Foreword
This standard Chapter 5, Chapter 6, Section 8 and Chapter 9 is mandatory, the rest are recommended.
This is equivalent to using the standard IEC 62423.2007 "without household and similar purposes and B residual current operated overcurrent protection broken
A road (B and B type RCCB RCBO) "(first edition) (English).
This standard is technically and IEC 62423.2007 is consistent, only made editorial changes or bug fixes to the following text.
--- deleted international standards foreword, preface to increase the national standards;
--- decimal symbol used in the preparation according to the requirements of national standards has been modified;
--- "IEC 60479-1", "IEC 60479-2", "IEC 61008-1.1996", "IEC 61009-1.1996" was changed to "GB/T 13870.1",
"GB/T 13870.2", "GB 16916.1-2003", "GB 16917.1-2003";
--- numbering of the references;
--- 3.1 The following review will be required to supplement the comments;
3.2 --- following functions, to cancel the "pulsating DC residual current" trip function that has been A residual current device
There, the following should not appear in the original error;
--- Table header and row 1 column 1 of 4, to modify the "residual current (IΔ) is equal to the following values are not time-division driving time and off time
Standard value ", IEC mistaken as the original" residual current (IΔ) ";
--- Table 2, line 4 and the second column, IEC text missing residual operating current value is not "IΔn" at 1000Hz, the root standard adoption
According to IEC 60755/T R.2008 "General requirements for residual current operated protective devices" were added;
After the footnote to Table 2 --- tables required by GB T/1.1 bets placed behind the table, IEC original table 2 is placed in Notes to Table footnotes.
This standard Annex A, Annex B and Annex C is normative.
The standard proposed by China Electrical Equipment Industrial Association.

introduction
According to GB 16916.1 and GB 16917.1 design RCCB and RCBO should be applicable to most situations, however, the use of the device
New electronic technologies may have a specific residual current GB 16916.1 and GB 16917.1 can not be covered.
This standard includes a definition of the type B and type B RCCB RCBO relates to a specific case, the supplementary technical requirements and testing.
RCCB type B should be tested first by GB 16916.1, B RCBO type test press GB 16917.1.
After completion of the test, or the predetermined GB 16916.1 GB 16917.1, should additional tests specified in this standard in order to meet the present description
Standards (see Appendix A, respectively, or Appendix B).
RCCB type B or type B compliance verification RCBO the applicable test procedures and submitted to the number of samples or attached in Appendix A, respectively
Record B.
Smoothing the DC current is unlikely to occur in a single phase power supply with the neutral line. Nevertheless, even if the occurrence of residual smooth direct current,
A three-pole or four-pole residual current circuit breaker, as long as the manufacturer states that the device may be used for single-phase applications.
GB 22794-2008/IEC 62423.2007
Household and similar purposes without overcurrent protection and
B residual current operated circuit breaker
(Type B and Type B RCCB RCBO)
Range 1
GB 16916.1 and scope of GB 16917.1 apply.
This standard specifies the requirements and test methods of the type B RCD. Technical requirements and test methods specified in this standard type A is left
Supplementary device of the residual current technical requirements. B and B type RCCB RCBO at 1000Hz and below alternating sinusoidal residual current ripple
A three-phase DC residual current and residual smooth direct current power supply can provide protection.
This standard type B and type B RCCB RCBO can not be used in DC power systems.
Other technical requirements and test methods are not used or GB 16917.1 GB 16916.1 coated products where the residual current
Under consideration.
Or the manufacturer for verification of compliance statement type test according to the standard test procedure in Appendix A or Appendix B is.
All test procedures B and B type RCCB RCBO type test in Table A. 1 or Table B. 1 below.
Note 1. In the standard throughout, the term "RCD" refers RCCB and RCBO.
Note 2. The 1-pole and 2-pole technical requirements are under consideration.
