Bimetal Thermal Switches

Our range of Bimetal Thermal Switches are specially designed for heatings, lightings and motors. It is focused on the low temperature range. Based on the principle of bimetal heat expansion and cold contraction, the thermal switch can control the temperature of application under a very small range.
* Special Features of Bimetal Thermal Switches:
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 0-50A C available.
8. MAX TEMPERATURE 180A C available

* Electrical Ratings:
1. 20A / 120V AC
2. 10A/ 230V AC

* Temperature Ratings:
1. Off temperature: 0-180A C
2. Tolerance:A 5A C
3. ON temperature: 5A C for creeping action;
20A C for snap action

* Special notes for thermal switch:
1. The temperature rising speed under calibration should be less than 1A C 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 70A C
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.
