Replacement module for Type 2 surge arrester (class C) for PV module systems M T2 PV 750/20 002440524

Photovoltaic installation protection – replaceable module for surge limiter

This replaceable module is designed for Type 2 surge limiters dedicated to photovoltaic systems. It provides effective protection against the effects of surges that can occur in PV installations, protecting connected devices and extending their lifespan. It is a key element ensuring the safety and reliability of the entire system.

Characteristics and application

The M T2 PV 750/20 module is designed to work with surge limiters in DC systems with a voltage of up to 750V. It utilizes varistor technology, which effectively suppresses surges by dissipating excess energy to ground. Its construction allows for easy replacement in the event of a limiter activation, minimizing installation downtime. Thanks to this, after a surge occurs, it is not necessary to replace the entire limiter, but only the damaged module – this saves time and money.

Key features and benefits

• Overvoltage protection: Protects the photovoltaic installation from the effects of lightning strikes and other network disturbances.
• Varistor technology: Provides a fast and effective response to surges.
• Modular design: Enables quick and easy replacement of the damaged element without the need to disassemble the entire limiter. This is particularly important for installers who can quickly restore system operation for the client.
• Impulse current 20kA: Withstands a current flow of 20kA (8/20μs), providing a high level of protection. The maximum discharge current is 30kA (8/20μs).
• DC voltage 750V: Suitable for operation in photovoltaic systems with a DC voltage of up to 750V.
• Optical signaling: An optical indicator informs about the operation of the limiter, facilitating diagnostics and maintenance of the installation.
• Base mounting: Standard base mounting allows for easy integration with existing surge limiters. It occupies one module in the switchgear.
• Protection degree IP20: Provides basic protection against accidental contact and contamination.
