Why Choose the Finder 7P.13.8.275.1012 Surge Protection Device?
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.
