IEC 60934:2019 is available as IEC 60934:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60934:2019 is applicable to mechanical switching devices designed as "circuit‑breakers for equipment" (CBE) for household and similar applications. CBEs according to this document are intended to provide protection to circuits within electrical equipment including its components (e.g. motors, transformers, internal wiring). This document covers also CBEs applicable for protection of electrical equipment in case of undervoltage and/or overvoltage. This document also covers CBEs which are suitable for isolation. This fourth edition cancels and replaces the third edition published in 2000, Amendment 1:2007 and Amendment 2:2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) clarifications for type testing purposes.

IEC 62626-1:2023 is available as IEC 62626-1:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 62626-1:2023 applies to enclosed switches-disconnectors with rated voltages up to 1 000 V AC for repair and maintenance work or cleaning work in load circuits. Devices within the scope of this document are switch-disconnectors in accordance with IEC 60947-3 with specific additional requirements. Enclosed switch-disconnectors in this document are suitable for isolation in accordance with the IEC 60947 series and are not equipped with means for remote control or automatic switching to avoid unexpected or accidental start. These devices are not used for operational switching, for example quick start and stop, jogging. This second edition cancels and replaces the first edition published in 2014. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) update of this document based on IEC 60947-1:2020.

This document covers internal arc-fault control devices, hereinafter referred to as IACD, which are intended to: - detect internal arc-faults in low-voltage switchgear and controlgear assemblies, by processing (at a minimum) the optical effect of an internal arc-fault, and - operate mitigation device (either external or combined) in order to minimize the effects of the internal arc-fault (see Figure 1). For the purpose of this document the terms "light" or "optical" covers more than visible spectra. They may cover also, for example, infrared or ultraviolet electromagnetic radiations (see Annex D). For combined-type IACD, this document is considered in addition to the relevant product standard for internal arc-fault mitigation devices (IARD per IEC TS 63107:2020). Compliance to the relevant product standard is mandatory and cannot be claimed by testing to this document alone. NOTE 1 Low-voltage switchgear and controlgear assemblies are usually described by IEC 61439 series. [Figure 1] Therefore, this document covers the following: - internal arc-fault control device (stand-alone, multifunction or combined); - one or more associated sensor(s) used to detect optical effect of the internal arc-fault; - sensor(s), sensing another physical effect, to confirm the fault; - associated or combined mitigation device. An IACD is not intended to trigger under normal operation of low-voltage switchgear and controlgear (i.e. absence of internal arc-fault), including normal arcing associated with operation of disconnecting and switching devices. This document only covers the following methods: - optical detection of the light caused by an internal arc-fault; - optional confirmation of internal arc-fault by line current measurement. Many different conductive materials could be used in LV assemblies (e.g. steel, copper, aluminium). Nevertheless, tests specified in this document are deemed to represent the most critical and challenging conditions for arc-detection and cover all combinations of conductive materials. NOTE 2 Compared to other materials (e.g. steel, aluminium), copper leads to a lower optical radiation energy. The rated voltage of the assembly in which an IACD is installed does not exceed 1 000 V AC. Such devices are designed to be operated and maintained by skilled persons only. This document does not cover: - DC internal arc-fault detection and control; - overcurrent relays; - AFDD (arc-fault detection devices) as defined by IEC 62606; - guidance on installation within assemblies; NOTE 3 The integration of an IACD into an assembly is described in IEC TS 63107. - use with additional measures needed for installation and operation within explosive atmospheres. These are given in IEC 60079 series documents; - requirements for embedded software and firmware design rules; for this subject, the manufacturer is responsible for taking additional safety measures; NOTE 4 IEC TR 63201 describes rules for firmware and embedded software development preventing errors in software. - cybersecurity aspects; for this subject, the manufacturer is responsible for taking additional safety measures; NOTE 5 See IEC TS 63208. - mobile applications. NOTE 6 Even when addressing internal arc-fault mitigation devices, this document does not supersede any other relevant product standard (e.g. IEC 60947-2 or IEC 60947-9-1). NOTE 7 DC arcing fault phenomena are under consideration. Further investigation is needed to comprehend DC arcing phenomena and required sensing.
