Surge arrester T2 (C) - for PV systems ETITEC M T2 PV 1100/20 Y RC 002440516

Photovoltaic installation protection – surge arrester ETITEC M T2 PV

This class T2 (C) surge arrester is specifically designed for DC photovoltaic (PV) systems. Its function is to protect sensitive installation components from the effects of overvoltages that can occur due to lightning strikes or rapid voltage changes. Mounting on a TH-35 mm DIN rail ensures easy installation and integration with the existing protection system.

This arrester effectively protects against damage caused by sudden voltage surges, which translates to a longer lifespan and reliability of the entire PV installation. Thanks to this, both installers and end-users can be confident in the safety and efficiency of the system.

Construction and operating parameters

The device is characterized by a compact design – it occupies 3 modules on a DIN rail. The rated discharge current of 20 kA (8/20 μs) guarantees effective protection even in the event of strong overvoltages. Designed to operate in DC circuits with a rated voltage of 1100 V, and its maximum wire cross-section is 35 mm² for single- and multi-core wires and 25 mm² for flexible wires. It also has optical operating status indication, informing about the need for replacement after a surge.

It is worth paying attention to the DC network configuration – the device is designed to work in such configurations. Additionally, the presence of a remote signaling contact allows integration with monitoring systems and failure notifications. Made in varistor technology, it provides a fast and effective response to overvoltages.

Application and benefits

The ETITEC M T2 PV surge arrester is used in photovoltaic installations for both domestic and industrial needs. It is a key element of the overvoltage protection system, which minimizes the risk of damage to inverters, solar panels and other components. Therefore, investing in this arrester translates into savings related to repairs and replacement of damaged devices.
