Analogue signal/current loop (CL) protection includes the following signals: Signals from current loops (analogue measurements of sensors over long distances) 4 – 20 mA, 0 – 20 mA etc.

Two-wire, three-wire and four-wire, without a common reference potential e.g. level indication signals from voltage sensors (analogue measurements of sensors over short distances) 0 – 10 V, PT 100 etc .

e.g. temperature measurement Pluggable arrester, with interruption-free and impedance-neutral plug-in and pull-out Can be tested with the V-TEST testing device Version with floating-earth PE connection used to avoid differences in potential Can be used in compliance with the IEC 62305 (D1, C1, C2 and C3) installation standard Integrated PE foot safely discharges up to 20 kA (8/20 μs) and 2.5 kA (10/350 μs) to the PE Colour coding of the voltage levels for fast identification on the panel Safety function through coding elements for different voltage levels
