250V 10A Temperature Controller Thermostat KSD301 KSD302 KSD303

The KSD series thermostat operates on the principle of bimetal discs that snap into action when sensing temperature changes. This snap action activates the contacts through the internal structure, ultimately controlling the circuit on/off function. Key features include fixed working temperature, reliable snap action, minimal flashover, extended service life, and reduced radio interference.

Manual Reset Type: Temperature sensing components consist of bimetallic strip. When temperature reaches the action range, it snaps quickly and the movable disc disconnects. The contact point cannot reset automatically when temperature declines; it requires manual reset by pushing the reset button to reconnect the circuit.

Auto Reset Type: Temperature sensing components consist of bimetallic strip. When temperature reaches the action range, it snaps quickly and the movable disc disconnects. The contact point automatically resets and starts working when temperature declines to the fixed reset point.

• Manual reset thermostats can reset when temperature declines 20°C after snap action by pressing the reset button
• Recommended reset force: 4-6 N (avoid excessive strength)
• For normal function, distance between reset button and close cover should not be less than 20.4mm

Used as temperature control for household electric appliances including coffee pots, automatic toasters, laminators, electric water pots, steam guns, steam irons, wind warmers, microwave ovens, water dispensers, and more.
