Surge protector without disconnector ETITEC A 280/10/C-N 002441147

Overvoltage protection in overhead installations

The ETITEC A 280/10/C-N surge arrester is a component designed to protect electrical installations from the effects of voltage surges, especially in overhead lines. Its task is to discharge excess energy to the ground, protecting connected devices from damage. It utilizes varistor technology, which ensures a fast and effective response to overvoltages.

Construction and application

The arrester's construction is based on proven varistor technology, ensuring reliable operation. Designed for operation in TN, TN-C and TN-S network systems, making it a universal solution for various installations. This arrester is primarily used to protect overhead lines, but due to its parameters it can also be used in other areas requiring protection against overvoltages. It is worth noting its compact size and the possibility of direct mounting – this facilitates integration with existing infrastructure.

Key features and benefits

• High protection efficiency: Rated discharge current of 10kA (8/20μs) and maximum discharge current of 50kA provide effective protection against even strong overvoltages.
• Versatility: Designed for operation in TN, TN-C and TN-S network systems, which increases its scope of application.
• Fast response: Varistor technology guarantees a lightning-fast response to overvoltages, minimizing the risk of damage to connected devices.
• Optical indicator: Has an optical indication of operation, which facilitates identification of an emergency situation and a quick response.
• Short-circuit protection: Short-circuit current at 4kA provides additional safety for the installation.
• Operating voltage: Continuous operating voltage (Uc) is 280V, and rated AC voltage is 230V – parameters adapted to standard power grids.
• Protection class: The class C arrester allows it to react more slowly to short current surges, therefore it tolerates starting devices with a motor well.

The ETITEC A 280/10/C-N surge arrester is a solid and reliable solution for anyone who cares about the safety of their electrical installation and the devices connected to it. Its versatility and high efficiency make it an ideal choice for both professionals and end-users looking for comprehensive overvoltage protection.
