Overview

Surge arrester T2 4P 40kA TT/TNS defect indication + contact. Type 2 surge arrester in 3+1 circuit, for protecting three-phase TT and TN-S systems. Consists of a four-way base element, three protective plugs with temperature-monitored high-performance varistor and a plug as a total current spark gap with dynamic disconnection device. Optical defect indication on the plugs in the event of overload. Changeover contact for remote defect indication. Connections for the active conductors from below, for earth/PE and remote indication contact from above. Biconnect terminals for connecting round conductors and wiring bridges. Labeling option on the base element.
