专家解读视频
This part of IEC 60947 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. This consolidated version consists of the first edition (2003) and its amendment 1 (2006). Therefore, no need to order amendment in addition to this publication.
