MZ6 type motor protection PTC thermistor
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 thermistor beads with different rated response temperatures can be connected in series. This permits an optimal and economic thermal protection of machines and windings with difference limit temperatures.
