DV1-C40M/4(S) Pluggable Multi-pole Surge Protection Device (SPD) is designed to protect low-voltage AC systems installed in sub-distribution boards from transient overvoltages caused by lightning and switching events. It delivers coordinated protection in L-PE and N-PE modes, using high-energy MOV technology for rapid response and reliable surge dissipation.

With a nominal discharge current of In = 20 kA (8/20 μs), this multi-pole SPD provides robust protection for three-phase networks and sensitive downstream equipment. The pluggable modular design enables quick replacement and simplified maintenance without disturbing wiring, minimizing downtime.

Compliant with IEC/EN 61643-11 and classified as Class 1+2 / Type 1+2, the DV1-C40M/4(S) is ideal for industrial plants, commercial buildings, data centers, and critical infrastructure requiring dependable, serviceable surge protection.
