DV1-C40M/1(S)+1 Pluggable Single-pole Surge Protection Device (SPD) is engineered to protect low-voltage AC circuits in sub-distribution boards from lightning-induced and switching surges. Designed for L-N and N-PE protection modes, it provides coordinated surge suppression for sensitive downstream equipment.

With a nominal discharge current of In = 20 kA (8/20 μs), this SPD combines high-energy MOV and GDT (GOT) technology to deliver fast response, high surge endurance, and reliable long-term protection. The pluggable modular design enables quick replacement and easy maintenance without rewiring, reducing downtime.

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