The SSM PTC thermistor from Thermik Corporation is designed for temperature monitoring applications, particularly suitable for installation in the windings of electric motors and transformers. It features a response temperature range from 60 ¬8C to 190 ¬8C, with resistance values that significantly increase at the rated response temperature, allowing for effective load current circuit shutdown via a trigger device. The thermistor is constructed with a Mylar¬Æ-Nomex¬Æ insulation cap, providing mechanical stability and minimizing cold flow. It achieves response times of 5 to 10 seconds, depending on the version. The device operates within a voltage range of 2.5 V DC to 24 V DC, with a maximum permissible operating voltage of 30 V DC and a high voltage resistance of 2.5 kV. Customizable options are available, including variations in cable insulation material, cable cross-section, and connection technology. The SSM thermistor complies with DIN VDE 0898-1-401:2016 and IEC 60034-11:2004 standards, ensuring reliability in temperature-sensitive applications.
Where possible, the PTCs are to be inserted parallel to the coil. As a result, when shaping the coil ends, the mechanical stress of the PTCs is minimised. In so doing, the Mylar®-Nomex® shrink cap is highly suited to this purpose due to its mechanical stability (no cold flow in contrast to Teflon®). In connection with the miniature pill (Ø 1.5 mm) response times of 5 to 10 seconds (max.) are achieved depending on the version.
Thermik thermistors correspond to DIN 44081 and/or 44082, IEC 60034-11-2 and are characterised by high resistance to temperatures. Resistance increases greatly in the range of the rated response temperature. Via a trigger device, this change can be used to shut down the load current circuit. Electronic evaluations in are also possible in different applications.
