Low-voltage switchgear and controlgear - Part 7-4: Ancillary equipment - PCB terminal blocks for copper conductors
This part of IEC 60947-7 specifies requirements for PCB terminal blocks primarily intended for industrial or similar use. Mounting and fixing on the printed circuit board is made by soldering, press-in or equivalent methods to provide electrical and mechanical connection between copper conductors and the printed circuit board. This document applies to PCB terminal blocks intended to connect copper conductors, with or without special preparation, having a cross-section between 0,08 mm2 and 300 mm2 (AWG 28-600 kcmil), intended to be used in circuits of a rated voltage not exceeding 1 000 V AC up to 1 000 Hz or 1 500 V DC. NOTE 1 Large-cross-section terminal blocks are dedicated to the specific design of high-current PCBs. The range up to 300 mm2 is kept to cover any possible application. Examples of high current PCBs and PCB terminal blocks are shown in Annex C. NOTE 2 AWG is the abbreviation of “American Wire Gage” (Gage (US) = Gauge (UK)). 1 kcmil = 1 000 cmil; 1 cmil = 1 circular mil = surface of a circle having a diameter of 1 mil; 1 mil = 1/1 000 inch. This document can be used as a guide for special types of PCB terminal blocks with components, such as disconnect units, integrated cartridge fuse-links and the like or with other dimensions of conductors. If applicable, in this document the term “clamping unit” is used instead of “terminal”. This is taken into account in the case of references to IEC 60947-1.

Ferrite cores - Guidelines on dimensions and the limits of surface irregularities - Part 4: RM-cores
IEC 63093-4:2019 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of RM-cores and low-profile RM-cores made of ferrite, and the locations of their terminal pins on a 2,54 mm printed wiring grid in relation to the base outlines of the cores. It also gives guidance on allowable limits of surface irregularities applicable to RM-cores in accordance with the relevant generic specification. The selection of core sizes for this document is based on the philosophy of including those sizes which are industrial standards, either by inclusion in a national standard, or by broad-based use in industry. This document is a specification useful in the negotiations between ferrite core manufacturers and customers about surface irregularities. This first edition cancels and replaces the first edition of IEC 62317-4 published in 2005 and the second edition of IEC 60424-2 published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 62317-4:2005 and IEC 60424-2:2015: a) IEC 63093-4 integrates the contents of IEC 62317-4:2005 and IEC 60424-2:2015; b) IEC 60424-2:2015, Table 2, has been included in Annex C as Table C.1.

This part of IEC 61439 lays down the general definitions and service conditions, construction requirements, technical characteristics and verification requirements for low-voltage switchgear and controlgear assemblies. NOTE Throughout this document, the term assembly (see 3.1.1) is used for a low-voltage switchgear and controlgear assembly. This document cannot be used alone to specify an assembly or used for the purpose of determining conformity. Assemblies comply with the relevant part of the IEC 61439 series, Part 2 onwards. For assemblies not covered by Part 3 onward, Part 2 applies. This standard applies to low-voltage switchgear and controlgear assemblies only when required by the relevant assembly standard as follows: – Assemblies for which the rated voltage does not exceed 1 000 V in the case of AC or 1 500 V in the case of DC; – Assemblies designed for a nominal frequency of the incoming supply or supplies not exceeding 1 000 Hz; – Assemblies intended for indoor and outdoor applications; – stationary or movable assemblies with or without an enclosure; – Assemblies intended for use in connection with the generation, transmission, distribution and conversion of electric energy, and for the control of electrical energy consuming equipment. This document does not apply to individual devices and self-contained components such as motor starters, fuse switches, power electronic converter systems and equipment (PECS), switch mode power supplies (SMPS), uninterruptable power supplies (UPS), basic drive modules (BDM), complete drive modules (CDM), adjustable speed power drives systems (PDS), and other electronic equipment which comply with their relevant product standards. This document describes the integration of devices and self-contained components into an assembly or into an empty enclosure forming an assembly. For some applications, such as electrical equipment of machines or those involving, for example, explosive atmospheres, functional safety, there may be a need to comply with the requirements of other standards or legislation in addition to those specified in the IEC 61439 461 series.

Low-voltage switchgear and controlgear - Part 5-8: Control circuit devices and switching elements - Three-position enabling switches
This part of IEC 60947 series specifies requirements for three-position enabling switches. These switches are used as components of enabling devices to provide signals that, a) when activated, allow machine operation to be initiated by a separate start control, and b) when de-activated, − initiate a stop function, and − prevent initiation of machine operation. NOTE 1 The enabling control function is described in 9.2.3.9 of IEC 60204-1:2016 but the application of three-position enabling switches is not limited to a component of the enabling device described in IEC 60204-1. NOTE 2 This document does not deal with enabling devices. These switches are intended to be connected to circuits which rated voltage does not exceed 250 V AC 50 Hz/60 Hz or 300 V DC. EXAMPLE Devices incorporating three-position enabling switches are: - push-button enabling devices; - grip actuated enabling devices; - foot actuated enabling devices. See Annex A for more typical examples. This document does not apply to: − three-position enabling switches for non-electrical control circuits, for example hydraulic, pneumatic; − enabling switches without three-position mechanism; − emergency stop devices (see IEC 60947-5-5).
