Specifies rules for control units, which perform the switching functions in response to the thermal detectors incorporated in rotating electrical machines according to IEC 60034-11, and the industrial application. It specifies rules for that type of system comprising a positive temperature coefficient (PTC) thermistor detector having particular characteristics, and its associated control unit. The PT100 detectors are covered by IEC 60751, where the resistor values are given according to the temperatures of the detector. The present rules lay down the characteristics of association of this particular positive temperature coefficient thermistor detector and its associated control unit (designated "Mark A detector"" and "Mark A control unit""), when they are used in thermal protection systems. NOTE 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 thermal detectors. 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 detector within the machine. For these reasons, for each characteristic it is necessary to specify who is responsible for stating the required values and who is responsible for compliance with the requirement and for carrying out any confirmatory test.

IEC 62026-3:2014 specifies an interface system between single or multiple controllers, and control circuit devices or switching elements. The interface system uses two conductor pairs within one cable - one of these pairs provides a differential communication medium and the other pair provides power to the devices. This part establishes requirements for the interoperability of components with such interfaces. This third edition of IEC 62026-3 cancels and replaces the second edition published in 2008. This third edition constitutes a technical revision. The main changes with respect to the previous edition are the followings: - specification of group 4 messages (5.1.2); - clarifications on messaging protocol (5.2); - addition of I/O multicast poll messages (5.5.2 and 5.5.8); - clarifications on slave behaviour (5.5.4 and 5.5.9); - clarifications on physical layer (transceiver) in 5.7; - miscellaneous corrections/clarifications on cable (8.2); - clarifications on EMC testing (9.2.10) and logical testing (9.3).

IEC 62683:2013 is used to facilitate the exchange in electronic format of data describing low voltage switchgear and controlgear. This standard provides clear and unambiguous definitions of a limited number of properties and classes which are mainly used for presentation, selection and identification of products particularly in electronic catalogues. Each property has an unambiguously defined meaning and naming, and where relevant, a defined value list, a defined format and a defined unit. The intention is to produce a reference dictionary which allows a general description of low voltage switchgear and controlgear classes based on the defined properties. The intention is not to cover manufacturer specific features.
