SPD Surge Protective Device 1P to 4P

SPD is the range of devices for discharging induced transient overvoltages, in accordance wth EN/IEC 61643-11. DIN rail plug-in format. Ability to discharge induced voltage surges. For very fine protection of sensitive equipment. Installation downstream of type 2 protection. Suitable as the final stage of protection in panels with Type 2 protection devices installed upstream. The residual voltage left downstream is less than for Type 1 or 2. They should be installed as close as possible to the equipment being protected.

GACIA’s system expansion devices includes a wide range of products, helping you build a complete and safe low-voltage electrical system with greater flexibility, stronger protection, and easier integration.
