5 Introduction RCCBs and RCBOs designed according to IEC and IEC are suitable in most of the applications. IEC and provide appropriate requirements and tests for general use in household and similar uses. However, the use of new electronic technology in equipment may result in particular residual currents not covered in IEC or IEC This standard covers specific applications where additional requirements and testing are needed. This Standard includes definitions, additional requirements and tests for Type F and Type B RCCBs and/or RCBOs to cover particular situations. The tests shall first be applied according to IEC for Type F or Type B RCCBs and according to IEC for Type F or Type B RCBOs. After completion of the tests given either in IEC or IEC the additional tests given in this standard shall be applied in order to show conformity to this Standard (see Appendix A, Appendix B for Type F or Appendix C, Appendix D for Type B respectively). The number of samples to be submitted and test sequences to be applied for verification of conformity for Type F RCCBs and Type F RCBOs are given in Appendix A and Appendix B respectively. The number of samples to be submitted and test sequences to be applied for verification of conformity for Type B RCCBs and Type B RCBOs are given in Appendix C and Appendix D respectively. This Standard introduces Type F RCDs (F for Frequency) with rated frequency 50 Hz or 60 Hz intended for protection of circuits with frequency inverters supplied between phase and neutral or phase and earthed middle conductor taking into account the necessary features for these particular situations in addition to the cases covered by type A RCDs. In case of a frequency inverter, e.g. used for motor speed control, supplied between phase and neutral, a composite residual current including the power frequency, the motor frequency and the chopper clock frequency of the frequency inverter may occur in addition to alternating or pulsating d.c. residual currents. Type F RCDs cannot be used where electronic equipment with double bridge rectifiers supplied from two phases is found or if a smooth d.c. residual current can occur. This standard introduces Type B RCDs to be used in case of residual pulsating rectified direct current which results from one or more phases, and smooth d.c. residual current in addition to the cases covered by Type F RCDs. For these applications, two, three or four pole Type B RCDs can be used. Buy True-PDF Auto-delivery. Page 6 of 40
6 Type F and type B residual current operated circuit-breakers with and without integral overcurrent protection for household and similar uses 1 Scope The scope of IEC and IEC 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 supplemented the requirements of Type A residual current devices. This Standard can only be used together with IEC and IEC 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 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 or IEC 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 Appendix A, Appendix B, Appendix C or Appendix 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. NOTE 1: Throughout this Standard, the term RCD refers to RCCBs and RCBOs. NOTE 2: Requirements for 1 pole with solid neutral are under consideration. Buy True-PDF Auto-delivery. Page 7 of 40
