Fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current. It is a sacrificial device; once a fuse has operated it is an open circuit, and must be replaced or rewired, depending on its type.
Under rated voltage 1000V, we have FDS-32 and FDS-63 which current under 63A.
All meet IEC 60269-1 and we have TUV certificate.
Breaking capacity is 20KA and operating class gPV for solar protection.
For FDS-32 and FDS-63, Pole is 1P. If customer have special requirements, we can customized if the quantity is big but actual usage is the same with 1P.
It is Din rail installation and link size is 10*38 for 32A and 14*51 for 63A.
For larger current usage, we have FDS-160/250/400/630 as well.
If you need dc fuse in 1500V system, we have FHDS and FDNS series which also have TUV certificate. For this type, max current can be 35A and FEEO is the only manufacturer whose TUV can apply for 35A Fuse.
Q: Do you know the difference between fuse and mcb?
A:They each prevent this from happening over-current through different ways: circuit breakers automatically flip, “breaking” the circuit. Fuses, on the other hand, have a filament that physically melts, preventing the current from continuing to flow. Each one does its job, but they don't work interchangeably for everyone.
