£274.49
The Finder 7P.09.1.255.0100 is a high-capacity Type 1 surge protection module designed specifically for neutral to protective earth (N-PE) protection in three-phase 3+1 surge protection configurations. Part of the trusted Finder 7P Series, it provides dependable protection against high-energy lightning currents and transient overvoltages in industrial and commercial electrical installations.
Designed for use alongside Finder 7P.01 Type 1+2 surge protection devices, this replaceable gas discharge tube (GDT) module delivers effective N-PE protection while maintaining high insulation resistance and eliminating leakage current during normal operation. Its modular design allows quick replacement, reducing maintenance time and improving system availability.
With a 255 V AC maximum continuous operating voltage, 100 kA lightning impulse current and compact 35 mm DIN rail mounting, the Finder 7P.09.1.255.0100 is ideal for low-voltage switchboards, industrial control panels and power distribution systems requiring professional-grade surge protection.
Neutral to protective earth surge protection is essential for protecting electrical installations against high-energy lightning currents. The Finder 7P.09.1.255.0100 is specifically engineered to provide dedicated N-PE protection within coordinated 3+1 surge protection systems, helping minimise the risk of damage to switchgear, automation equipment and sensitive electronics.
Its high discharge capability, replaceable construction and remote signalling functionality make it suitable for industrial switchboards, commercial buildings and critical infrastructure requiring dependable overvoltage protection.
