WAA2 creep action thermostat is specially designed for low voltage appliances temperature control,applicable to car seat,medical cushion and heating pad.It is focused on the low temperature range and small temperature differential.The thermostat can pre-set temperature,no need extra adjustment.The lead wire is optional and the case is live.Insulation sleeving might be needed.
* Special Features of thermal switch:
1. Temperature is 100% calibrated 2. Both Snap Action and creep action are possible 3. Type and length of wires are optional 4. Terminals can be same or opposite end 5.100% comply with RoHS 6.100, 000 life cycles 7. LOW TEMPERATURE SETTING 5-50 deg C available. 8. MAX TEMPERATURE 180 deg C available
* Electrical Ratings:
1.20A / 120V AC
2.10A/ 230V AC
* Temperature Ratings:
1. Off temperature: 5-180 C 2. Tolerance: +/-5 C 3. ON temperature: 5C for creeping action; 20C for snap action
* Special notes for thermal switch:
1. The temperature rising speed under calibration should be less than 1C per 2 minutes;
2. Vacuum varnishing is not applicable. Specially treated thermal switch is possible;
3. Varnishing under room temperature is possible. The temperature has to be less than 70C;
4. If the contact resistance is over 50m Ohm, please connect the thermal switch to the circuit of 60-100VAC, 2-5A and make the thermal switch to action 2 or 3 times. Then, test the contact resistance again. The resistance would be decreased.
* Applications of WAA2 thermal switch:
1. Motors, transformers and appliances 2. Pumps, Heating and lightings 3. Other applications which need low temperature control
