Ceramic Fuse Types

Lucas type fuses usually use the same color coding for the rated current.

Ceramic fuse types.

The physical length of the lucas ceramic type of fuse is either 1 inch or 1 25 inch with conical ends. The knife type fuse or plug in type of fuses is designed with plastic. The largest size fuse shown in the chart is the 5ag. A thin metal strip inside the fuse conducts all electrical flow through the circuit and if the current flow exceeds the current carrying capacity of the metal strip it overheats and melts thereby interrupting the flow of current and shutting off the circuit.

Lucas type fuses are used in old british made or assembled automobiles. They re used with glass fuses for protecting low current circuits or ceramic fuses for protecting high current circuits. The fuses that protect individual 120 volt circuit are typically ceramic screw in plugs that fit into threaded sockets in the fuse panel. Lucas glass tube fuses have straight ends.

There are two types of hrc fuses. In bolted type fuse plates of this fuse are conducting are set to the base of the fuse. The renewable type fuses and automotive fuses appeared in 1914 and in 1927 littelfuse started making very low amperage fuses for the budding electronics industry. These are the sort where you run fuse wire around some screws usually in the dark while holding a torch.

A ceramic body axial leaded subminiature fuse that is 2 3mm in diameter and 8mm in length. Ceramic or a similar material other than glass. This type of fuse can be simply changeable in the electric circuit exclusive of any load. Striker types of fuses.

A 60 volt dc fuse designed for the telecom industry. Blade type and bolted type. Glass and ceramic fuse blocks accept 1 4 x 1 1 4 glass or ceramic fuses for overcurrent protection in electronics equipment appliances and lighting circuits. Fuses at work a current can become corrupted or overloaded due to accidental damage from pets or being moved general deterioration excessive overloading of the electrical system or exposure to the elements.

The types of fuses include long time lag or super time lag tt fast acting fuses ff quick blow fuses f and slow blow or time lag fuses t. Ceramic fuses serf semi enclosed re wireable fuses are old school forms of electrical protection for a home. A glass body cartridge style fuse that is 1 4 in diameter and 5 8 in length. A time delay fuse also known as an anti surge or slow blow fuse is designed to allow a current which is above the rated value of the fuse to flow for a short period of time without the fuse blowing.

These types of fuse are used on equipment such as motors which can draw larger than normal currents for up to several seconds while coming up to.
