Surge arrester T1, T2 (B, C) - spark gap ETITEC GSM T12 275/25 4+0 RC 002440609

Electrical installation protection with ETITEC GSM T12 surge limiters

The ETITEC GSM T12 275/25 4+0 RC surge arrester is a reliable element protecting the electrical installation from the effects of atmospheric and switching surges. Designed to work with TN-S networks, it provides effective protection of electrical and electronic devices, minimizing the risk of failures and costly repairs. Its spark-gap technology guarantees a quick response to sudden voltage increases.

### Construction and application

This arrester is classified as a Class 1+2 (T1+T2) device, which means it effectively eliminates both direct and indirect effects of lightning strikes. Mounting is done on a DIN TH-35 mm mounting rail, which facilitates integration with the existing electrical infrastructure. It is intended for protection in TN-S network systems, and its versatility allows it to be used in a wide range of facilities – from residential buildings to industrial plants. The integrated signaling contact informs about the need to replace the device after activation, which increases the safety and reliability of the system.
