Type 2 surge protection module (class C) for PV systems MOD. SM T2 PV 600/20 S 002440636

Photovoltaic installation protection – reliable surge arrester

The MOD. SM T2 PV 600/20 S surge arrester exchangeable module is a key element in protecting photovoltaic installations from the effects of lightning strikes and surges. Designed to work with DC systems, it effectively protects sensitive components such as inverters and solar panels, ensuring continuous operation and minimizing the risk of failure. This solution is dedicated to both professional installers and owners of PV systems who value safety and long-term performance.

Construction and application

This arrester belongs to class T2, which means it is designed to protect against the indirect effects of lightning strikes. Its modular construction allows for quick and easy replacement in case of operation, minimizing installation downtime. Mounting is done on a base, which facilitates integration with existing infrastructure. The device signals its operation optically, allowing for quick identification of the need for replacement. The purpose of the arrester is primarily to protect photovoltaic installations – both grid-connected and off-grid.

Key features and benefits

• Effective protection: Protects the installation against surges with a peak value of up to 20kA (In 8/20μs), and the maximum impulse discharge capacity is 40kA.
• DC 600V operating voltage: Suitable for most standard photovoltaic systems.
• MOV and GDT technology: The combination of these technologies provides a fast response to surges and high device durability.
• Modular construction: Allows easy replacement of the damaged module without the need to disassemble the entire housing.
• Optical signaling: A visual indicator informs about the need for replacement after the arrester has operated.
• Base mounting: Facilitates integration with existing electrical infrastructure.
• Protection class IP20: Provides basic protection against touch and dust – suitable for mounting inside buildings or in electrical enclosures.
• Compliance with standards: The product meets the requirements of IEC/VDE II/C standards, guaranteeing safety and reliable operation.
• Compact size (1 module): Allows you to save space in the switchgear cabinet.

The MOD. SM T2 PV 600/20 S arrester is an investment in the safety and longevity of your photovoltaic installation – both for professionals involved in installation and for users who value the reliable operation of the PV system for many years.
