcuts and electrocution. Fuses are also an essential of every household's electrical system, in form of control board panels (also called fuse boxes or consumer units) which shut the electrical system down in case an over-current that might cause damage is detected.

    What is the difference between a fuse and a circuit breaker?

    Fuses and circuit breakers cover the same safety function in an electrical circuit when there is a risk for over-current. They both interrupt the electrical flow when a fault is detected, but while fuses only work once and have thus to be replaced, circuit breakers can be reset without the need for their substitution.

    Different types of fuses

    Although the most commonly known is probably the cartridge type, there are several other kinds of fuses available on the market for different applications, including:

    • Tag Fuses
    • Square Body Fuses
    • Bottle Fuses
    • Car Fuses
    • Resettable and Non-Resettable Fuses
    • Thermal Fuses

    Cartridge type fuses

    Cartridge fuses can come in form of glass fuses, as well as ceramic or porcelain. They are relatively easy to change and come in different standard ratings you can choose from. To select the right rating the rule of thumb is to select a rating that is slightly higher than the one needed by the device to function. This will allow for the fuse to prevent damage when the voltage gets too high, without the need for switching off the electrical power in conditions of slight, harmless, power enhancement.

    Fuses are also available in kits to cover various uses beyond industrial appliances, such as the fuse kits available from the RS Pro range.
