Electrical Controls for Machines – Fuses There are three types of fuses:Standard one time fuses or a renewable fuse linkTime Delay or dual elementCurrent Limiting Standard fuses usually have a 250V to 600V. You can get higher voltage. They come in ranges from a fraction to 600, you can get these in almost every kind except for the current Limiting. They range from 600v and higher. Your standard fuse has a low temperature metal strip. If the voltage is too high the strip will melt and shut off.The Dual Element is meant to deal with heavy overloads that last for...
