1.Lower residual voltage:it can avoid largeresidual voltage produced by the fuse itself and coil of connector conductorswhen the fuse is mounted separately.The effective reduction ratio of residualvoltage may be 50% above.
2.More fast response:nanosecond responsespeed,the max response time is lower than 25ns ,the entire characteristics maybe improved in all respects.
3.Convenient installation:it uses the 35mmstandard guide rail installation mode,the compact volume guarantees theuniversity of mounting range,more saving space and less installation cost ofdistributioncabinet.
4.Advantage of N position:No matter whichcircuit discharges the lightning current,the path is the shortest,thus,theresidual voltage is further lowered.
5.In addition.it has the warm-backupdouble-chip product,9 series LY1-C40 warm-backup lightning-protection moduleprovides the better protection,Therefore,LY9-(D,C,B) series product is thesimplified and upgrading product whose performance is improved.
ProductDescription:
LY9-(D,C,B ) series fuse combination type powersupply SPD has the built-in short-circuit protection device,dispensing with thefuse or circuit breaker, it is simplified, superior to the similarproducts.
