The DV1-C40PV /3(S) 1500V (D4) Pluggable DC SPD is engineered for advanced surge protection in high-voltage photovoltaic and DC power systems. Designed for sub-distribution board installation, it provides reliable (DC+)–PE and (DC–)–PE protection against lightning-induced and switching surges.

With a nominal discharge current of 20kA (8/20μs) and high-energy MOV technology, it ensures stable, long-term protection in demanding solar environments. The D4 pluggable module design allows quick replacement and minimized downtime.

Compliant with IEC 61643-31 and EN 50539-11 standards (Class I+II / Type 1+2), it is ideal for utility-scale solar plants and large industrial DC installations worldwide.
