SIST-TP IEC TR 61439-0:2023(Main)
Low-voltage switchgear and controlgear assemblies- Part 0: Guidance to specifying assemblies
IEC TR 61439-0:2022

IEC TR 61439-0:2022 standards for low-voltage switchgear and controlgear assemblies, there are system and application details that are specified by the specifier to enable the manufacturer to produce an assembly that meets the needs and expectations of the specifier.
IEC/TR 61439-0:2022, identifies from the specifier’s perspective those functions and characteristics that are defined when specifying assemblies. It provides:
an explanation of the assembly characteristics and options within the IEC 61439 series;
a guidance on how to select the appropriate options and define characteristics so as to meet specific application needs; and
an assistance in the specification of assemblies.  References within this document to the interface characteristics of an assembly and the requirements with which they will comply assume that the assembly is designed, manufactured, and verified in accordance with the relevant part of the IEC 61439 series.
This third edition cancels and replaces the second edition published in 2013. It constitutes a technical revision.
This third edition includes the following significant technical changes with respect to the previous edition:  
alignment with IEC 61439-1:2020;
addition of new content in Clause 13 regarding current ratings;
addition of a new subclause 12.8.1 detailing the fundamentals of the forms of internal separation;
alignment of Annex B with Annex AA of 61439-2:2020;
removal of the annexes detailing items subject to agreement between specifier and manufacturer for all product parts as not all of them can always be up to date

Low-voltage switchgear and controlgear - Part 8: Control units for built-in thermal protection (PTC) for rotating electrical machines (IEC 60947-8:2021)
EN IEC 60947-8:2023

This part of IEC 60947 series specifies requirements for control units, which control a switching device in response to the PTC thermistors incorporated in rotating electrical machines and the industrial application.
It specifies requirements for that type of system comprising a positive temperature coefficient (PTC) thermistor having particular characteristics, and its associated control unit.
This document includes:
- the characteristics, construction, performance and tests of the control unit; and
- its association with a PTC thermistor designated "Mark A".
This document does not cover:
- the incorporation of thermal protections into rotating machines and their maximum winding temperature. See IEC 60034-11;
- use of the product within explosive atmospheres (see IEC 60079 series);
- software and firmware requirements;
NOTE 1 Guidance on embedded software is given in IEC TR 63201.
- cyber security aspects (see IEC TS 63208).
NOTE 2 It is not possible to specify all the requirements for the operating characteristics of a control unit, as they are dependent on some aspects of the PTC thermistors. Some aspects of the requirements of the thermal protector system can only be specified when account is taken of the characteristics of the rotating machine to be protected and the method of installation of the PTC thermistor within the machine.

Low-voltage switchgear and controlgear - Part 5-2: Control circuit devices and switching elements - Proximity switches
EN IEC 60947-5-2:2020/A11:2022

EN-IEC 60947-5-2 applies to inductive and capacitive proximity switches that sense the presence of metallic and/or non-metallic objects, ultrasonic proximity switches that sense the presence of sound reflecting objects, photoelectric proximity switches that sense the presence of objects and non-mechanical magnetic proximity switches that sense the presence of objects with a magnetic field. Products covered by the scope of this document are not subjected to defined behaviours under fault conditions. Proximity switches with defined behaviour are covered by IEC 60947-5-3 and have to fulfil additional requirements. These proximity switches are self-contained, have semiconductor switching element(s) and are intended to be connected to circuits, the rated voltage of which does not exceed 250 V 50 Hz/60 Hz AC RMS or 300 V DC. Examples of typical applications for in-scope products: - factory automation and machinery industry; - logistic and packaging industry; - conveyor belts, lifts; - process industry; - power plants. Special applications (e.g. corrosive atmosphere) can cause additional requirements. This document is not intended to cover proximity switches with analogue outputs. The object of this document is to state for proximity switches: - definitions; - classification; - characteristics; - product information; - normal service, mounting and transport conditions; - constructional and performance requirements; - tests to verify rated characteristics. Products covered by the scope of this document are expected to be selected, installed, and maintained by skilled personnel only.
