Reviews

Surge arrester T2 3P 40kA TNC defect indication + contact. Type 2 surge arrester in 3+0 circuit, for protecting three-phase TN-C systems. Consists of a triple base element and three protective plugs with temperature-monitored high-performance varistor with 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.
