Finder 7P.13.8.275.1012 Type 1+2 surge protection device for three-phase TN-C systems with 3+0 protection, 275 V AC operating voltage, 12.5 kA lightning impulse current and DIN rail mounting.
£376.34
The Finder 7P.13.8.275.1012 is a robust Type 1+2 surge protection device (SPD) designed to protect three-phase TN-C low-voltage electrical systems against transient overvoltages caused by direct lightning strikes, induced surges and switching events. Part of the trusted Finder 7P Series, it is engineered to safeguard industrial and commercial electrical installations where reliable surge protection is essential.
This surge arrester features three integrated varistor and encapsulated spark gap protection modules, providing coordinated protection between L1, L2, L3 and the PEN conductor. Its replaceable modules, visual status indication and remote signalling contact simplify maintenance while helping maximise system uptime.
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.13.8.275.1012 is ideal for electrical distribution boards, industrial control panels, road lighting, infrastructure and machinery installations operating on three-phase TN-C networks.
Surge protection devices help divert transient overvoltages away from sensitive electrical equipment before damage can occur. This helps protect switchgear, industrial automation equipment, power supplies, drives and control systems while improving the reliability of electrical installations.
The Finder 7P.13.8.275.1012 is specifically designed for three-phase TN-C installations requiring coordinated Type 1+2 protection at the boundary between lightning protection zones. Its replaceable modules and remote signalling functions make it well suited to demanding industrial environments.
