Overview

Surge arrester 4P T2 TNS/TT backup fuse up to 315A In 20kA Imax 40kA. 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 signal on the plugs in the event of overload. Connections for the active conductors from below and for earth/PE from above. Biconnect terminals for connecting round conductors and wiring bridges. Labeling option on the base element.
