Finder 7P.03.8.260.1025 Type 1+2 surge protection device for three-phase TN-C systems, featuring varistor and GDT protection, 260 V AC maximum continuous operating voltage, 25 kA lightning impulse current and DIN rail mounting.
£665.75
The Finder 7P.03.8.260.1025 is a robust Type 1+2 surge protection device (SPD) designed to protect three-phase TN-C low-voltage electrical systems from transient overvoltages caused by direct lightning discharges, induced surges and switching events. As part of the Finder 7P Series, it provides dependable surge protection for industrial, commercial and infrastructure electrical installations.
This surge arrester uses a combination of high-performance varistors and gas discharge tube (GDT) protection across L1, L2 and L3 to PEN. Its replaceable modules, visual status indication and remote signalling contact help simplify maintenance while supporting reliable operation in demanding electrical distribution systems.
With a 260 V AC maximum continuous operating voltage, 25 kA lightning impulse current and 30 kA nominal discharge current, the Finder 7P.03.8.260.1025 is ideal for three-phase switchboards, control panels and power distribution systems requiring coordinated Type 1+2 surge protection.
Surge protection devices help protect electrical installations by limiting transient overvoltages before they reach connected equipment. This helps reduce the risk of damage to switchgear, power supplies, control devices, automation components and sensitive electronic systems.
The Finder 7P.03.8.260.1025 is designed for installation at the boundary between lightning protection zones where Type 1+2 protection is required. Its modular construction, replaceable modules and signalling functions make it a practical choice for industrial and commercial three-phase TN-C installations.
