Fuse Alarms
This series of fuse alams are used in electric lines of 50Hz AC and rated voltage up to 1000V as melting signal/siren for the fuse links.

It is made up of the following parts:1.Melt striker;2.Micro switch(with one normal close contact and one normal open contact);3.A base for the striker and the switch.
Fuse alarms are usually paralleled under the lid fastening screws at the ends of the fuse.When the fuse breaks,the striking pin springs out of the striker,the microswitch pushed and signal sent out or circuit cut down.The distance between the two fastening ends can be adjusted in a certain range for paralleling to fuses with different heights.

Models,rated voltage and dimensions are shown in Figure 13.1~13.2and Table 13.
