5.5 Testing RCDs
Various test and measurements are required for verification of RCD(s) in RCD protected
installations. Measurements are based on the EN 61557-6 standard.
The following measurements and tests (sub-functions) can be performed:
 contact voltage,
 trip-out time,
 trip-out current and
 RCD auto-test.
See chapter 4.2 Function selection for
instructions on key functionality.

Ulim
Conventional touch voltage limit [25 V, 50 V].
* Model MI 3102 BT only
Notes:
 Ulim can be selected in the Uc sub-function only.
 Selective (time-delayed) RCDs have delayed response characteristics. As the contact
voltage pre-test or other RCD tests influence the time delayed RCD it takes a certain
period to recover into normal state. Therefore a time delay of 30 s is inserted before
performing trip-out test by default.
 Portable RCDs (PRCD, PRCD-K and PRCD-S) are tested as general (non-delayed)
RCDs. Trip-out times, trip-out currents and contact voltage limits are equal to limits of
general (non-delayed) RCDs.
 The a.c. part of MI and EV RCDs is tested as general (non-delayed) RCDs.
 The d.c. part of MI and EV RCDs is tested with a d. c. test current. The Pass limit is
between 0.5 and 1.0 IdN
