MZ6 type motor protection PTC thermistor

GENERAL INFORMAITON
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.
