Surge arrester T1, T2 (B, C) - for PV systems ETITEC M T12 PV 1500/10 Y RC 002440514

Photovoltaic installation protection – reliable surge arrester ETITEC

This three-pole ETITEC M T12 PV 1500/10 Y RC surge arrester is a key element in protecting photovoltaic installations from the effects of lightning strikes and overvoltages in the grid. Designed to work with DC systems, it protects against damage to inverters, panels and other sensitive components. Protection class Type 1+2 (B+C) provides comprehensive protection, reacting to both direct lightning strikes and disturbances from the grid.

Construction and installation – simplicity for professionals and users

The arrester is designed for mounting on a standard DIN TH-35 mm mounting rail, which facilitates its integration with existing infrastructure. The compact design (3 modules) allows for saving space in the switchgear cabinet. It accepts wire cross-sections up to 35 mm², ensuring compatibility with most cabling used in photovoltaic installations. Additionally, the maximum cross-section of flexible wire is 25 mm². An optical indicator signals the state of the varistor – green indicates correct operation, red – the need for replacement.

Key features and benefits

• Versatile protection: The combination of Type 1 and Type 2 (B+C) class guarantees effective protection against various types of overvoltages.
• High efficiency: Impact current of 12.5 kA effectively dissipates surge energy, minimizing the risk of damage.
• Safety: Rated DC voltage of 1500 V and protection level of 3.8 kV ensure safe operation of the installation in difficult conditions.
• Status indication: Built-in optical indicator informs about the need to replace the module after a surge.
• Easy installation: Standard mounting on DIN TH-35 mm rail simplifies installation and servicing.
• Signaling contact: The presence of a signaling contact enables integration with the installation monitoring system and quick response to failures.
• Compliance with standards: The product meets the requirements of IEC 61643-31:2018+A1:2014 standard, which confirms its quality and safety.

This arrester is not only a protective element, but also an investment in the long-term and trouble-free operation of the entire photovoltaic installation – both for professional installers and end users. It provides peace of mind and minimizes the risk of costly repairs resulting from damage caused by overvoltages.
