£503.03
The Finder 7P.15.8.275.1012 is a high-performance Type 1+2 surge protection device (SPD) designed to protect three-phase TT and TN-S electrical installations with neutral against transient overvoltages caused by direct lightning strikes, induced surges and switching events. As part of the proven Finder 7P Series, it delivers dependable surge protection for industrial, commercial and infrastructure applications.
This surge arrester features a 3+N configuration with four high-performance varistor protection modules, providing coordinated protection for all phases and neutral. Its replaceable modules, compact DIN rail design and visual plus remote status indication simplify installation and maintenance while maximising system availability.
With a 275 V AC maximum continuous operating voltage, 12.5 kA lightning impulse current per pole and 30 kA nominal discharge current, the Finder 7P.15.8.275.1012 is ideally suited for protecting switchboards, automation panels, machinery and sensitive electronic equipment within modern three-phase power distribution systems.
Surge protection devices reduce the risk of damage caused by transient overvoltages by safely diverting surge energy away from connected equipment. This helps protect industrial drives, PLCs, switchgear, power supplies and automation systems while improving the reliability of electrical installations.
The Finder 7P.15.8.275.1012 is engineered for three-phase TT and TN-S systems where coordinated Type 1+2 protection is required at the boundary between lightning protection zones. Its replaceable modules and remote monitoring capability make it suitable for demanding industrial and commercial environments.
