Surge arrester without disconnector ETITEC A 500/10/EK-N 002442840

Protection of electrical installations against overvoltage

The ETITEC A 500/10/EK-N surge limiter is a protective element that protects the electrical installation from the effects of sudden voltage increases. This is particularly important in places exposed to lightning strikes or in the event of frequent voltage fluctuations in the grid. The design without a disconnector makes these limiters suitable for everywhere where a quick reaction to overvoltage is required, and a power outage is not acceptable.

Construction and principle of operation

This limiter uses a varistor as a voltage limiting element. A varistor is an electronic component characterized by non-linear resistance - it behaves like an insulator at normal voltage, and when the rated voltage threshold is exceeded, its resistance drops sharply, dissipating excess energy to ground. Thanks to this, ETITEC surge limiters effectively suppress overvoltages, protecting connected devices from damage. The rated voltage AC 50 Hz is 500V.

Application and benefits

• Protection against damage: Protects sensitive electronic devices from damage caused by overvoltage.
• Fast reaction: The design without a disconnector ensures an immediate reaction to overvoltage, minimizing the duration of interference.
• Simple installation: ETITEC limiters are easy to install and do not require complicated settings.
• Application in various installations: Suitable for use in both domestic and industrial installations.
• Compliance with standards: The product meets applicable safety standards (information on specific standards should be verified in the technical documentation).

The ETITEC A 500/10/EK-N limiter is a reliable solution for ensuring electrical safety and protecting valuable equipment. Its compact size allows for easy integration with existing electrical infrastructure.
