1.11 Product description
There is an increasing use of residual current circuit breakers in industry for personal
safety and fire protection. Modern components used in automation technology generate
leakage currents when the system is operating. These so-called “operational” leakage
currents are interpreted by the RCDs as differential currents and thus often lead to
unreliable operating states or to their complete shutdown. The residual current circuit
breaker cannot distinguish between the operational leakage currents and true fault
currents.
The EPA LEAKCOMP
®
1C compensates capacitive currents with a frequency of 50 Hz,
which occur due to EMC filtering of single-phase consumers (such as those that occur
with power supplies, frequency converters, UPSs, lamps, mains filters, etc.)
The LEAKCOMP
®
1C leakage current compensation unit is used in electrical plants,
machines or devices that cause 50 Hz leakage currents and are to be operated on
residual current circuit breakers (RCCBs).
The LEAKCOMP
®
1C compensates for the leakage currents occurring with single-phase
consumers during operation preventing inadvertent or ‘nuisance’ tripping of residual
current devices caused by excessively high 50 Hz leakage currents. The device works
with all common RCCBs of the types A, F, B and B+ (ideally with short-term delay; a
suitable type must be chosen according to the regulations!).
The size of the 50-Hz-compensation current is set at 5 mA and can be increased to 11 mA
via a jumper. If the compensation current is not sufficient to compensate for the leakage
current, additional LEAKCOMP
®
1C devices can be connected in parallel.
The LEAKCOMP
®
1C has two LED indicators.
The blue LED functions as the operating display and indicates the presence of the power
supply and fault-free operation. Reversed phase and neutral conductors, high neutral
conductor voltage (potential difference between neutral and protective earth conductor) or
the absence of the protective earth conductor on the LEAKCOMP
®
1C is indicated by the
red LED.
IMPORTANT NOTE
Along with 50 Hz leakage currents, leakage currents of other frequencies can also
occur that are not compensated by the LEAKCOMP
®
1C. EPA also offer a suitable
solution for these cases.
For leakage current measurement with analysis of the utilisation of the residual
current circuit breaker, we recommend using the leakage current analysis system
EPA LEAKWATCH (more information at www.leakwatch.de).
