What is the difference between thermal fuse and MOV and polyfuse.Which is faster and also which companies produce polyfuse, especially in Asia.
I have to search for a component that can save my circuit which is connected via a TRIAC to a submersible motor. In it may happen that the live and gnd wires may touch due to rupturing of the overhead seal. This would send a surge that cant be handled by TRIAC. A fast fuse is a temporary solution which has to be changed everytime, so i wanted to ask if Polyfuse was viable in its place.
