Low-voltage switchgear and controlgear - Control units for built-in thermal protection (PTC) for rotating electrical machines

BS EN IEC 60947-8:2023 发布历史

1   Scope 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 ...
