Surge protector with disconnector ETITEC A 280/10/A-NO 002441140

Protection of the power supply system – surge arresters ETITEC A

The ETITEC A 280/10/A-NO surge arrester is a key element in protecting low-voltage networks from the effects of current surges, caused, for example, by lightning strikes. This device, designed for aerial mounting, effectively protects sensitive equipment from damage and ensures uninterrupted power supply. Thanks to the built-in disconnector, it indicates the blown state and facilitates fault location.

Construction and application

This arrester is part of the ETITEC A series from ETI POLAM, known for its reliability and high-quality components. It is intended for the protection of overhead low-voltage lines, especially where protection against overvoltage is required in outdoor conditions. The design with a disconnector allows for visual control of the device's status after a surge – which is particularly important during network inspections and maintenance.

Advantages and benefits

• Effective protection: Protects electrical equipment from the harmful effects of overvoltage, extending its lifespan and minimizing the risk of failure.
• Visual indication: The built-in disconnector informs about the need to replace the arrester after a surge – facilitates diagnostics and shortens repair time.
• Aerial mounting: Enables quick and easy installation on overhead lines without the need for complex tools or procedures.
• Durable construction: Ensures reliable operation in harsh weather conditions – resistance to moisture, UV radiation and temperature changes.
• Simple diagnostics: The disconnector facilitates quick identification of a faulty arrester during inspections and network maintenance.
• Application in bare lines: Eliminates the need for additional insulating covers on the terminals, simplifying installation and reducing costs.

The ETITEC A 280/10/A-NO arrester is an investment in the safety and reliability of the electrical installation – both for the end user and for the installer responsible for its proper functioning.
