Why Choose the Finder 7P.00.1.000.0050 Spark-Gap Replacement Module?
The Finder 7P.00.1.000.0050 is a high-performance 50 kA spark-gap replacement module designed for use with compatible Finder 7P Series surge protection devices (SPDs). Engineered for the neutral-to-protective-earth (N-PE) protection path, this plug-in discharge module provides a practical replacement solution for maintaining surge protection in industrial, commercial and building electrical distribution systems.
Featuring a maximum continuous operating voltage (Uc) of 255 V AC and a 50 kA lightning impulse current rating (Iimp, 10/350 µs), the Finder 7P.00.1.000.0050 is designed to handle high-energy transient surge events. Its spark-gap technology provides a controlled discharge path for surge currents, helping protect electrical installations against the effects of lightning-related overvoltages.
The module also provides a 100 kA maximum discharge current (Imax, 8/20 µs), a 1.5 kV voltage protection level (Up) and an operating temperature range of −40 to +80 °C. Designed for insertion into the appropriate Finder SPD base, it enables replacement of the protective element without replacing the complete compatible surge protection assembly.

Reliable Spark-Gap Protection for Electrical Distribution Systems
Electrical distribution systems can experience transient overvoltages caused by lightning activity and switching events. These surges can place significant stress on insulation, power supplies, control equipment and other connected electrical devices. The Finder 7P.00.1.000.0050 is designed to form part of a coordinated surge protection arrangement, providing a high-energy discharge path between neutral and protective earth when installed in its compatible SPD assembly.
Its spark-gap protection technology is particularly suited to the handling of high-energy impulse currents. With a specified 50 kA Iimp rating using a 10/350 µs waveform, the module is intended for applications requiring substantial lightning surge current capability. The 1.5 kV voltage protection level describes the module's surge-limiting performance under the relevant test conditions; the overall protection achieved in an installation also depends on the complete SPD assembly, wiring and earthing arrangement.
The replaceable cartridge design makes the module useful for planned maintenance and restoration of compatible Finder 7P Series protection devices. By replacing the correct protective element, maintenance engineers can retain the existing compatible SPD base rather than automatically replacing the complete assembly. Selection should always be based on the manufacturer's specified module compatibility and the installation's surge protection requirements.
