Surge arrester with disconnector ETITEC A 500/5/A-NO 002441120

Surge protection with disconnector – surge arrester ETITEC A 500/5/A-NO

This surge arrester with disconnector, from the ETITEC A series by ETI POLAM, is a key element in protecting low-voltage (LV) networks from the effects of atmospheric and switching surges. It provides protection for equipment and cables in the event of sudden voltage spikes, minimizing the risk of failures and downtime. The design with a disconnector indicates damage and allows for quick problem location.

Construction and application

The arrester is designed for mounting on overhead lines. Its construction allows for effective dissipation of surge energy to the ground, protecting connected receivers. Model 500/5/A-NO is characterized by a rated voltage of 500V and an impulse current withstand level of 5kA. The designation "A-NO" indicates the type of execution – with a disconnector indicating the operating status. This solution is particularly useful in installations requiring continuous power supply and quick fault detection.

Key features and benefits

• Fast response: The arrester reacts instantly to surges, directing them to ground and protecting sensitive devices.
• Status indicator: The built-in disconnector visually informs about the operation of the arrester, facilitating diagnostics and replacement. This saves time during inspections and repairs.
• Durable construction: Made of high-quality materials, it ensures reliable operation in various atmospheric conditions.
• Overhead mounting: Designed for direct mounting on overhead lines, simplifying installation and reducing costs associated with additional mounting elements.
• Application in LV networks: Ideal for protecting overhead lines of low voltage in residential, commercial and industrial buildings.
• Protection against damage: Protects electrical equipment from damage caused by surges, extending their lifespan and minimizing repair costs.
