Inquiry (采购产品): PTC Thermistor Identification Lloyd Electric is an electric motor repair facility. We had a Siemens Electric motor in our shop for repair. This motor was installed on an Atlas-Copco air compressor and was running on a variable frequency drive. The thermistor was connected to terminals on the drive. We sent an inquiry to Siemens but haven't received a response. The resistance of the thermistor was 615 ohms at room temperature, 68 degrees F. The color of the lead wires are yellow and violet or yellow and blue. Any help to identify this device will be appreciated. **** Hidden Message ***** Gary Crawford 24013 Company: Lloyd Electric Co.
