DV1-C40/1(S)+1 Pluggable Single-pole Surge Protection Device (SPD) is designed to protect low-voltage AC circuits installed in sub-distribution boards from transient overvoltages caused by lightning strikes and switching operations. It provides effective surge protection in L-N and N-PE modes, ensuring reliable safeguarding of sensitive electrical and electronic equipment.

With a nominal discharge current of In = 20 kA (8/20 μs), this SPD delivers stable and consistent surge suppression using high-energy MOV technology. The pluggable modular design allows fast replacement and simplified maintenance without rewiring, reducing downtime.

Compliant with IEC/EN 61643-11 and classified as Class II / Type 2, the DV1-C40/1(S)+1 is ideal for commercial buildings, industrial panels, infrastructure systems, and telecom installations requiring compact, serviceable surge protection.
