The scope of IEC 61008-1 and IEC 61009-1 applies with the following additions.
This standard specifies requirements and tests for Type F and Type B RCDs (Residual
Current Devices). Requirements and tests given in this standard are in addition to the
requirements of Type A residual current devices. This standard can only be used together
with IEC 61008-1 and IEC 61009-1.
Type F RCCBs (Residual Current Circuit Breaker) and Type F RCBOs (Residual current
Circuit Breaker with Overcurrent protection) with rated frequency 50 Hz or 60 Hz are intended
for installations when frequency inverters are supplied between phase and neutral or phase
and earthed middle conductor and are able to provide protection in case of alternating
residual sinusoidal at the rated frequency, pulsating direct residual currents and composite
residual currents that may occur.
Type B RCCBs and Type B RCBOs are able to provide protection in case of alternating
residual sinusoidal currents up to 1 000 Hz, pulsating direct residual currents and smooth
direct residual currents.
RCDs according to this standard are not intended to be used in d.c. supply systems.
Further requirements and tests for products to be used in situations where the residual
current was not intended to be covered in IEC 61008-1 or IEC 61009-1 are under
consideration.
For the purpose of manufacturer’s declaration or verification of conformity, type tests should
be carried out in test sequences in compliance with Annex A, Annex B, Annex C or Annex D
of this standard.
The complete test sequence for type test of Type F RCCBs and Type F RCBOs is given in
Tables A.1 and B.1 respectively. The complete test sequence for type test of Type B RCCBs
and Type B RCBOs is given in Tables C.1 or D.1 respectively.
