Weidmüller Surge arrester s

Overvoltage protection. Measure, control, and regulate with signal function and function display. The following signals are protected: binary signals (SL - symmetrical load), switching signals with and without common reference potential of 24V, 5V, and up to 60V. Two-wire systems typically have a common reference potential for binary sensors, actuators, and indicators such as limit switches, pushbuttons, position transmitters, photocells, contactors, solenoid valves, and indicator lights. Pluggable arrester allows for interruption-free and impedance-neutral plugging or unplugging. Testable by the V-TEST device. Space-saving design accommodates up to 4 binary signals. Designed with a ground-free PE connection to avoid interference currents in case of potential differences. Applicable according to installation standards IEC 62305 and IEC 61643-22 (D1, C1, C2, and C3). Integrated PE foot safely dissipates up to 20 kA (8/20 μs) and 2.5 kA (10/350 μs) to PE. Colored marking of voltage levels for quick identification in the control cabinet. Safety function includes a coding element for different voltage levels.
