PLUG-TYPE FUSE

PLUG-TYPE FUSE

The plug-type fuse is constructed so that it can be screwed into a socket mounted on a control panel or electrical distribution center. 

The fuse link is enclosed in an insulated housing of porcelain or glass.

The construction is arranged so the fuse link is visible through a window of mica or glass. 

Figure Plug-type Fuse




view A, sows a good plug-type fuse. Notice the construction and the fuse link. 

In figure view B, the same type of fuse is shown after the fuse link has melted. 

Notice the window showing the indication of this open fuse. 

The indication could be either of the ones shown in figure 2-4, view B.

The plug-type fuse is used primarily in low-voltage, low-current circuits. 

The operating range is usually up to 150 volts and from 0.5 ampere to 30 amperes. 

This type of fuse is found in older circuit protection devices and is rapidly being replaced by the circuit breaker.
