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.

Frequently Asked Questions
What is the Finder 7P.00.1.000.0050 used for?
The Finder 7P.00.1.000.0050 is a replacement spark-gap module used in compatible Finder 7P Series surge protection devices. It provides a neutral-to-protective-earth discharge path for high-energy transient surge currents.
Is the Finder 7P.00.1.000.0050 a complete surge protection device?
No. This product is a replaceable spark-gap cartridge, not a complete standalone surge protection device. It must be installed in a compatible Finder SPD base or assembly specified for this module.
What is the lightning impulse current rating?
The module has a 50 kA lightning impulse current rating (Iimp), tested using the 10/350 µs waveform associated with high-energy lightning surge conditions.
What is the maximum continuous operating voltage?
The Finder 7P.00.1.000.0050 has a maximum continuous operating voltage (Uc) of 255 V AC. This is the specified continuous voltage capability of the spark-gap module, not a separate power supply requirement.
What is the difference between Iimp, In and Imax?
Iimp represents lightning impulse current capability using a 10/350 µs waveform, In represents nominal discharge current using an 8/20 µs waveform, and Imax represents maximum discharge current using an 8/20 µs waveform. For this module, the respective ratings are 50 kA, 50 kA and 100 kA.
What is the voltage protection level of this module?
The specified voltage protection level (Up) is 1.5 kV. Actual protection of connected equipment depends on the complete surge protection arrangement, installation wiring and coordination with other protective devices.
What is the difference between the Finder 7P.00.1.000.0050 and 7P.00.1.000.0100?
Both are Finder 7P Series spark-gap replacement modules with a 255 V AC maximum continuous operating voltage. The 7P.00.1.000.0050 has a 50 kA Iimp rating, while the 7P.00.1.000.0100 has a 100 kA Iimp rating. They should only be interchanged where the manufacturer confirms compatibility with the complete SPD assembly.
Can this module be mounted directly on a DIN rail?
No. The 7P.00.1.000.0050 is a plug-in replacement element intended for a compatible surge protection base. The complete SPD assembly may be DIN rail-mounted, but the cartridge is not designed for independent installation.
What operating temperature range does the module support?
The Finder 7P.00.1.000.0050 has an operating temperature range of −40 to +80 °C, supporting use in suitably protected electrical enclosures across a broad range of ambient conditions.
Does this spark-gap module require an external power supply?
No. The module is a passive surge protection component. Its 255 V AC rating refers to maximum continuous operating voltage, not to a power supply required for normal operation.
How should the Finder 7P.00.1.000.0050 be replaced?
Replacement should be performed by a suitably qualified electrical professional after the relevant installation has been safely isolated. The replacement cartridge must match the compatible Finder SPD assembly, and the manufacturer's installation and maintenance instructions must be followed.
