VARIMETER RCM
Residual Current Monitor, Type B for AC and DC Systems
IP 5883
IP 5883
Product Description
The AC/DC sensitive residual current monitor IP 5883 allows an early de-
tection of insulation faults and detects differential currents with AC as well
as DC components in grounded voltage systems (type B). The measure-
ment takes place via an external current transformer.
Contrary to an RCD the residual current monitor IP 5883 does not dis-
connect the mains when detecting a fault but only indicates it. Besides the
easy to read LED chain indicating the actual current several LEDs display
operation, pre-alarm and alarm. The 4 measuring ranges cover 10 to 3 A.
Additional features are broken wire detection, test function and adjustable
pre-alarm.
The residual current monitor IP 5883 provides early information for preci-
se and cost effective maintenance before the plant stops.

Indicators
Green LED "ON":
On, when auxiliary supply connected
Red LED "pre alarm":
Flashes during time delay, on, when pre-alarm
active
Red LED "alarm":
Flashes during time delay, on, when alarm active
Both red LEDs:
Flashing on broken wire or extremely high input
signal
Yellow LEDs:
LED chain indicates fault current in % of adjusted
alarm value
Notes
The devices measure AC and DC current (AC/DC sensitive).Due to the
measuring prinziple they are also influenced by magnetic fields next to
current transformer.
When planning equipment with AC/DC sensitive residual current moni-
tors, components that create magnetic fields as contactors, transformers
etc., should not be placed near to the current transformer. If an influence
cannot be avoided, turning the transformer 90° could reduce the influence.
