Product Overview<\/p>\n

A fuse is a switching device that breaks the circuit by melting the fuse element using the
\nheat generated by the device itself when the current exceeds a specified value for a
\ncertain period of time. A drop-out fuse is a type of fuse in which the fuse element
\nautomatically drops out after tripping, thereby creating an open circuit. The RW, HRW,
\nPRWG and HPIRWG series of drop-out fuses are suitable for use in 50 Hz AC power
\nsystems with voltages ranging from 10 kV to 35 kV, providing short-circuit and overload
\nprotection for transmission lines and power transformers.<\/p>\n
