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
