Heating Thermostat Advantages
30A Current Rating
The AC 250V 30A rating allows this Heating Thermostat to handle higher-current heating circuits within its rated limits.
Wide Temperature Range
The 0–320°C range provides temperature control for cooking equipment and other high-temperature heating applications.
Adjustable On-Off Difference
The available 2–12°C on-off difference provides different switching gaps for equipment with different temperature control requirements.
Flexible Bulb and Capillary Configuration
The sensing bulb length follows the ordered temperature range. Capillary lengths from 300 mm to 2000 mm can be selected according to the distance between the sensing point and switch mounting position.
Mechanical Temperature Control
The WHD-105BA uses a liquid-filled sensing bulb, capillary tube, and mechanical switch. No electronic temperature control interface is required.
Heating Thermostat Applications
The WHD-105BA is used in heating equipment such as:
Deep fryers
Hot plates
Electric ovens
Griddles
Electric kettles
Thermal containers
Sealing machines
Other high-temperature heating equipment
The final application depends on the required temperature range, electrical load, installation conditions, and equipment design.

WHD-105BA Heating Thermostat FAQ
Can the Heating Thermostat switch a heating element directly?
The WHD-105BA is rated at AC 250V 30A. For a purely resistive load at 250V, this corresponds to a theoretical maximum of 7.5 kW. Actual switching capacity depends on the load type and operating conditions, so the load should remain within the specified rating.
What is the temperature range of the WHD-105BA?
The Heating Thermostat has a temperature range of 0–320°C.
What on-off temperature difference is available?
The available on-off temperature difference is 2–12°C, depending on the selected version.
How should I choose the capillary length?
Measure the distance between the sensing point and the switch mounting position, then allow additional length for routing. Available capillary lengths range from 300 mm to 2000 mm.
What information should I provide when ordering?
Please provide the required working temperature range, distance between the sensing point and switch mounting position, load voltage and current, and required on-off temperature difference.
Which on-off difference should I choose for the Heating Thermostat?
A narrower difference keeps the controlled temperature closer to the setting and results in more frequent switching. A wider difference reduces switching frequency but permits a larger temperature variation. The suitable version depends on the equipment's control requirements.
Can the WHD-105BA be customized?
Yes. Custom, OEM, and ODM requirements can be discussed for temperature range, capillary length, sensing bulb configuration, on-off difference, and other confirmed specifications.
Do you provide wholesale supply?
Yes. We provide Factory Supply of the Heating Thermostat for wholesale buyers, distributors, heating equipment manufacturers, and OEM projects.
