UL listed Type 1CA SPD with high SCCR 200kArms

Product Name: UL listed Type 1CA SPD with high SCCR 200kArms
Application: Power supplies, Telecom, Railway system,PV system, UPS system etc.
Description: SP series SPD is UL1449-4th edition approved SPD. Din-rail designed arc-extinguish SMTMOV ,with window fault indication and optional remote alarm contact. Optional equivalents: OBO V20-C; Phoenix VAL-CP; Dehn DGS(FM);Iskra C(R).


Prosurge SP series surge arrester is UL1449-4th addition approved SPD especially designed for low-voltage power supply system surge protection at the boundaries from lightning protection zone 0B-2 and higher.

It is a din-rail designed surge protective device featuring Prosurge global patent protected TPAE technology design, providing fast and reliable protection for various power supply systems.

Built with special thermally protected MOV with arc-extinguish device, additional window fault indication and optional remote alarm contact, it can monitor the operating status of the surge protector.

It is a very high short circuit current rating of 200kArms, which no need for considering additional over-current protection devices.
