Fuse Alarms

Applications

• This series of fuse alarms are used in electric lines of AC50Hz and rated voltage up to 1000V as melting signal/siren for the fuse links

Design Features

• It's 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 micro switch 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 highs.
