Modular surge arrester ETITEC ESM T2 PV 1200/20 Y RC 002440681

Photovoltaic installation protection – surge arrester ETITEC ESM T2 PV 1200/20 Y RC

This modular surge arrester is specifically designed to protect photovoltaic (PV) installations from the effects of overvoltages, both atmospheric (lightning strikes) and switching. It provides effective protection for sensitive electronics in PV systems, minimizing the risk of failure and downtime. It is a key element ensuring the reliability and longevity of the entire installation.

Construction and application

The ETITEC ESM T2 PV 1200/20 Y RC surge arrester is a Type 2 device, which means it is intended for installation in the main or sub-distribution board, to protect against overvoltages that have passed through the first stage of protection (e.g. Type 1 arrester). Its modular design simplifies installation and replacement in case of damage. The built-in RC signaling contact informs about the need to replace the arrester after activation, which increases safety and allows for a quick response. Designed to operate with direct current (DC) voltage typical of photovoltaic installations.

Key features and benefits

• High energy discharge capacity: Rated discharge current of 20 kA and maximum discharge current of 40 kA guarantee effective protection even with strong overvoltages.
• Adapted to photovoltaic systems: Specifically designed to operate with DC voltage of 1200V, typical for PV installations.
• Status indication: Built-in RC signaling contact informs about arrester damage, enabling quick replacement and maintaining continuous protection.
• Modular construction: Simplifies installation, replacement and integration with the existing electrical installation.
• Safety and reliability: Provides effective protection against overvoltages, minimizing the risk of equipment damage and failure of the photovoltaic system.
• Versatility: Suitable for both new installations and modernization of existing PV systems.
• Compliance with standards: Meets safety standards, ensuring compliance with applicable regulations.

Thanks to these features, the ETITEC ESM T2 PV 1200/20 Y RC surge arrester is a reliable element of photovoltaic installation protection, protecting the investment and ensuring its long-term performance. Installing this type of arrester is an investment in peace of mind for both the installer and the end user of the PV system.
