The BLACK Electric BSP1-PV40 is a high-performance Type 2 surge protective device (SPD) engineered specifically for DC photovoltaic (PV) systems. Compliant with IEC 61643-31 standards, this SPD offers robust protection for installations operating up to 1000VDC. With a maximum discharge current (Imax) of 40kA and a nominal discharge current (In) of 20kA, it is well-suited for medium to high-risk environments prone to transient overvoltages.
This dual-module SPD features clear status indicators that show green for operational and red when replacement is needed, ensuring ease of monitoring and maintenance. Its compact, DIN-rail mountable design makes it ideal for integration into modern electrical panels without consuming excessive space.
