Surge arrester with disconnector ETITEC A 660/5/C-NO 002441132

Power supply installation protection – reliability and safety

ETITEC A 660/5/C-NO surge protector is a key element in protecting electrical installations from the effects of atmospheric and switching surges. The device, manufactured by ETI POLAM, is designed to protect overhead lines, ensuring uninterrupted power supply and minimizing the risk of equipment damage. The design with a disconnector facilitates the location and elimination of a damaged element after a surge, shortening repair time.

Construction and application

This surge protector utilizes varistor technology, guaranteeing a fast response to sudden voltage increases. Designed for operation in TN network systems, it effectively protects against the effects of disturbances. Protection class II / C indicates its ability to limit surges to a safe level of 2kV. The rated discharge current of 5kA and the short-circuit withstand capacity of 4kA demonstrate its robustness and reliability in harsh operating conditions. Direct mounting simplifies installation, and optical indication of operation facilitates diagnostics.

Key features and benefits

• Effective protection: Protects against atmospheric (lightning strikes) and switching (switching on/off large loads) surges.
• Fast response: Varistor technology ensures a lightning-fast response to voltage increases, minimizing the duration of the disturbance.
• Convenient diagnostics: Optical indication of operation allows for quick identification of a damaged surge protector.
• Easy replacement: The presence of a disconnector facilitates the replacement of a damaged element without the need to disconnect the entire circuit.
• Versatility: Designed for TN network systems, making it compatible with most installations.
• Durability: Rated discharge current of 5kA and short-circuit withstand capacity of 4kA guarantee long-term and reliable operation.
• Safety: Protects electrical equipment from damage, extending its lifespan and reducing repair costs.
• Application in various environments: Ideal for use in industry, commercial and residential construction.

The ETITEC A 660/5/C-NO surge protector is an investment in the safety and continuity of operation of the electrical installation – for both professionals and end users.
