Ceramic Fuse Types

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 fuse types.

A glass body cartridge style fuse that is 1 4 in diameter and 5 8 in length. Lucas type fuses are used in old british made or assembled automobiles. Blade type and bolted type. Ceramic fuses serf semi enclosed re wireable fuses are old school forms of electrical protection for a home.

They re used with glass fuses for protecting low current circuits or ceramic fuses for protecting high current circuits. The largest size fuse shown in the chart is the 5ag. The physical length of the lucas ceramic type of fuse is either 1 inch or 1 25 inch with conical ends. The fuses that protect individual 120 volt circuit are typically ceramic screw in plugs that fit into threaded sockets in the fuse panel.

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. Blade type fuses are also known as plug in type fuses. 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. Lucas type fuses usually use the same color coding for the rated current.

Striker types of fuses. 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 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. Usually the body of the fuse is made up of porcelain or ceramic and the fuse element chamber is filled with silica sand.

In bolted type fuse plates of this fuse are conducting are set to the base of the fuse. The knife type fuse or plug in type of fuses is designed with plastic. Ceramic or a similar material other than glass. A ceramic body axial leaded subminiature fuse that is 2 3mm in diameter and 8mm in length.

There are two types of hrc fuses. 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. This type of fuse can be simply changeable in the electric circuit exclusive of any load. These are the sort where you run fuse wire around some screws usually in the dark while holding a torch.

Lucas glass tube fuses have straight ends.
