The S B-PV model assembled by ETI, is a surge arrester that features a Type 1 over voltage protection and is intended for photovoltaic applications. This device is also built to provide protection against direct and indirect lightning discharges. It is equipped with an enhanced thermal disconnection mechanism, consisting of a rotating barrier and a secure arcing shutdown. Moreover, it has a circuit topology that compose of two V configuration or three Y configuration varistor stages.
