The KSD301 thermostat is commonly used in electric heaters for temperature control and protection. Here's how it works:
Temperature Sensing: The KSD301 is a snap-action thermostat, meaning it responds to a specific temperature threshold. It contains a bimetallic disc that reacts to temperature changes. When the temperature rises, the disc bends due to thermal expansion.
Contact Opening and Closing: The bending disc opens or closes the electrical contacts inside the thermostat. When the temperature exceeds the preset limit, the contacts open, cutting off the power to the electric heater. This prevents overheating and ensures safety.
Resetting: Once the temperature drops back down to a safe level, the disc returns to its original position, allowing the contacts to close again, and power is restored to the heater. This cycle repeats as necessary.
Safety Feature: The KSD301 provides automatic reset functionality, meaning it does not require manual intervention once the temperature returns to normal. This is particularly useful for appliances like electric heaters, where overheating can lead to damage or fire hazards.
The thermostat ensures that the electric heater operates within safe temperature limits, improving both performance and safety.
