Surge arrester 1000Vdc type V-PV-T1+2-1000FS 5094232

Photovoltaic installation protection – reliability and safety

The V-PV-T1+2-1000FS surge protector is a key element in protecting photovoltaic installations from the effects of lightning strikes and overvoltages. The device combines the functions of Type 1 and 2 surge protectors, providing comprehensive protection against both direct and indirect lightning strikes. Using this type of protection is essential to ensure the continuous operation of the PV system and protect connected devices.

Design and application

The surge protector is designed for mounting on a TH-35 mm DIN rail, making it easy to integrate with existing electrical infrastructure. Specifically designed for photovoltaic installations with voltages up to 1000V DC, it effectively protects against damage caused by sudden voltage increases. The optical indication of the device's status allows for quick identification of any failures and the need for replacement.

Key features and benefits

• Versatile protection: The combination of a Type 1+2 surge protector provides protection against both direct lightning strikes and overvoltages from the grid.
• High efficiency: The impulse current level of 6.25 kA (10/350 µs) guarantees effective energy dissipation during lightning strikes. Additionally, the device withstands an impulse current of 40 kA (8/20 µs).
• Status indication: Optical indication of operation facilitates diagnostics and quick response in the event of a failure.
• Safety: Compliance with EN 50539-11 and IEC 60364-7-712 standards ensures a high level of safety for the installation and devices.
• Signaling contact: The FS variant is equipped with a potential-free changeover contact enabling remote signaling of the surge protector's operation – an ideal solution for monitoring systems.
• Solid construction: The housing with an IP20 degree of protection provides protection against touch and internal environmental influences.
• Large wire cross-section: The maximum wire cross-section of 35 mm² allows connection of wires with a large diameter, often found in photovoltaic installations.
• Y-configuration: Error-resistant Y-configuration increases the reliability of the device.

Installation and compliance with standards
