Finder 7P.00.8.260.0025 – 7P Series Surge Protection Devices

Why Choose the Finder 7P.00.8.260.0025 Surge Protection Replacement Module?

The Finder 7P.00.8.260.0025 is a high-performance Type 1+2 surge protection replacement cartridge from the Finder 7P Series, designed to restore surge protection capability in compatible electrical surge protection devices (SPDs). Combining a metal oxide varistor and encapsulated gas discharge tube (GDT), this replaceable module provides protection against transient overvoltages associated with lightning activity and electrical switching events.

Featuring a 25 kA lightning impulse current rating (10/350 µs), 30 kA nominal discharge current (8/20 µs) and 60 kA maximum discharge current (8/20 µs), the Finder 7P.00.8.260.0025 is designed for demanding low-voltage electrical installations. Its 260 V AC maximum continuous operating voltage (Uc) and 1.5 kV voltage protection level (Up) support effective transient overvoltage limitation when fitted into an appropriate Finder 7P surge protection assembly.

As a plug-in replacement module, the 7P.00.8.260.0025 allows maintenance engineers and electrical contractors to replace the protective cartridge without replacing the complete compatible SPD assembly. This helps simplify planned maintenance, reduce unnecessary component replacement and maintain surge protection in industrial control panels, electrical distribution boards and building electrical installations.

Reliable Surge Protection Maintenance for Industrial Automation and Electrical Distribution

Industrial electrical installations can be exposed to transient overvoltages caused by lightning activity, electrical switching operations and disturbances within the supply network. These events can damage sensitive equipment, including PLCs, variable speed drives, communication interfaces, power supplies and electronic control systems.

The Finder 7P.00.8.260.0025 provides a replaceable protective element for compatible Finder Type 1+2 surge protection devices. Its combined varistor and encapsulated gas discharge tube technology is designed to handle high-energy impulse currents while limiting the voltage appearing across protected circuits.

The module's 25 kA lightning impulse current rating is specified using the 10/350 µs waveform associated with Type 1 surge protection testing. Its 30 kA nominal discharge current and 60 kA maximum discharge current are specified using the 8/20 µs waveform, supporting protection against transient overvoltage events.

With a 260 V AC maximum continuous operating voltage and 1.5 kV voltage protection level, the module is intended to operate as part of a correctly selected and installed surge protection assembly. The overall protection achieved depends on the complete SPD configuration, electrical earthing arrangement, conductor routing and coordination with other protective devices.

Its plug-in replacement design is particularly valuable for maintenance engineers. Where the compatible SPD indicates that its protective cartridge requires replacement, the module can be exchanged in accordance with Finder's instructions without replacing the entire SPD base. Electrical isolation and appropriate safety procedures are essential before carrying out replacement work.

The Finder 7P.00.8.260.0025 is a replacement cartridge rather than a complete standalone DIN rail-mounted surge arrester. It must be fitted into a compatible Finder 7P assembly. Engineers should verify the exact host SPD model and required protective element before installation.
