USE

Control relay (230 V single phase) for warming up motor windings by PTC thermal sensor and ambient temperature control.
Can be plugged into 11 pole connection base.
- The relay remains on as long as the value of the measured input resistance ranges between 40 and 2500 ohms.
- Triggering of the relay above 2500 ohms and re-setting once the resistance value falls below 1500 ohms.
- Triggering of the relay below 40 ohms and re-setting above 50 ohms.
- The relay is triggered when ambient temperature is between 5 and 45 ºC (60 ºC if you bridge terminals 8 and 9).
