Surge arrester with disconnector ETITEC A 660/5/E-NO 002441134

Protection of installations and devices – surge arrester ETITEC A 660/5/E-NO

Surge arrester ETITEC A 660/5/E-NO is a reliable element for protecting electrical installations against the effects of current surges and atmospheric overvoltages. Designed for use in TN, TN-C and TN-S networks, it effectively protects devices from damage caused by sudden voltage increases. The design with a disconnector facilitates diagnostics and quick replacement in case of operation.

Construction and application

This arrester utilizes varistor technology, ensuring a fast response to overvoltages. It is intended for the protection of overhead lines, and its direct mounting simplifies installation. Protection class II/C (IEC/VDE) guarantees a high level of safety. The device signals its operation optically, which facilitates problem identification.

• Rated discharge current: 5kA (8/20μs) – provides effective protection against typical lightning strikes.
• Continuous operating voltage (Uc): 660V – enables use in a wide range of installations.
• Protection level (Up): 2kV – minimizes the risk of damage to connected devices.
• Short-circuit current: 4kA – determines the ability to withstand a short circuit without damage.
• Maximum discharge current: 40kA – indicates the ability to dissipate large amounts of energy during overvoltages.

Advantages for the installer and end user

• Quick installation: Direct mounting saves time during installation.
• High reliability: Varistor technology and protection class II/C ensure long-lasting and effective protection.
• Visual signaling: Optical signaling of operation facilitates diagnostics and problem location.
• Versatility of application: Possibility of use in various network configurations (TN, TN-C, TN-S) increases flexibility of application.
• Protection against damage: Protects electrical devices from overvoltages, which translates into savings and avoidance of downtime.
• Safety: Protects the electrical installation from the effects of current surges and atmospheric overvoltages, minimizing the risk of fire or electric shock.

The ETITEC A 660/5/E-NO surge arrester is a solid solution for anyone who cares about the safety of their electrical installation and sensitive electronic devices. Its versatility and ease of installation make it an ideal choice for both professionals and end users looking for reliable surge protection.
