Why Choose the Finder 7P.05.8.260.1025 Surge Protection Device?
The Finder 7P.05.8.260.1025 is a high-performance Type 1+2 surge protection device (SPD) designed to protect three-phase low-voltage electrical installations from transient overvoltages caused by direct lightning discharge, induced surges and switching events. As part of the Finder 7P Series, it provides dependable protection for industrial, commercial and building services distribution systems.
This surge arrester is designed for three-phase 3+N systems and uses a 4+0 protection arrangement, with each phase and neutral protected to earth. Its modular DIN rail construction, replaceable protection modules and status signalling functions make it suitable for professional electrical panels where reliable surge protection and straightforward maintenance are essential.
With a 260 V AC maximum operating voltage, 25 kA lightning impulse current and IP20 protection rating, the Finder 7P.05.8.260.1025 is ideal for protecting electrical switchboards, automation panels, machinery control systems and sensitive downstream equipment from damaging voltage peaks.

Reliable Surge Protection for Three-Phase Electrical Panels
Surge protection devices help protect electrical installations by limiting transient overvoltages before they reach connected equipment. This reduces the risk of damage to power supplies, control devices, automation components, switchgear and sensitive electronic systems.
The Finder 7P.05.8.260.1025 is suitable for use in three-phase distribution systems where Type 1+2 protection is required at the boundary between lightning protection zones. Its combination of high discharge capability, DIN rail mounting and replaceable modules makes it a practical choice for industrial and commercial electrical installations.
Typical Applications
- Three-phase electrical distribution boards.
- Industrial control panels and automation cabinets.
- Commercial building services installations.
- Machinery control systems and OEM panels.
- Facility power distribution and switchboards.
- Protection of sensitive electrical and electronic equipment.
