Defrosting thermostats Automatic Reset SPDT In this configuration, the switch can be built to either open or close its electrical contacts on temperature rise.
Once thetemperature in the application has returned to the specified reset temperature, the contacts will automatically return to their original state.Typical uses of this construction include limiting and regulating temperatures in air conditioners,heat pumps and fan coil units
Automatic Reset SPDT This design is the same as the SPST described above with the addition of an auxiliary contact which makes circuit upon opening of the main contacts and breaks circuit when the main contacts reset. Refer to the General Electrical Ratings chart for rating limitations on the auxiliary contacts. Typical uses of this construction include fan speed changeover at a specified temperature and lighting of an indicator lamp when an abnormal temperature conditionhas been reached.
Main technical specification:
*Action characteristic: Single cutter,single throw (SPDT),
*Electric rating : 250VAC@16A/250VAC@25A
*Insulation resistance : ≥100MΩ 500VDC
*Action temperature range : -30℃～90℃
*Lead wire and temperature can be decided to Users requirements.
*Controls are 100% operation checked and dielectric tested.
