Finder 7P.23.8.275.1020 Type 2 surge protection device for three-phase 230/400 V systems, featuring 3-pole varistor protection, 275 V AC maximum continuous operating voltage, 20 kA nominal discharge current and DIN rail mounting.
£155.97
The Finder 7P.23.8.275.1020 is a reliable Type 2 surge protection device (SPD) designed to protect three-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 230/400 V systems requiring dependable surge protection in distribution boards, switchboards and industrial control panels.
This surge arrester uses three replaceable varistor protection modules to provide coordinated protection across three-phase electrical systems. Its modular DIN rail design supports quick installation, while visual and remote signalling functions help indicate varistor status for easier maintenance and preventative inspection.
With a 275 V AC maximum continuous operating voltage, 20 kA nominal discharge current and IP20 protection rating, the Finder 7P.23.8.275.1020 is ideal for protecting switchgear, automation equipment, power supplies and sensitive electrical devices from damaging voltage peaks.
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 switchgear, power supplies, PLCs, drives, instrumentation and other sensitive electrical components.
The Finder 7P.23.8.275.1020 is designed for three-phase installations where compact, modular and maintainable surge protection is required. Its replaceable varistor modules and signalling functions make it suitable for professional industrial, commercial and OEM electrical panels.
