Description
General information：
PTC thermistors acc. to DIN 44081 (triple sensors acc. to DIN44082) are used to protect electrical machines against thermaloverload.Thermistors have an even steeper R/T characteristic asthat defined in the DIN standard. The temperature range is from 70°C to 160°C. PTC thermistor beads with different rated responsetemp eratures can be connected in series. This permits an optimal and economic thermal protection of machines and windings with different limit temperatures.
Structure :
PTC Triple Thermistors (Standard Size)
PTC Identification and Part Numbers:
The color of the connection leads indenfies the rated response temperature. These are defined in DIN 44081/082.
