Abstract This International Standard applies to residual current operated circuit-breakers with integral overcurrent protection functionally independent of, or functionally dependent on, line voltage for household and similar uses (hereafter referred to as RCBO's), for rated voltages not exceeding 440 V a.c., rated currents not exceeding 125 A for fixed installation and rated short-circuit capacities not exceeding 25 000 A for operation at 50 Hz or 60 Hz. These devices are intended to protect people against indirect contact, the exposed conductive parts of the installation being connected to an appropriate earth electrode and to protect against overcurrents the wiring Installations of buildings and similar applications. They may be used to provide protection against fire hazards due to a persistent earth fault current, without the operation of the overcurrent protective device. RCBO's having a rated residual operating current not exceeding 30 mA are also used as a means for additional protection in the case of failure of the protective means against electric shock. This standard applies to devices performing simultaneously the function of detection of the residual current, of comparison of the value of this current with the residual operating value and of opening of the protected circuit when the residual current exceeds this value, and also of performing the function of making, carrying and breaking overcurrents under specified conditions. NOTES 1. The content of the present standard related to the operation under residual current conditions is based on IEC 1008. The content of the present standard related to protection against overcurrents is based on IEC 898. 2. RCBO's are essentially intended to be operated by uninstructed persons and designed not to require maintenance. They may be submitted for certification purposes. 3 Installation and application rules of RCBO's are given in IEC 364. 4 RCBO's within the scope of the present standard are considered as suitable for isolation (see 8.1.3, 9.7.2, 073 9103 9.12.12.1, 9.12.12.2, 9.12.13.2).
