Surge protector with disconnector ETITEC A 500/5/E-NO 002441124

Power supply protection – surge arrester ETITEC A 500/5/E-NO

This surge arrester with a disconnector is a key element in protecting the electrical installation from the effects of atmospheric and switching surges. Designed to protect overhead lines, it effectively protects devices and ensures uninterrupted power supply. Its construction based on varistor technology guarantees a quick and effective response to sudden voltage changes.

Construction and application

The ETITEC A 500/5/E-NO surge arrester is designed for direct mounting in TN, TN-C and TN-S networks. Its task is to limit the surge voltage to a safe level, protecting connected receivers from damage. It has a built-in disconnector that optically signals the operation of the device, making it easier to identify the location of the surge. This allows the installer to quickly locate and remove the cause of the problem, and the end user can be sure that their installation is monitored.

• Rated voltage Uc is 500V, ensuring compatibility with most electrical networks.
• Rated discharge current (8/20μs) is 5kA, determining the ability to dissipate energy during atmospheric or switching discharge.
• Protection level Up at 1.7kV indicates the effectiveness of the arrester in reducing the surge voltage to a safe level.
• Short-circuit withstand capacity (Isccr) is 4kA – an important parameter for installers, determining resistance to short-circuit currents occurring in the network.
• Varistor technology used ensures a fast response and high efficiency in suppressing surges.
• Compatible with TN, TN-C and TN-S networks – versatility of application in various electrical network configurations.
• Optical signaling facilitates diagnostics and location of the arrester activation point.

This arrester finds application in both domestic and industrial installations, where protection against surges is particularly important to ensure the reliable operation of electrical and electronic devices. Thanks to its construction and technical parameters, it provides reliable protection against the effects of uncontrolled voltage increases.
