Foreword

This Standard was drafted as per the rules specified in GB/T 1.1-2009.

This Standard replaced GB/T 22794-2008 Type B Residual Current Operated Circuit-

Breakers with and without Integral Overcurrent Protection for Household and Similar

Uses (Type B RCCBs and Type B RCBOs). Compared with GB/T 22794-2008, this

Standard has the major changes as follows.

--- Modified the introduction.

--- Modified the scope, this standard covers Type F RCD.

--- Added the definition of Type F residual current device in 3.2.

--- Supplemented the according to behavior in presence of d.c. components in 4.1.

--- Supplemented the characteristics of Type F residual current device in 5.1.

--- Modified and supplemented the characteristics of Type B residual current device

in 5.2.

--- Added Type F RCD sign in 6.1.

--- Modified Type B RCD sign in 6.2.

--- Added Type F and Type B RCD requirements in 8.1.

--- Supplemented the characteristics of three-pole and four-pole Type B RCD in the

case of two-pole power supply only in 8.2.1.7.

--- Added the RCD performance under the role of surge residual current in 8.3.1;

the RCD performance under the role of in-rush residual current in 8.3.2; the

performance when pulsating direct residual current superimposes 10mA

continuous smooth direct residual current in 8.3.3.

--- Added Type F and Type B RCD tests in 9.1.

--- Supplemented the correct operation of three-pole and four-pole Type B RCD

when only powered by two-pole in 9.2.3.

--- Added an example of a test circuit to verity proper operation when single-phase

supply motor speed control device generates residual sinusoidal AC current with

multiple frequency components in Figure 1.

--- Added a test circuit to verify RCD performance when in-rush current occurs in

Figure 2.

--- Added Appendix A Quantity of Specimens and Test Procedures for Type F RCCB

Compliance Verification; and Appendix B Quantity of Specimens and Test

Procedures for Type F RCBO Compliance Verification.

--- Modified Appendix C Quantity of Specimens and Test Procedures for Type B

RCCB Compliance Verification; and Appendix D Quantity of Specimens and Test

Procedures for Type B RCBO Compliance Verification.

--- Modified Appendix E Type F and Type B RCD Routine Tests.

The translation method of this Standard equivalently adopts IEC 62423.2009 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 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 supplemented

the requirements of Type A residual current devices. This Standard can only be used

together with IEC 61008-1 and IEC 61009-1.

dated documents, only the versions with the dates indicated are applicable to this

document; for the undated documents, only the latest version (including all the

amendments) are applicable to this document.

General Aspects

3 Terms and Definitions

For the purposes of this document, the following terms and definitions apply.

residual current device for which tripping is ensured as for Type F according to this

Standard and in addition.

4 Classification

According to IEC 61008-1 or IEC 61009-1, as applicable with the following addition.

5 Characteristics

Residual current device for which tripping is ensured as for Type F and in addition.

6 Marking and Other Product Information

Add the following symbol adjacent to the symbol for Type A, e.g.

; alternatively, the following symbol may be used.

7 Standard Conditions for Operation in Service and for Installation

According to IEC 61008-1 or IEC 61009-1, as applicable.

8 Conditions for Construction and Operation

RCDs shall show adequate resistance against unwanted tripping in case of current

surges to earth due to the loading of the capacitances of the installation and the current

surges to earth due to flashover in the installation.

RCDs shall adequately withstand inrush residual currents with a maximum duration of

10 ms which can occur in case of switching on electronic equipment or EMC-filters.

9 Tests

Tests are carried out to verify the break time of the RCD, the test current being

calibrated at 5 times the upper limit value given in Table 4.

The test switch S1 and the RCD being in the closed position, the residual current is

suddenly established by closing the test switch S2.
