Portable Residual Current Device-Switched
PRCD-S IP 54
Description
The PRCD-S residual current monitoring device is used as a distributor for, amongst other things,
small construction sites in accordance with trade association requirements. It increases operating
safety at the construction site by providing additional monitoring of the fault current and the
protective earth conductor when the distributor is connected to a TN-type supply grid.
Error Conditions
The PRCD-S residual current monitoring device recognises the following errors on the supply end:
external or neutral conductor interrupted,
not connected
external and PE conductor switched
PE conductor interrupted, not connected
PE conductor interrupted during operation
PE conductor carries dangerous voltage
undervoltage

Notes
1. The PRCD-S residual current monitoring device is a distributor for small construction sites
based on E DIN IEC 62335 and the requirements of BGI 608 of the Energy Textile Electrics pro-
fessional association. The trade association recommends SPE-PRCDs as an effective protection
for small construction sites and portable electrical appliances; the residual current monitoring
device serves as a distributing point for small construction sites in accordance with BGI.
2. These residual current monitoring devices are subject to repeat tests and one-time tests
(after each modification) in accordance with German trade association regulation BGV A3;
because they use PE monitoring and separation, the protective conductor current is measured
instead of insulation resistance in accordance with VDE 0702-1, section 4.3.4.
All repeat and one-time tests must include a functional test that comprises the detection
of all error conditions (see above).
The ground fault circuit interrupter must be tested regularly in accordance with its label.
3. The standard rules of electrical engineering must be observed.
4. Subject to technical modifications without prior notice.

Dangerous voltage on the PE conductor (e.g., because of an installation error) is detected by
measuring the touch current generated by the difference of potential between the PE connection of
the PRCD-S and the on-site protective earth conductor. The principle of measurement used is similar
to that of a phase comparator. Voltage up to a total resistance R
28 MΩ is considered dangerous; the touch current for R

The START button must always be pressed with a bare hand because otherwise
it is difficult or even impossible to recognise dangerous voltage on the
PE conductor.
How to Test the "Detect Dangerous Voltage on PE" Feature
A suitable isolating transformer must be used to avoid endangering the person carrying out the test.
