High voltage fuse for the protection of power capacitor
Categories:High Series   
81
□The specical fuse for high Voltage capacitor: XRNC,BR1,BR2,BRN,BRW2,BR,RN,RNYI,RNGand RW type fuse is used as internal fault protection for single capacitor of star connection capacitor combination in 10KV and less power system. The product can disconnect the fault capacitor reliably and quickly so as to avold explosion accident as a result of component break down inside the capacitor to ensure that the power net operates continuously and safaly.
