Why Choose the Finder 7P.20.8.130.0015 Replacement Surge Protection Cartridge?
The Finder 7P.20.8.130.0015 is a replaceable varistor surge protection cartridge designed for compatible Finder 7P Series surge protection devices (SPDs). This plug-in replacement module provides dependable protection against transient overvoltages caused by electrical switching operations and lightning-induced disturbances, helping maintain the performance of electrical surge protection systems.
Featuring a 130 V AC / 170 V DC maximum continuous operating voltage (Uc), a 15 kA nominal discharge current (In) and a 40 kA maximum discharge current (Imax), the Finder 7P.20.8.130.0015 is designed to absorb and divert high-energy transient surge currents. Its 0.6 kV voltage protection level (Up) helps limit the residual voltage reaching connected electrical equipment.
As a replacement protection module rather than a complete DIN rail surge arrester, the 7P.20.8.130.0015 fits into a compatible Finder SPD base. Its plug-in design simplifies maintenance by allowing a worn or damaged varistor cartridge to be replaced without replacing the complete surge protection assembly.

High-Performance Varistor Surge Protection Technology
The Finder 7P.20.8.130.0015 uses metal oxide varistor technology to protect compatible electrical circuits against transient overvoltages. During normal operation, the varistor presents high electrical resistance. When a sufficiently high transient voltage occurs, its resistance decreases rapidly, allowing surge current to be diverted through the surge protection assembly.
With a 15 kA nominal discharge current and a 40 kA maximum discharge current, the cartridge is designed to withstand substantial transient surge events. Its 0.6 kV voltage protection level at nominal discharge current helps reduce the voltage stress experienced by downstream equipment.
The 25 ns response time supports rapid protection against short-duration electrical transients. Actual equipment protection depends on the complete SPD assembly, installation wiring, earthing arrangement and coordination with other surge protection devices.
Convenient Replacement for Finder 7P Series Surge Arresters
Surge protection components can deteriorate over time as they absorb transient energy. The Finder 7P.20.8.130.0015 provides a convenient replacement option for compatible Finder surge arresters, allowing the protective varistor module to be renewed while retaining the existing SPD base.
This modular design helps reduce maintenance time and unnecessary component replacement. It is particularly useful in electrical distribution boards and industrial control cabinets where surge protection equipment is inspected as part of a planned maintenance programme.
Before ordering, verify that the installed SPD requires the 130 V AC / 170 V DC varistor cartridge and that its exact replacement code is 7P.20.8.130.0015. The module must not be substituted for a different voltage rating or installed as a standalone surge protection device.
