DV1-C40/3(S)+1 Pluggable Multi-pole Surge Protection Device (SPD) is designed to protect low-voltage AC systems installed in sub-distribution boards against transient overvoltages caused by lightning and switching operations. It provides coordinated protection in L-N and N-PE modes, ensuring reliable suppression of surges across multi-phase networks.

With a nominal discharge current of In = 20 kA (8/20 μs), this SPD uses high-energy MOV technology to deliver fast response and consistent protection for sensitive electrical and electronic equipment. The pluggable modular design enables quick replacement and easy maintenance without disturbing wiring.

Compliant with IEC/EN 61643-11 and classified as Class II / Type 2, the DV1-C40/3(S)+1 is ideal for industrial facilities, commercial buildings, data centers, and infrastructure distribution systems requiring dependable, serviceable surge protection.
