Modular surge arrester ETITEC SM T12 PV 1200/12,5 Y 002440630

Photovoltaic installation protection – reliable surge arrester ETITEC SM T12 PV

This ETITEC SM T12 PV 1200/12.5 Y modular surge arrester is a key element in protecting photovoltaic installations from the effects of surges, both atmospheric and switching. Designed to work with systems up to 1200V DC, it effectively protects sensitive components such as PV modules and inverters. Its construction based on varistors and a spark gap in a Y configuration provides comprehensive protection.

Construction and application – for the installer and user

The arrester is designed for mounting on a DIN TH-35 mm mounting rail, which facilitates its integration with the existing electrical infrastructure. Use in facilities equipped with an external lightning protection system further increases the level of safety. Internal thermal protection in each pole provides additional protection against overheating and damage. This makes the device not only effective but also durable and reliable.

This arrester is used in photovoltaic installations exposed to surges, ensuring the continuity of the system and minimizing the risk of failure. For the end user, this means peace of mind and confidence that their investment is adequately protected. For the installer – a guarantee of proper system operation and compliance with safety standards.
