Predmet normy: | 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 (all parts)); - software and firmware requirements; NOTE 1 Guidance on embedded software is given in IEC TR 63201. - cyber security aspects (see IEC TS 63208). |
