The DV1-C40PV /3(S) 1000V (D4) Pluggable DC SPD is designed for high-performance surge protection in photovoltaic and DC power distribution systems. Installed in sub-distribution boards, it provides reliable protection in (DC+)–PE and (DC–)–PE modes, safeguarding critical equipment from transient overvoltage.
With a nominal discharge current of 20kA (8/20μs) and high-energy MOV technology, it ensures stable, long-term performance in demanding solar environments. The pluggable D4 module design enables fast replacement and simplified maintenance.
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 industrial DC installations worldwide.
