Protect your electrical equipment from unexpected voltage spikes with the NSP1-C40 AC Surge Protective Device (SPD). Designed for low-voltage AC distribution systems, this 2 Pole Type 2 SPD effectively diverts surge currents caused by lightning and electrical switching, preventing damage to sensitive electrical and electronic equipment.

With a 385V AC maximum continuous operating voltage (Uc), 20kA nominal discharge current (In), and 40kA maximum discharge current (Imax), the NSP1-C40 delivers dependable surge protection for distribution boards, control panels, industrial machinery, and household electrical systems.

Its compact DIN rail mounting design ensures quick installation, while the built-in status indicator allows easy monitoring. A green indicator confirms normal operation, and a red indicator signals that the protection module should be replaced.

Manufactured in compliance with IEC 61643-11, the NSP1-C40 provides long-lasting performance and reliable surge protection for modern electrical systems.
