Low-voltage switchgear and controlgear - Control units for built-in thermal protection (PTC) for rotating electrical machines has-hardcopy What is BS EN 60672-11 Scope 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 6003411, 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
