1 Scope
The scope of lEC 61008-1 and lEC 61009-1 applies with the following additions.
This standard specifies requirements and tests for Type F and Type B RCDs (ResidualCurrent Devices). Requirements and tests given in this standard are in addition to therequirements of Type A residual current devices. This standard can only be used togetherwith lEC 61008-1 and lEC 61009-1.
Type F RCCBs(Residual Current Circuit Breaker) and Type F RCBOs (Residual currentCircuit Breaker with Overcurrent protection) with rated frequency 50 Hz or 60 Hz are intendedfor installations when frequency inverters are supplied between phase and neutral or phaseand earthed middle conductor and are able to provide protection in case of alternatingresidual sinusoidal at the rated frequency, pulsating direct residual currents and compositeresidual currents that may occur.
Type B RCCBs and Type B RCBOs are able to provide protection in case of alternatingresidual sinusoidal currents up to 1 000 Hz, pulsating direct residual currents and smoothdirect 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 residualcurrent was not intended to be covered in IEC 61008-1 or IEC 61009-1 are underconsideration.
For the purpose of manufacturer’s declaration or verification of conformity, type tests shouldbe carried out in test sequences in compliance with Annex A，Annex B,Annex C or Annex Dof this standard.
The complete test sequence for type test of Type F RCCBs and Type F RCBOs is given inTables A.1 and B.1 respectively.The complete test sequence for type test of Type B RRCCBsand Type B RCBOs is given in Tables C.1 or D.1 respectively.
NOTE 1 Throughout the document, the term RCD refers to RCCBs and RCBOs.
NOTE 2 Requirements for 1 pole with solid neutral are under consideration.
