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 Part of 2,116,917.

This section identical with IEC 61009-2-1:1991 "household and similar uses overcurrent protection for residual current operated circuit breaker (RCBO) Part 2.1. General rules for the operation of the functions independent of 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 16917.21-1997, the main difference between this part and GB 16917.21-1997 follows.

--- The whole standard "line voltage" to "supply voltage";

--- Chapter 6 "o) Item" to "n) term." 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.
