Much Ado About Fuses

Posted on: October 7th, 2011 by admin

buying surplus fusesIn the world of electronic components, the fuse is kind of like the guardian angel.  Its job is to protect the power system by preventing too much current from flowing through a circuit, which can lead to overload or failure. Anyone who’s ever overloaded their home circuit before with a hairdryer or other powerful electronic device has probably “blown a fuse.” What’s happening in that case is the fuse has interrupted the overload of power current and prevented damage and possible fire, by shutting down the system.  The fuse dates back to the mid-1800s when it was first invented. It was later patented, with the help of Thomas Edison, as part of the electronic distribution system.


So how does a Fuse work?

A fuse is mounted between electrical terminals and carries the current of power through a protected circuit. If the current of power is too high, the element in the fuse rises in temperature and either melts or joins with the fuse, opening the circuit. When the metal conductor opens, an electric arc is formed between the un-melted ends of the element. The arc grows until the voltage required to sustain the arc is higher than the available voltage in the circuit. Fuse elements are made of alloys with predictable characteristics like aluminum, copper, silver or zinc.

Fuses come in different voltage ratings such as 120V or 230V. The voltage rating has to be the same or larger than the open circuit voltage to work correctly. The International Electrotechnical Commission creates standards that unify a number of national standards of fuses, which help improve the interchangeability, along with the buying and selling of fuses around the world.  In North America, low-voltage fuses to 1kV AC rating are made in accordance Underwriters Laboratories (UL).

Fuse Uses

There are a large array of fuses out there. Thermal fuses are the kind most often found in consumer products like hair dryers, electronic devices and even coffee makers. The thermal fuses are non-resettable devices that cannot be used again once they are “blown”.

Resettable fuses make use of a thermoplastic conductive element that is self-resetting. When the power current is removed, the device will cool and go back to low resistance. These types of resetting fuses are mostly used in computer components so that if a mouse or keyboard shorts, it doesn’t affect the motherboard. Resettable fuses are also often used in the nuclear and aerospace industry.
