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.
