Hager Surge Arrester SPB415: additional details
Surge arrester T2 4P 40kA TT/TNS fault indication + contact. Type 2 surge arrester in a 3+1 configuration, designed to protect three-phase TT and TN-S systems. Comprising a fourfold base element, three protective plugs with temperature-monitored high-performance varistors, and one plug as a total current spark gap with dynamic disconnection device. Optical fault indication on the plugs in case of overload. Changeover contact for remote fault indication. Connections for the active conductors from below, for ground/PE and remote signaling contact from above. Biconnect terminals for connecting round conductors and wiring bridges. Labeling option on the base element.
