HRW11A-12L/100(200)-6.3(12.5) AC high-voltage falling type fuse cutout (linkage falling)
Application:
It is used to prevent the short circuit or over load situation of the power transmission and distribution wire or power transformer in the power system of 12kV rated voltage and 50Hz rated frequency.
Characters:
1The falling fuse’s three phases are in same seat and can be separately operated. When one phase failure occurs, the fuse will fall down. Then the fuse will automatically link the other two phases and make them fall down too. Therefore, the transformer and other electronic equipment will not be burnt because of lacking phases.
2 It has good explosion proof ability and strong dirt Resistance ability. Besides, it has small electricity resistance ability, small volume, light weight and good safety reliability.
3 It can be easily installed and used. It can be applied in server weather conditions and dirty environments.
