Surge arrester for photovoltaics TYPE 1+2 SPPVRET12-10-2+PE EP-502585

Photovoltaic installation protection – reliability and safety

This surge protector class 1+2 is specifically designed to protect photovoltaic installations. It provides effective protection against the effects of lightning strikes and surges that can damage sensitive PV system components such as inverters and solar panels. Its quick and easy mounting on a TH-35 mm DIN rail will be appreciated by installers.

This surge protector stands out with its high parameters, which guarantee solid protection. A surge current of 5 kA and a rated discharge current of 20 kA (8/20 µs) effectively dissipate surge energy. A protection level of 4.4 kV provides a high degree of protection against damage. Optical indication of operation facilitates quick identification of a situation where the surge protector has reacted to a surge, allowing for efficient diagnostics and possible replacement.

Key features and application

• Protection class 1+2: Combination of protection against direct and indirect lightning strikes.
• DC 1000 V voltage: Suitable for operation with photovoltaic installations up to 1000 V DC.
• 3 modules: Compact size facilitates mounting in distribution boards.
• Wire cross-sections up to 35 mm²: Possibility of connecting wires of different thicknesses, adapted to the needs of the installation.
• Optical signaling: Visual information about the surge protector's operation – helpful in servicing and diagnostics.
• Specific energy 1.56 kJ/Ohm: High specific energy value indicates the ability to absorb large surges.

This surge protector is intended for use in photovoltaic installations with a DC network system, providing comprehensive protection against the effects of surges. The degree of protection IP20 indicates its intended use for indoor mounting, in dry and clean rooms. Thanks to this, the investor can sleep peacefully knowing that their installation is properly protected against potential failures caused by sudden voltage changes. The installer, in turn, will be confident in a solid product that will perform its task in critical situations.
