The KSD 9700 thermal protector enhances safety in heating elements by preventing overheating and ensuring controlled operation. Here's how it works and contributes to safety:
The KSD 9700 is installed near or directly on the heating element to monitor its temperature.
It detects excessive heat buildup caused by factors like prolonged use, high ambient temperatures, or electrical malfunctions.
Bimetallic Disc Activation:
When the heating element's temperature exceeds the preset threshold (e.g., 100°C or 150°C), the bimetallic disc inside the protector bends.
This movement activates the switch to:
Open the Circuit (NC Type): Stops power flow to the heating element, preventing further heat buildup.
Close the Circuit (NO Type): Triggers an auxiliary system like a cooling fan or an alarm.
Overheating in heating elements can lead to fires if not controlled.
By cutting off power when unsafe temperatures are detected, the KSD 9700 eliminates the risk of ignition.
Heating elements, wiring, and surrounding materials are shielded from damage caused by excessive heat, extending the lifespan of the appliance.
For auto-reset models, the thermal protector restores the connection once the element cools to a safe temperature, ensuring the device operates normally without manual intervention.
Manual reset models add an extra layer of safety by requiring user inspection before reactivation.
Space Heaters: Prevents overheating due to blocked vents or prolonged use.
Electric Blankets: Ensures the surface temperature stays within a safe range.
Hot Plates and Toasters: Prevents thermal runaway during cooking.
