DV1-C40/3(S) 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 effective protection in L-PE and N-PE modes, using high-energy MOV technology for fast response and reliable surge diversion.

With a nominal discharge current of In = 20 kA (8/20 μs), this SPD ensures stable protection for sensitive electrical and electronic equipment. The pluggable modular design allows quick replacement, minimizing downtime and maintenance effort.

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