Surge arrester with disconnector ETITEC A 500/5/B-NO 002441121

Surge protector ETITEC A 500/5/B-NO – protecting the power supply installation

This surge protector with a disconnector, from the ETITEC A series, is a key element ensuring safety and reliability in low-voltage networks. Designed by ETI POLAM, it protects sensitive devices from the effects of atmospheric and switching surges. Its primary application is to protect overhead lines, but it will also work well in installations where there is an increased risk of interference.

This surge protector is particularly useful in places where a quick response to sudden voltage increases is required – while minimizing the risk of unnecessary circuit disconnection. Thanks to the presence of a disconnector, after the surge protector has operated, it is possible to quickly locate and remove the damage without having to interrupt the power supply to the entire network.

### Construction and application

The ETITEC A 500/5/B-NO surge protector is designed for mounting on overhead low-voltage lines. Its construction allows for effective dissipation of surge energy to the ground, minimizing the risk of damage to connected devices. Piercing bilateral terminals facilitate installation and ensure a secure connection with the conductors. The protection class it provides ensures effective protection against the effects of lightning strikes and surges generated during switching operations in the network.

* **Application:** Protection of overhead low-voltage lines, protection of electrical devices against surges.

• Construction: Made of durable materials resistant to weather conditions and UV radiation.

• Disconnector: Allows visual identification of the surge protector status after operation and quick replacement of the damaged element.

• Terminals: Piercing bilateral terminals ensure easy and secure mounting on conductors.

### Key features and benefits

The ETITEC A 500/5/B-NO surge protector is not only a protective element, but also an investment in the long-term reliability of the electrical installation. Its solid construction and high quality workmanship guarantee a long service life and minimal operating costs. For installers, this means easy installation and confidence in proper operation, and for end-users – peace of mind and protection of valuable electrical devices.
