Surge protector with disconnector ETITEC A 280/5/A-NO 002441100

Surge protection for low voltage networks

The ETITEC A 280/5/A-NO surge arrester is a reliable element protecting electrical installations from the effects of lightning strikes and overvoltages in low-voltage networks. Designed for installation on overhead lines, it effectively protects devices and infrastructure from damage. Equipped with a disconnector, it allows for visual monitoring of the status after operation.

Construction and application

This surge arrester from the ETITEC A series, manufactured by ETI POLAM, uses varistor technology for fast and effective suppression of overvoltages. It is designed for TN network systems, providing protection in various configurations (TN-C, TN-S). With a protection level of 0.9kV, it effectively limits the voltage to a safe level. Application in overhead lines makes it an ideal solution for protecting distributed electrical installations, e.g. in rural areas or industrial facilities.

Key features and benefits

• High efficiency: Rated discharge current of 5kA and the ability to withstand short-circuit current of 4kA guarantee effective protection against even strong overvoltages.
• Visual indication: Optical indication of operation facilitates quick identification of a damaged arrester and the need for replacement.
• Versatility: Possibility of use in various TN network systems (TN-C, TN-S) increases the range of applications.
• Durability and reliability: The use of varistor technology and a solid construction ensure long-lasting and trouble-free operation of the device.
• Safety: The disconnector allows for safe disconnection of the damaged arrester from the network.
• Installation: Designed for direct mounting on the overhead line, which simplifies installation and reduces costs.
• Leakage current: It has a leakage current function, which increases safety.

The ETITEC A 280/5/A-NO arrester is an investment in the safety of your electrical installation and peace of mind. It provides reliable protection against the effects of overvoltages, minimizing the risk of failures and costly repairs.
