The Finder 7P.22.8.275.1020 is a compact and reliable Type 2 surge protection device (SPD) designed to protect single-phase low-voltage electrical installations from transient overvoltages caused by induced surges and switching events. As part of the Finder 7P Series, it is suitable for TT and TN-S systems requiring dependable surge protection inside distribution boards, control panels and switchboards.
This surge arrester combines a replaceable varistor module with an encapsulated spark gap module, providing coordinated protection between line, neutral and protective earth. Its visual and remote signalling functions help identify device status, making inspection and preventative maintenance easier for electrical contractors and panel builders.
With a 230 V AC nominal voltage, 275 V AC maximum continuous operating voltage, 20 kA nominal discharge current and compact DIN rail mounting, the Finder 7P.22.8.275.1020 is ideal for protecting sensitive equipment in commercial, industrial and building services installations.
Type 2 surge protection devices are commonly installed in electrical distribution boards and control panels to limit transient overvoltages before they reach connected equipment. This helps protect power supplies, PLCs, control devices, switchgear, instrumentation and sensitive electronic systems.
The Finder 7P.22.8.275.1020 is designed for use at the boundary between LPZ 1 and LPZ 2, providing effective protection against induced and switching overvoltages. Its compact modular design, DIN rail mounting and status signalling make it a practical choice for professional electrical installations.
