Photovoltaic system protection – surge arrester ETITEC ESM T2 PV 1200/20 Y

This modular surge arrester, designed for photovoltaic installations, provides effective protection against the effects of lightning strikes and overvoltages in the grid. The Class T2 device, with a rated DC voltage of 1200V, protects sensitive PV system components such as inverters and solar panels from damage caused by sudden voltage increases. Its installation is a key element in ensuring the reliability and longevity of the entire installation.

Characteristics and application

The ETITEC ESM T2 PV 1200/20 Y surge arrester is designed to work with photovoltaic installations with a DC voltage of up to 1200V. Fast response to overvoltages, thanks to the rated peak discharge current of 20 kA (8/20 µs) and the maximum discharge current of 40 kA (8/20 µs), minimizes the risk of failures and downtime in the system. Mounted in a DC distribution box on the side of the solar panels or inverter, it is an integral part of comprehensive overvoltage protection.

• Protection against damage: Protects photovoltaic installation components from overvoltages caused by lightning strikes or disturbances in the power grid.
• Increased reliability: Ensures stable operation of the PV system, minimizing the risk of failures and downtime.
• Long lifespan: High quality workmanship guarantees long-lasting and trouble-free operation of the device.
• Easy installation: Modular design simplifies installation in standard distribution boxes.
• Safety: Protects against potential hazards related to overvoltages, protecting both equipment and people using solar energy.

Construction and installation – for professionals

The ETITEC ESM T2 PV 1200/20 Y surge arrester is designed for mounting on a TH35 rail in a DC distribution box. Correct installation is crucial to ensure effective protection. It is important to maintain an appropriate distance between individual overvoltage protection elements and to properly connect grounding wires. Installation should be performed by a qualified electrician in accordance with applicable standards and regulations. It is worth paying attention to the correctly selected wire cross-sections and solid electrical connections, which affect the efficiency of the entire overvoltage protection system.
