Varistor module T2 40kA 1000 VDC 414186

Surge Protection for DC Circuits

This Class T2 varistor module is a key component for protecting photovoltaic installations and other DC circuits with voltages up to 1000 VDC. It provides effective protection against the effects of lightning discharges and voltage surges, minimizing the risk of damage to connected equipment. The module's design, intended for base mounting, facilitates installation and replacement when necessary.

Features and Applications

The varistor module is designed for surge protection in DC systems, offering a protection level of 4 kV. Its ability to absorb current impulse energy reaches up to 40 kA (maximum discharge current), while the nominal discharge current is 20 kA. This makes it ideal for protecting sensitive components in photovoltaic installations, battery charging systems, and other applications utilizing direct current. The single-channel design (1 wire) allows for precise adaptation to specific installation requirements.

Advantages and Benefits

• High protection effectiveness: Class T2 ensures a fast and efficient response to surges, protecting connected devices from damage.
• Designed for DC: Specifically engineered for operation with DC voltage up to 1000 VDC, making it an ideal choice for photovoltaic installations.
• Easy installation and replacement: Base mounting and mechanical module coding guarantee simple and safe installation and replacement when needed.
• Compact dimensions: Occupies only 1 module in the distribution board, allowing for optimal space utilization.
• Wide range of applications: Suitable for various network configurations (including non-standard TN, TT, or IT systems) thanks to the designation "Other network system: yes".
• Durability and reliability: Constructed from high-quality materials ensuring long-term, trouble-free operation. IP20 protection rating provides protection against accidental contact.
• Safety: The absence of tripping indication on the device means no unnecessary components complicate the installation – protection operates discreetly but effectively.

Thanks to these features, the Legrand 414186 varistor module represents a reliable solution for anyone concerned with the safety and durability of their DC electrical installation.
