Why Choose the Finder 7P.12.8.275.1012 Surge Protection Device?
The Finder 7P.12.8.275.1012 is a compact and reliable Type 1+2 surge protection device (SPD) designed to protect single-phase low-voltage electrical installations against transient overvoltages caused by direct or indirect lightning discharges, induced surges and switching events. As part of the Finder 7P Series, it is suitable for 230/400 V AC systems requiring dependable protection at the boundary between lightning protection zones.
This surge arrester uses a coordinated varistor and gas discharge tube (GDT) protection arrangement to help limit damaging voltage peaks before they reach sensitive equipment. Its modular DIN rail design supports straightforward installation inside distribution boards, control panels and switchboards, while the replaceable protection elements help simplify servicing.
With a 275 V AC rating, 1+NPE pole configuration and 12.5 kA lightning impulse current, the Finder 7P.12.8.275.1012 is ideal for single-phase electrical systems where high-performance Type 1+2 surge protection is required for building services, automation panels and sensitive downstream equipment.
