PTC Thermistors For Electric Motor Protection(Single Thermistor)

$170.00

Key Benefits:
PTC thermistors are used to monitor temperature in machinesand installations.The design ensures short response times andeasy installation.

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 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.
