Foreword

All technical content in this section is mandatory.

GB 16917 "household and similar uses overcurrent protection for residual current operated circuit breaker (RCBO)" into the following sections.

--- Part 1. General rules;

--- Part 21. General rules for the operation of the functions independent of line voltage RCBO the applicability;

--- Part 22. General rules for the operation of the function and line voltage RCBO applicability.

This section GB 16917 of Part 22.

This section identical with IEC 61009-2-2:1991 "household and similar uses overcurrent protection for residual current operated circuit breaker (RCBO) Part 2.2. General rules for the operation of the function and line voltage RCBO the applicability. " it should be used and GB 16917.1-2003 "with this household and similar uses overcurrent protection for residual current operated circuit breaker (RCBO) - Part 1. General rules "together.

This Part replaces GB 16917.22-1997, and GB 16917.22-1997 main differences are as follows.

--- The whole standard "line voltage" to "supply voltage." this part is proposed by the China Electrical Equipment Industrial Association.

The low-voltage electrical part by the National Standardization Technical Committee (SAC/TC189) centralized.
