Hager surge arrester SPB413: Additional details
Surge arrester T2 4P 40kA TT/TN-S fault indication. 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 a dynamic disconnection device. Optical fault indication on the plugs in case 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.
