Test Standard
The following must be substantiated per
DIN VDE 0100-600:2008:
– Touch voltage occurring at nominal residual current may not
exceed the maximum allowable value for the system.
– Tripping of the RCCB must occur within 400 ms (1000 ms for
selective RCDs) at nominal residual current.
Important Notes
•The PROFITEST INTRO permits simple measurements at all
types of RCDs. Select RCD, SRCD, PRCD etc.
• Measurement must be executed at one point only per RCD
(RCCB) within the connected electrical circuits. Low-resis-
tance continuity must be substantiated for the protective con-
ductor at all other connections within the electrical circuit (R
LO
or U
B
).
• The measuring instruments often display 0.1 V touch voltage
in TN systems due to low protective conductor resistance.
• Be aware of any bias currents within the system. These may
cause tripping of the RCDs during measurement of touch volt-
age U
B
, or may result in erroneous displays for measurements
with rising current: Display = I

• Selective RCDs identified with an can be used as the sole
means of protection for automatic shutdown if they adhere to
the same shutdown conditions as non-selective RCDs (i.e.
t
a
< 400 ms). This can be substantiated by measuring break-
ing time.
• Type B RCDs may not be connected in series with type A or F
RCDs.
Note
Bias Magnetization
Suppression of RCD tripping by means of bias magneti-
zation with direct current is only possible via a country-
specific measuring adapter, e.g. PRO-Schuko measuring
adapter (Z503K) or the KS-PROFITEST INTRO (Z503L) for
3-pole measurement.
