Product Description

Product Description

CQC Certified Automatic Reset 250V 10A Bakelite KSD301 Thermostat for Hair Dryer

The KSD301 Bakelite Snap Action Thermostat is an "automatic temperature switch" with a bakelite base and a bimetallic strip as its core. 

Its core function is to "break off when the temperature reaches the set point and reset to conduction when the temperature drops," ensuring constant temperature operation of equipment while preventing overheating damage.

Key Features (Crucial Advantages for Suitable Applications):
1) Passive Operation: No external power supply required; relies on the thermal expansion and contraction of the bimetallic strip for operation, resulting in a simple structure and low cost.
2) High Temperature Resistance + Excellent Insulation: The bakelite base can withstand temperatures ≥180℃, resisting the instantaneous high temperatures when the contacts break, preventing short circuits.
3) Precise Action: Standard operating temperature range 20℃~180℃, accuracy ±3℃~±5℃ (customizable ±2℃ high precision).
4) Long Lifespan: Snap-action reduces contact wear; temperature cycle life ≥10,000 cycles, suitable for mass production equipment.

Operating Temperature & Reset Temperature: 

The Reset Temperature of the KSD301 bakelite snap-action thermostat is not a fixed value; it varies with the corresponding Operating Temperature.

The industry standard tolerance is typically ±5℃.

Furthermore, the temperature difference between reset and operation can be customized.

Common specifications and their corresponding reset temperatures are as follows:

Operating Temp.	Reset Temp.	Operating Temp.	Reset Temp.	Operating Temp.	Reset Temp.	Operating Temp.	Reset Temp.
30℃	≥15℃	75℃	60±5℃	125℃	110±5℃	190℃	175±5℃
35℃	20±5℃	80℃	65±5℃	130℃	115±5℃	200℃	185±5℃
40℃	25±5℃	85℃	70±5℃	135℃	120±5℃	205℃	190±5℃
