Replacing Your Fuse? Here Is Your Guide

Fuse gives protection to your electronic and electrical devices. Once a fuse in used, it must be replaced right away. This comes in a large main electrical service equipment or a small glass tube. These are generally rated on its size, interruption speed, and voltage it can handle. Whether you’re looking for a fuse for new application or replacement, here are some essential things you must keep in mind.

No. 1 – Before you purchase a new fuse, make sure to know the voltage type to be protected. Fuses are rated by the voltage amount and whether its an alternating current or direct current. But, there are also fuses which can handle both AC and DC power. However, these ratings aren’t the same when it comes to the overall power to be used for protection. So, make sure to pick a fuse that has the correct voltage range of the circuit.

No. 2 – The next thing to determine is the electrical circuit’s amperage which should be protected by the fuse. Wire coil windings are used in fluorescent lighting or motor lighting. These wire coils will have a current inrush once started. Choose a fuse that has a time delay rating or specially manufactured for motor starting. With this, you can be sure that the electrical load gets protection while the overall interruption rating of the fuse is exceeded by the inrush current.

No. 3 – Make sure to determine the size of the fuse holder. Some fuse holders will only connect to certain type of fuses. These fuse connection points are made to fit a specific space and the characteristics of the fuse. For instance, the small glass tube fuse should also be replaced with the same kind. When it comes to the time delay fuse, it has a particular length and diameter. Fuses of different types which may have the same rating and voltage will not suit in that holder. You can’t also replace a less capability fuse for a fuse that handles high amperage and voltage like the large knife blade fuse.

No. 4 – Another important factor to consider is the internal element replacement. There are fuses which has an internal element replacement. You can withdraw these pieces from the cylindrical container once they have blown. And in the round cartridge, the metal fuse strip is put back. After, the circuit is reset for power. Basically, the fuse elements are available in different boxes and rated similarly to a one-time fuse.

No. 5 – Finally, you should pick a fuse with an inspection window. The use of these windows is to show whether the fuse has blown or not. Whether its for home setting or industrial applications, this type is very helpful. You just have to check it from time to time in order to identify any issues with the electrical circuits.

So, these are the different things that you need to look into when replacing your fuse. Now, you are ready to purchase the right fuse for your use.
