Three-wire and four-wire measuring bridges

 3 or 4-wire system protection includes the following signals:

• PT100, measuring bridges, DMS sensors, measuring bridges, ...
• Pluggable arrester, for interruption-free and impedance-neutral plug-in and pull-out
• Can be tested with V-TEST testing device
• Space-saving design for up to 4 binary signals
• Version with floating-earth PE connection used to avoid interference currents that result from differences in voltage potential
• For use in compliance with the IEC 62305 and IEC61643-22 (D1, C1, C2 and C3) installation standards
• 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 in the cabinet
• Safety function through coding elements for different voltage levels
