GB/T 14048.16-2006 Low-voltage switchgear and controlgear Part 8: Control units for buile-in thermal protection (PTC) for rotating electrical machines (English Version)
This Part specifies the rules and industrial application of control units that respond to thermal detectors integrated with rotating electrical machines and perform switching functions in accordance with GB/T 13002-1991. For systems containing positive temperature coefficient (PTC) thermistor detectors with special characteristics, this standard specifies the rules for this type of system and its associated control units. The PT100 detector complies with IEC 60751-1983, which specifies the resistance value corresponding to the temperature of the detector. This section lists the coordination characteristic requirements when this particular PTC thermistor detector and its associated control unit (labeled "Type A detector" and "Type A control unit") are used in a thermal protection system.
