DV1-C40M/2(S) Pluggable Single-pole Surge Protection Device (SPD) is designed to safeguard low-voltage AC circuits in sub-distribution boards against transient overvoltages caused by lightning strikes and switching surges. It provides reliable protection in L-PE and N-PE modes, using high-energy MOV technology for rapid surge response and effective energy dissipation.

With a nominal discharge current of In = 10 kA (8/20 μs), this single-pole SPD is ideal for selective or point-of-use surge protection. The pluggable modular housing enables quick replacement and reduced maintenance time without disturbing system wiring.

Compliant with IEC/EN 61643-11 and classified as Class 1+2 / Type 1+2, the DV1-C40M/2(S) is well suited for industrial panels, commercial buildings, telecom systems, and infrastructure power networks requiring compact, serviceable surge protection.
