| Application Field: |
| PTC thermistors are used to monitor temperature in machines and installations. The design ensures short response times and easy installation. |
| The Product Sells Point： |
| PTC thermistors acc. To DIN 44081(triple sensors acc. To DIN 44082) are used to protect electrical machines against thermal overload. Thermistors have an even steeper R/T characteristic as that defined in the DIN standard. The temperature range is from 60 to 180℃. PTC thermistors beads with different rated response temperatures can be connected in series. This permits an optimal and economic thermal protection of machines and windings with different limit tempratures. |
