IEC 60755-2017 pdf free.General safety requirements for residual current operated protective devices.
This document provides general minimum requirements, recommendations and information for the drafting of standards on residual current operated protective devices (hereinafter referred to as residual current devices. “RCDs). It applies to any device providing residual current protection intended primarily for protection against electric shock hazard.
NOTE 1 Residual current monitors (RCMs) according to IEC 62020. whose purpose Is to monitor an electrical installation and not to provide protection. are not covered by this document and cannot be considered similar or equivalent to RCDs.
NOTE 2 RCDs for DC supply system are under consideration.
NOTE 3 For the relationship between this document and the RCD product standards, see Annex D.
This document is primarily intended to be used as a reference for drafting product safety standard for devices identified as “RCD” or “residual current device” either for general use or incorporated or embedded in equipment.
This document is also intended to be used as a reference for defining the design requirements and the applicable testing procedure for an RCD incorporated or embedded in an equipment.
This basic safety publication is primarily intended for use by technical Committees in the preparation of standards in accordance with the principles laid down in IEC Guide 104 and ISO/IEC Guide 51. It is not intended for use by manufacturers or certification bodies.
One of the responsibilities of a technical committee is, wherever applicable, to make use of basic safety publications in the preparation of its publications. The requirements, test methods or test conditions of this basic safety publication will not apply unless specifically referred to or included in the relevant publications.
