WAA2 Golden Plated Contacts Creep Action Bimetal Thermal Protector
WAA2 Golden Contacts Creep Action Thermal Protector Bimetal Thermostat
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
* Good conductive bimetal ensures that it can withstand certain current;
* Creep action, the contacts open and close slowly;
* Good temperature consistance, small temperature differential;
* Pre-set temperature, no need extra adjustment;
* Lead wire is optional and the case is live, insulation sleeving might be needed;
* Same or oppsite terminal directions optional;
* Wire riveting is customized.
Application
1. Blanket, Heating pad
2. Medical pads
3. Other applications which need low temperature control

Special Notes
1. The temperature rising speed under calibration should be less than 1°C per 2 minutes;
2. Vacuum varnishing is not applicable. Specially treated thermostat is possible;
3. Varnishing under room temperature is possible. The temperature has to be less than 70°C;
4. If the contact resistance is over 50m Ohm, please connect the thermostat to the circuit of 60-100VAC, 2-5A and make the thermostat to action 2 or 3 times. Then, test the contact resistance again. The resistance would be decreased.
