Surge protection module T1,T2 (class B,C) for PV systems MOD. ESM T12 PV 600/6,25 M 002440643

Photovoltaic installation protection – reliability and safety

The replaceable surge limiter module from the GREEN PROTECT series is a key element in protecting photovoltaic installations from the effects of lightning strikes and overvoltages. Designed to work with PV systems, it provides protection against both impulse and permanent voltage increases. Class T1+T2 (B+C) means that the module combines the features of a first and second degree protection limiter, guaranteeing comprehensive protection.

Construction and application

This limiter is a replaceable module, which means that in the event of its damage (e.g. after a strong lightning strike), it can be easily and quickly replaced without the need to disassemble the entire housing. This translates into minimal downtime of the installation and reduced service costs. Designed for mounting on a TH35 rail, it occupies only 1 module in the switchgear. Application in photovoltaic installations protects sensitive components – inverters, solar panels and other system elements – from damage caused by sudden voltage surges.

Key features and benefits

• Versatile protection: The combination of class T1 and T2 provides effective protection against various types of overvoltages.
• Easy replacement: The modular design allows for quick replacement of a damaged element without the need to interfere with the entire installation. This is particularly important for installers who value work efficiency.
• Optical signaling: A built-in optical indicator informs about the operation of the limiter, which facilitates diagnostics and allows for a quick response in the event of an overvoltage.
• Impulse current 6.25 kA (10/350 µs): The high impulse current value guarantees effective protection even during strong lightning strikes.
• Maximum DC voltage 600V: Dedicated to photovoltaic installations with a voltage of up to 600V DC.
• GREEN PROTECT series: A high-quality product from the renowned manufacturer ETI POLAM, characterized by reliability and durability.
• Mounting on TH35 rail: Standard mounting facilitates integration with existing switchgear.

This limiter is an investment in the long-term and safe operation of your photovoltaic installation – for both professional installers and end users. It provides peace of mind and minimizes the risk of costly failures.
