KSD Series Bimetal Disc Thermostat Normally Closed HC301 Thermal Cutoff Switch for Electric Griddle, Bread Maker

The KSD301 ceramic automatic reset thermostat is the core safety component for overheating protection in bread makers, directly embedded into the heating chamber or the surface of the metal heating element. When the baking temperature exceeds the preset value (e.g., 180–220°C), the bimetallic strip instantly switches off the circuit; once the temperature drops below the safety threshold (15–30°C below the action value), it automatically resets and restores power, ensuring the safety and efficiency of continuous baking without any manual intervention.

Product feature:

1. Durable ceramic shell
300°C high temperature with zero deformation: The operating temperature of a bread maker is typically ≤220°C. The ceramic shell poses no risk of melting and has a lifespan 200% longer than plastic.

Resistant to water vapor corrosion: The sealed ceramic structure withstands steam from dough fermentation, preventing metal components from rusting and malfunctioning.

2. Precise temperature control ensures baking quality
±5°C action accuracy: Strictly controls the critical point for bread browning (e.g., 200±5°C), preventing burning or undercooking.

3-second rapid response: Tight installation + thermal grease ensures minimal temperature sensing delay, instantly cutting off overheating risks.

3. 10,000-cycle lifespan precisely matches requirements
Scientific lifespan design: Based on an average of 3 baking cycles per day, the 10,000-cycle lifespan supports over 9 years of use (redundant design accounts for actual fluctuations).

Enhanced contact point process: Silver alloy contact points reduce arc loss, ensuring contact resistance ≤50mΩ after 10,000 cycles (national standard requirement: ≤100mΩ).

4. Automatic reset for convenience and efficiency
Smart baking continuation: Automatically powers on when temperature drops, enabling unattended multi-stage baking (e.g., fermentation → baking →保温).

Customizable reset temperature difference: Supports a reset range of 15–30°C (20°C recommended for bread makers), preventing frequent power cycling that could damage the device.
