Surge protection module EM T2 PV 550/20 002440627

Photovoltaic installation protection – reliable surge arrester

The EM T2 PV 550/20 surge arrester exchangeable module is a key element protecting the photovoltaic installation from the effects of surges that may occur due to lightning strikes or rapid voltage changes in the grid. It provides protection for PV system components such as solar panels, inverters and cabling, minimizing the risk of failure and downtime. This is particularly important for installations exposed to frequent storms or in areas with an unstable power grid.

Design and application

The surge arrester from the GREEN PROTECT series by ETI POLAM is designed for mounting on a TH35 rail. Its compact size (1 module) allows for easy integration with an existing distribution board. It is an exchangeable module, which means that in the event of damage, it can be easily and quickly replaced with a new one, without the need to replace the entire housing. Designed for operation in DC systems with a maximum voltage of 550V, it effectively protects against surges with a peak value of up to 20kA (8/20µs). Optical signaling informs about the operation of the arrester, which facilitates diagnostics and rapid response in the event of a problem.

Advantages and benefits for the installer and user

• Quick installation: The modular design and mounting on a TH35 rail significantly speed up the installation process.
• Easy replacement: The exchangeable module allows for minimizing downtime in the event of a failure – just replace the module itself, not the entire device.
• High efficiency: The rated discharge current of 20kA provides effective protection against surges.
• Optical signaling: Facilitates diagnostics of the device status and quick identification of any problems.
• Investment protection: By protecting PV system components from damage caused by surges, it reduces repair and replacement costs.
• Compliance with standards: The product meets the relevant safety standards, ensuring reliable operation and safety of use.
• Compact dimensions: Occupies only 1 module in the distribution board, saving space.
