Weidmüller Surge arrester s

Overvoltage protection. Measuring and controlling without signaling function or function display. The following signals are protected by binary signals (SL - Balanced Load): Switching signals with and without common reference potential 24V, 5V to 60V. Two-wire systems usually have a common reference potential for binary sensors, actuators, and indicators such as limit switches, buttons, position sensors, light barriers, contactors, solenoid valves, signal lamps, etc. Pluggable arrester allows for uninterrupted and impedance-neutral plugging and unplugging. Testable by V-TEST tester. Space-saving design for up to 4 binary signals. Version with ground-free PE connection to avoid interference currents in the event of potential differences. Can be used according to the IEC 62305 and IEC 61643-22 construction standards (D1, C1, C2, and C3). Integrated PE foot conducts up to 20 kA (8/20 μs) and 2.5 kA (10/350 μs) safely to PE. Colored marking of the voltage levels for quick identification in the control cabinet. Safety function by coding element for different voltage levels.
