scope:
The scope of IEC 61008-1 and IEC 61009-1 applies.
This standard specifies requirements and tests for type B RCDs. Requirements and tests given in this standard are in addition to the requirements of type A residual current devices.
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 in case of three phase supply.
Type B RCCBs and Type B RCBOs 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 or Annex B of this standard.
The complete test sequence for type test of Type B RCCBs and Type B RCBOs is given in Tables A.1 or B.1.
NOTE 1 Throughout the document, the term RCD refers to RCCBs and RCBOs.
NOTE 2 Requirements for 1 pole and 2 poles are under consideration.
