What is the function of drop out fuse?
Drop Out Fuses are protection devices that protect networks and equipment from current surges and overloads. An overcurrent will melt the fuse element in the carrier disconnecting the line or equipment. They also provide network isolation points when manually operated with a hot stick.

How is drop out fuse rating calculated?
Hence motor fuse rating formula,
- For single-phase: Motor fuse rating = PkW x 1.25 / (pf x V(V))
- For Three-phase: Motor fuse rating = PkW x 1250 / (1.732 x power factor x V(V-L))
- Fuse rating Calculation:
- For single-phase:
- For Three-phase transformer,
- Example:
