In addition, we can customize a certain temperature if the quantity needed is big enough. To discuss about quotation and quantity case by case. Thermostats with Capillary 2 meters long are also available. Stock quantity limited. Click the link of picture below for details. 2. Product Compliance The product has been tested and conforms to relevant requirements of UL, TUV, RoHS and KC. 3. Specification and Drawing Each model bears the same dimensions except the length of bulb. Two lengths of bulb: - Thermostat with low temperature limit has long bulb 106±5mm. - Thermostat with high temperature limit has short bulb 60±5mm. Refer to table below. Size of installation hole on panel : Ф8mm L-Shaped Bracket Dimensions and Installation: Z-Shaped Bracket Dimensions and Installation: 4. Wiring Diagram and Manual Reset Switch Type in the thermostat is SPST (Single Pole Single Throw). That means it only has one input terminal "C" and only one output terminal "1", and serves as on-off switch in the circuit. Refer to the wiring diagram below. Electrical Rating: AC 250V/20A Recommended Connector: FDD2-250 (6.3mm). Wire Core 1.5~2.5mm². When the temperature rises and reaches the limit, the circuit break (switch OFF). To close the circuit again, remove the red cap and press the button once. To maintain good accuracy of the thermostat, the bulb shall be completely inserted into the liquid (water, oil, etc.) to be detected, as demonstrated in the diagram below. Attention: The body of thermostat is not water-proof, please keep it away from liquid. If the bulb can also be used to detect the temperature of gas or air, please anticipate lower accuracy as the temperature distribution in gas or air may not be so even as that in liquid. 5. Application Fields Application for the temperature protection of liquid heater, water boiler, oven, air heater, bakery machine, drier, kitchen appliances, etc. 6. Mechanism of Bulb and Capillary Thermostat Bulb and capillary thermostat has a fluid filled bulb and responds quickly to change of temperature. When temperature rises, the fluid inside the bulb expands via the capillary tube to an expandable diaphragm or bellow to open or close the electrical contact. Bulb and capillary thermostats provides the flexibility to place the sensor in remote place that can be very hot. 7.
