Surge arrester module T1,T2 (class B,C) for PV systems MOD. M T12 PV 550/5 10Y M 002440677

Photovoltaic installation protection – surge arrester exchangeable module

This exchangeable surge arrester module, class T1 and T2 (B and C), is designed to protect photovoltaic (PV) systems from the effects of overvoltages. It is a key element of protection for both installers and end-users, ensuring reliable operation and longevity of the system. This module is part of the GREEN PROTECT series from ETI POLAM.

Characteristics and application

The surge arrester protects sensitive components of the PV installation, such as inverters and solar panels, against sudden voltage increases caused by lightning strikes or other network disturbances. Class B and C means that the device provides protection against both direct and indirect overvoltages. The impulse current of 10 kA guarantees an effective response to strong current pulses. The DC voltage of 550V makes it compatible with most standard photovoltaic installations.

The exchangeable module is a practical solution – in the event of damage to the arrester during a surge, it can be easily replaced without having to disassemble the entire housing. This saves time and costs for both service and the user.

Advantages and benefits

• Effective protection: Protects the PV installation from damage caused by overvoltages, minimizing the risk of downtime and costly repairs.
• Module replaceability: Enables quick and easy replacement of a damaged element without having to replace the entire device – this saves time and money.
• Class T1+T2: Provides comprehensive protection against various types of overvoltages, both direct (lightning strikes) and indirect (network disturbances).
• Adapted to PV systems: Specifically designed to operate in photovoltaic installations with a DC voltage of 550V.
• High impulse resistance: Impulse current of 10 kA guarantees effective protection even with strong overvoltages.
• GREEN PROTECT series: Product comes from the ETI POLAM line dedicated to ecological and energy-saving solutions.

Let's remember that proper selection of a surge arrester and its installation in accordance with applicable standards is the basis for safe and reliable operation of the photovoltaic installation.
