Surge arrester without disconnector ETITEC A 660/10/S-N 002442715

Surge arrester – protection of installations and devices

The ETITEC A 660/10/S-N surge arrester is a key element in protecting electrical installations from the effects of voltage surges. The device effectively protects against overvoltages that can damage connected receivers, such as electronic equipment or industrial devices. Using a surge arrester is an investment in the reliability and durability of the system.

Construction and application

This arrester uses varistor technology, which ensures a quick and effective response to sudden voltage increases. It is designed to protect overhead lines in TN, TN-C and TN-S network systems. Protection class II / C (according to IEC/VDE) guarantees a high level of safety. The device is single-pole and designed for direct mounting.

Key parameters and benefits

• Operating voltage Uc: 660V – enables use in a wide range of electrical installations.
• Nominal discharge current In (8/20μs): 10kA – provides effective protection against impulsive overvoltages.
• Rated short-circuit current (kA): 4kA – resistance to short-circuit currents, which increases installation safety.
• Protection level Up: 2.05kV – low protection level, minimizing the risk of damage to connected devices.
• Varistor technology: fast reaction to overvoltages, ensuring optimal protection.
• Optical indication of operation: informs about the need to check the device status after a surge occurs.
• Leakage current: the presence of leakage current indicates the correct operation of the arrester and its ability to dissipate surge energy to ground.

The ETITEC A 660/10/S-N surge arrester is a reliable solution for installers and users looking for effective protection against the effects of overvoltages in the electrical network. Its solid construction and high parameters ensure long-term and safe operation.
