Surge arrester T1, T2 (B, C) - spark gap ETITEC GSM T12 440/35 1+0 RC 002440717

Electrical installation protection with ETITEC GSM T12 surge limiters

The ETITEC GSM T12 440/35 1+0 RC surge arrester is a reliable element protecting electrical installations from the effects of atmospheric and switching surges. Designed based on spark-gap technology, it effectively protects electrical and electronic devices, minimizing the risk of failures and downtime. It is a class 1+2 device, which means it provides protection against both direct and indirect lightning strikes.

Construction and application

This arrester finds application in TN, IT, TN-S and TN-C network installations. Its compact size – only 2 modules – allows for easy mounting on a DIN TH-35 mm mounting rail, even in limited space of the switchgear. It has optical indication of operation, which facilitates quick identification of damage and the need for replacement. Additionally, it is equipped with a signaling contact, which enables remote monitoring of the device status. The impulse current level of 35 kA guarantees effective protection even with strong surges.
