Modular surge protector MOD. SM T12 PV 600/12,5 M 002440633

Protection of photovoltaic installations against overvoltage

The modular surge protector MOD. SM T12 PV 600/12.5 M is a key element protecting photovoltaic installations – both PV modules and other components – against the effects of overvoltage. The device protects against surges from lightning strikes (indirect and direct) and switching surges. Its use is particularly important in facilities equipped with photovoltaic systems, where the risk of damage caused by overvoltage is increased.

Construction and application

This surge protector is designed for mounting inside distribution boards and connection boxes. The modular design allows for flexible adaptation to the needs of a specific installation. Each pole has an internal thermal protection in the form of a disconnector, which increases safety and minimizes the risk of failure. This is an ideal solution for both installers and end users who value reliability and long-lasting protection of the photovoltaic system.

Advantages and benefits

• Effective protection: Protects the photovoltaic installation from damage caused by atmospheric and switching surges.
• Internal thermal protection: A disconnector in each pole provides additional safety and protects against overheating.
• Modular design: Enables easy installation and replacement if necessary.
• No leakage current (DC): Eliminates the risk of unwanted leakage currents, which affects the stability of the system.
• Fast response time: The response time to overvoltage is less than 100 ns, providing almost instantaneous protection.
• Compliance with standards: The device meets the requirements of EN/IEC standards, guaranteeing high quality and safety of use (VDE standard has been withdrawn).
• Versatility: Suitable for use in various types of photovoltaic installations.

The continuous operating voltage Uc (DC) is 1200 V, and the rated discharge current Iimp (10/350) is less than 4.4 kA. The leakage current IPE (DC)/(AC) is negligible or below 5 μs, and the response time tA is less than 100 ns. The tightening torque is 0.25 Nm, and the maximum conductor cross-section is 1.5 mm².

The MOD. SM T12 PV 600/12.5 M surge protector is an investment in the safety and longevity of the photovoltaic system – both for professional installers looking for reliable solutions and for end users who want to protect their investment for years to come.
