£941.46
The Finder 7P.04.8.260.1025 is a robust Type 1+2 surge protection device (SPD) designed to protect three-phase low-voltage electrical installations against transient overvoltages caused by lightning impulses, induced surges and switching events. As part of the Finder 7P Series, it is suitable for TT and TN-S three-phase systems with neutral.
This surge arrester uses varistor and gas discharge tube (GDT) protection between L1, L2, L3 and neutral, with additional spark gap protection between neutral and protective earth. This coordinated protection arrangement helps safeguard distribution boards, electrical switchboards and sensitive downstream equipment from damaging voltage peaks.
With a 230/400 V AC system suitability, 25 kA lightning impulse current and 30 kA nominal discharge current, the Finder 7P.04.8.260.1025 is ideal for industrial and commercial installations requiring dependable surge protection in three-phase systems with neutral.
Surge protection devices help protect electrical installations by limiting transient overvoltages before they reach sensitive equipment. This helps reduce the risk of damage to switchgear, control components, power supplies, automation hardware and connected machinery.
The Finder 7P.04.8.260.1025 is designed for installation in three-phase distribution boards and control panels where coordinated Type 1+2 surge protection is required. Its modular DIN rail format, replaceable modules and signalling functions make it a practical solution for professional industrial and commercial electrical systems.
