Residual Current Operated Circuit-Breakers with Integral Overcurrent Protection for Household and Similar Uses (RCBOs) - Part 1: General Rules
Also Known As:
The IEC 61009-1:2010+A1:2012 standard applies to residual current operated circuit breakers with integral overcurrent protection for household and similar uses. These devices are designed to protect against electrical faults by detecting and interrupting excessive current flows. The standard specifies requirements for RCBOs with rated voltages up to 440 V AC and rated currents up to 125 A, with a maximum rated short circuit capacity of 25,000 A.
The third edition of the standard includes several technical changes compared to the previous edition. These changes include a complete revision of the electromagnetic compatibility (EMC) sequences, clarification of the current/time characteristics of RCBOs, revised test procedures for rated currents between 5 A and 200 A, and new tests for the use of RCBOs in IT systems. The standard also addresses testing procedures for the superimposition of a 6 mA direct current (DC) to the fault current and provides improved guidelines for RCBOs with multiple sensitivity levels.
The standard aligns with IEC 60898-1, which specifies requirements for circuit breakers for overcurrent protection in household and similar installations. The consolidated version of the standard includes the third edition and its amendment 1, eliminating the need to order the amendment separately.
