Modular surge protector MOD. ESM T2 PV 600/20 S 002440682

Photovoltaic installation protection – surge limiting module

Exchangeable surge limiter module MOD. ESM T2 PV 600/20 S is a key element in protecting photovoltaic installations from the effects of lightning strikes and fast voltage transients. Designed for use with PV systems, it protects inverters, panels and other sensitive components from damage. This is particularly important in areas prone to frequent storms or near sources of electromagnetic interference.

Construction and application

The surge arrester type T2, which this module is, provides indirect protection against overvoltages. This means that it does not directly absorb a lightning strike, but effectively dissipates the energy of overvoltages that have passed through other protections (e.g. type T1 arresters). The modular design allows for quick replacement of a damaged element without the need to disassemble the entire housing. This makes servicing simple and fast, minimizing system downtime. Designed for mounting on a TH35 rail, which facilitates integration with existing electrical infrastructure.

Key features and benefits

• Overvoltage protection: Protects photovoltaic installation components from damage caused by sudden voltage increases.
• Modular design: Enables quick and easy replacement in the event of a failure, reducing system downtime.
• Discharge current 20 kA: Provides effective protection even with strong overvoltages – this value determines the arrester's ability to dissipate energy during discharge.
• Rated voltage 600 V DC: Designed to operate in photovoltaic installations with a DC voltage of up to 600V.
• Optical indication: An optical indicator informs about the operation of the arrester, which facilitates diagnostics and maintenance.
• Compliance with standards: The product meets safety requirements, ensuring reliable protection and compliance with regulations.
• Compact dimensions (1 module): Allows for easy integration with existing switchboards and enclosures.
• Made of high-quality materials: Guarantees durability and reliable operation in various environmental conditions.

This surge arrester is an investment in the long-term stability and safety of your photovoltaic installation – for both professional installers and end users.
