Surge arrester T1 T2 (B and C) for PV systems ETITEC EM T12 PV 1100/6,25 Y 002440580

Photovoltaic installation protection – surge arrester ETITEC EM T12 PV 1100/6,25 Y

This three-pole surge arrester from the ETITEC EM T12 PV series is designed to protect photovoltaic installations from the effects of lightning strikes and surges. Protection class Type 1+2 (B+C) provides comprehensive protection against both direct and indirect lightning strikes. The device effectively limits the voltage to a safe level of 3.8 kV, protecting connected devices and extending their lifespan.

This surge arrester is widely used in photovoltaic installations in residential and commercial buildings, ensuring safety for both users and the installation itself. Mounting on a TH-35 mm DIN rail makes it easy to integrate with existing electrical infrastructure.

Characteristics and installation

The design based on varistor technology guarantees a quick response to surges and effective energy dissipation. The maximum wire cross-section of up to 35 mm² (solid/stranded) and 25 mm² (flexible) allows connection of a wide range of wires. The three modules occupied by the arrester provide compact dimensions, and mounting on a TH-35 mm DIN rail is simple and intuitive – this will be particularly appreciated by installers. The surge current level of 6.25 kA demonstrates the high effectiveness of the device in the event of strong surges.

It is worth noting the high rated current of 275 A and the follow current extinguishing capability at the level of 40 kA – these are parameters important for ensuring reliable protection in demanding operating conditions. The arrester is designed for DC network systems, making it an ideal solution for photovoltaic installations.
