Why Choose the Finder 7P.03.8.260.1025 Surge Protection Device?

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.

Key Advantages

  • Type 1+2 surge protection device for three-phase TN-C systems.
  • 3-pole configuration for systems without separate neutral conductor.
  • Varistor + GDT protection for high discharge capability.
  • 25 kA lightning impulse current for high-energy surge events.
  • 30 kA nominal discharge current for dependable surge handling.
  • Visual and remote signalling supports easier maintenance monitoring.

Key Features

  • Finder 7P Series surge protection device.
  • Type 1+2 SPD classification.
  • Three-phase TN-C system compatibility.
  • 3-pole protection arrangement.
  • 260 V AC maximum continuous operating voltage.
  • Replaceable protection modules for efficient servicing.
  • 35 mm DIN rail mounting for electrical panels.
  • IP20 protection rating for enclosed installations.

Reliable Surge Protection for Three-Phase TN-C Systems

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.

Typical Applications

  • Three-phase TN-C electrical distribution boards.
  • Industrial control panels and automation cabinets.
  • Commercial switchboards and building services systems.
  • Machinery control systems and OEM electrical panels.
  • Facility power distribution and infrastructure installations.
  • Protection of sensitive electrical and electronic equipment.
