Surge arrester T1, T2 (B, C) - for PV systems ETITEC M T12 PV 1100/10 5Y 002440675

Photovoltaic installation protection – reliable surge arrester ETITEC M T12 PV

This surge arrester of class T1 and T2, dedicated to photovoltaic systems, is a key element ensuring the safety and long-term operation of your installation. Designed by ETI Polam, it protects against the effects of lightning strikes and surges that can damage sensitive PV system components. Mounting on a TH-35 mm DIN rail simplifies integration with existing infrastructure.

Design and parameters for professionals

The ETITEC M T12 PV 1100/10 surge arrester is characterized by high efficiency thanks to its 10 kA impulse current. The protection level of 3.8 kV guarantees effective protection against surges in both the DC + - DC- and DC + / DC - - PE circuits. The specific energy of 6.25 kJ/Ohm allows for the absorption of large surge energies, minimizing the risk of failure. The use of a DC network circuit confirms its intended use for photovoltaic systems. The maximum wire cross-section of 35 mm² (solid/stranded) and 25 mm² (flexible) ensures compatibility with most wiring used in PV installations. Optical signaling of operation facilitates quick identification of potential problems and allows for efficient system diagnostics.

Safety and reliability for the end user

This surge arrester is an investment in peace of mind. It protects your photovoltaic installation from sudden voltage spikes caused by storms or other disturbances in the power grid. Thanks to this, you can be sure that your solar panels and inverter will operate trouble-free for years to come, generating clean energy and saving you money. The compact design (5 modules) allows for discreet mounting inside the distribution box, and the IP20 degree of protection ensures safe operation in standard environmental conditions. The high DC continuous operating voltage (1100 V) makes it ideal for modern high-voltage photovoltaic systems.
