Why Choose the Finder 7P.13.9.000.1006 Type 1+2 Photovoltaic Surge Protection Device?
The Finder 7P.13.9.000.1006 is a high-performance Type 1+2 DC surge protection device (SPD) designed to protect photovoltaic installations against transient overvoltages caused by direct lightning strikes, induced lightning surges and electrical disturbances. As part of the Finder 7P Series surge protection range, this combined lightning current and surge arrester provides dependable protection for solar PV electrical systems operating at voltages up to 1050 V DC.
The device combines Type 1 lightning impulse protection and Type 2 surge protection within a compact DIN rail-mounted assembly. Its varistor-based protection technology helps divert damaging transient currents away from sensitive photovoltaic equipment, reducing the risk of electrical damage and unplanned system downtime. Integrated visual status indication and a remote signalling contact simplify condition monitoring and maintenance.
With a 1050 V DC maximum continuous operating voltage, 20 kA nominal discharge current and 12.5 kA lightning impulse current rating, the Finder 7P.13.9.000.1006 is suitable for solar PV installations requiring coordinated protection against lightning and switching surges. Its IP20 enclosure, compact construction and standard 35 mm DIN rail mounting enable straightforward integration into photovoltaic combiner boxes, DC distribution panels and electrical protection enclosures.

Reliable Surge Protection for Photovoltaic Power Systems
Photovoltaic installations are particularly vulnerable to transient overvoltages because solar arrays, DC cabling and associated electrical equipment may be exposed to lightning-induced electrical disturbances. Surge protection devices such as the Finder 7P.13.9.000.1006 help protect sensitive equipment by providing a controlled path for transient surge currents, limiting the voltage reaching connected components.
The Finder 7P Series combines lightning current protection and surge limitation within a single device, making it suitable for photovoltaic installations where both Type 1 and Type 2 protection are required. The integrated remote signalling contact allows the condition of the surge protection element to be monitored through compatible alarm or supervisory systems, supporting preventative maintenance and improved installation reliability.
Typical Applications
- Residential and commercial photovoltaic installations.
- Industrial solar power generation systems.
- Photovoltaic DC combiner boxes and distribution enclosures.
- Solar inverter DC input protection.
- Rooftop and ground-mounted solar PV arrays.
- Photovoltaic installations with external lightning protection systems.
- Solar energy systems requiring Type 1+2 surge protection.
- Renewable energy installations incorporating remote SPD condition monitoring.
