The system of FSF1 fuse has the quality level with stabilization and consistency. Rated Voltage: 230/400V; Breaking :50KA

The system of FSF1 fuse has the quality level with stabilization and consistency.It's low consumption of the rated power, high economical efficiency, and little fever;high rated interrupting capacity that can be used to break safely and reliably from the smallestunallowedoverload current to the biggest short circuit current; the fine classification ofselective scale makes the best use of conductor cross section; the strong cut-off currentfrequency can reliably protects each part of supply system; it maintains reliable functionin the peren-nial persistent run; the high stability of aging resistance avoids unnecessary operationaltroubles; it can guarantee the stable change of characteristic curve under allsorts of temperature conditions.
