Surge arrester T2 for PV systems ETITEC EM T2 PV 1100/20 Y 002440623

Photovoltaic installation protection – surge arrester ETITEC EM T2 PV 1100/20 Y

This modular surge arrester is designed to protect photovoltaic installations from the effects of surges that can occur during storms or other network disturbances. The device effectively protects sensitive PV system components, such as inverters and solar panels, minimizing the risk of failures and downtime. Mounting on a TH-35 mm DIN rail makes integration with existing infrastructure simple and quick.

Characteristics and application

The ETITEC EM T2 PV 1100/20 Y surge arrester is designed to operate in DC systems with a voltage of up to 1100 V. Its T2 technology-based design ensures a fast and effective response to sudden voltage spikes. Optical indication of operation makes it easy to identify a situation where the arrester has reacted to a surge, allowing for quick diagnosis and possible replacement. The rated discharge current of 20 kA (8/20) guarantees effective protection against high current pulses.

Construction and mounting

The device occupies 3 modules on a TH-35 mm DIN rail, allowing for compact placement in a distribution box. It accepts conductor cross-sections up to 35 mm² (single-/multi-stranded) and 25 mm² (flexible), ensuring compatibility with various types of cabling used in photovoltaic installations. The IP20 degree of protection indicates protection against touching with fingers, which is important for the safety of installers and end-users. The arrester is intended for DC network systems, making it an ideal solution for photovoltaic installations connected directly to solar panels.
