1.Lower residual voltage:it can avoid large residual voltage produced by the fuse itself and coil of connector conductors when the fuse is mounted separately.The effective reduction ratio of residual voltage may be 50% above.

2.More fast response:nanosecond response speed,the max response time is lower than 25ns ,the entire characteristics may be improved in all respects.

3.Convenient installation:it uses the 35mm standard guide rail installation mode,the compact volume guarantees the university of mounting range,more saving space and less installation cost of distributioncabinet.

4.Advantage of N position:No matter which circuit discharges the lightning current,the path is the shortest,thus,the residual voltage is further lowered.

5.In addition.it has the warm-backup double-chip product,9 series LY1-C40 warm-backup lightning-protection module provides the better protection,Therefore,LY9-(D,C,B) series product is the simplified and upgrading product whose performance is improved.

Product Description:

LY9-(D,C,B ) series fuse combination type power supply SPD has the built-in short-circuit protection device,dispensing with the fuse or circuit breaker, it is simplified, superior to the similar products.
