VARIMETER RCM
Residual current monitor RN 5883 Reliably detect fault currents
The type B (sensitive to all types of current) residual current monitor RN 5883 from
DOLD's VARIMETER RCM family detects fault currents with DC or AC components
in earthed networks. Here, the differential current measurement is implemented via
the ND 5015 external differential current transformer. With an installation depth of
71 mm, the RN 5883 is also suitable for use in installation consumer units and industrial
cabinets.
Residual current monitors (RCMs) measure and monitor differential currents or fault
currents in earthed power supply systems. They are installed in systems in which a
message rather than a shut-down is to be initiated in the event of a fault. In comparison
to residual current breakers (or residual current devices - RCDs), which trip in the
event of a defined fault current being measured and cause an immediate shut-down,
residual current monitors indicate a fault current early and report a degradation of
insulation via an output contact for example.
The early detection of insulation faults along with preventative maintenance and repair
outside operating hours allows unexpected downtimes for machines and systems to
be avoided and this in turn avoids undesirable operational interruptions, property
damage and high costs.
