Surge protector with disconnector ETITEC A 500/5/C-NO 002441122

Protection of installations and devices – surge arrester ETITEC A 500/5/C-NO

This surge arrester with a disconnector, from the ETITEC A series, is a key element in protecting electrical installations from the effects of atmospheric and switching surges. Designed to operate in overhead networks, it effectively protects connected devices, minimizing the risk of failures and downtime. This is particularly important in places exposed to frequent lightning strikes or in installations with high sensitivity to interference.

This arrester is used in overhead lines where the impulse withstand voltage of the insulation does not exceed 6kV. Thanks to the use of varistor technology, it provides a quick and effective response to sudden voltage increases. The built-in disconnector indicates the operation of the arrester, making it easier to identify and replace the damaged element.

Key features and benefits

• Effective protection: Protects against atmospheric and switching surges, protecting valuable electrical devices.
• Varistor technology: Ensures a quick response to sudden voltage changes, minimizing the duration of the surge.
• Disconnector: The built-in mechanism disconnects the arrester after operation, signaling the need for replacement and ensuring continuous protection.
• Versatile application: Designed for overhead (bare or insulated) and cable lines.
• Compliance with standards: Meets the requirements of IEC/VDE class II / C, guaranteeing safety and reliability.
• Rated discharge current: 5kA (8/20μs), which demonstrates its ability to dissipate large current pulses.
• Continuous operating voltage (Uc): 500V – matched to typical low-voltage networks.
• Short-circuit current (kA): 4kA - ensures resistance to the effects of short circuits in the installation.
• Network system: Compatible with TN, TN-C and TN-S systems, increasing its versatility.

The ETITEC A 500/5/C-NO arrester is a reliable solution for installers looking for effective surge protection and for end-users who care about the safety of their electrical devices. Direct mounting facilitates integration with existing network infrastructure. A protection level of 1.7kV guarantees a high degree of protection against damage caused by sudden voltage spikes.
