Surge arrester without disconnector ETITEC A 500/5/B-N 002441126

Electrical installation protection with surge arresters ETITEC A

The ETITEC A 500/5/B-N surge arrester is a key element in protecting electrical installations from the effects of lightning strikes and overvoltages. This device, manufactured by ETI POLAM, is designed for use in overhead low-voltage lines. Its task is to quickly dissipate excess energy to the ground, protecting connected devices and infrastructure from damage. The lack of a disconnector in this model means that after the surge arrester operates, the circuit is not automatically disconnected – which may be preferred in applications where power continuity is a priority.
