KSD-75 is Thermal Protector. A thermal protector, also known as a thermal cutoff or thermal fuse, is a safety device designed to prevent overheating of electrical appliances, components, or systems. It works by interrupting the electrical circuit when a certain temperature threshold is reached, thereby preventing potential fires, damage, or other hazards caused by excessive heat.

Thermal protectors are commonly used in various applications, including:

1. Motors: Thermal protectors are often embedded within motors to prevent them from overheating and causing damage or fire risks. They are found in appliances like refrigerators, air conditioners, fans, and more.

2. Electrical Transformers: Transformers can generate a significant amount of heat during operation. Thermal protectors ensure that they don’t exceed safe operating temperatures.

3. Power Supplies: Electronic devices like power supplies can also be protected from overheating using thermal protectors.

4. Industrial Equipment: Various industrial equipment and machinery that generate heat during operation can be equipped with thermal protectors for safety.

KSD-9700 is Thermal Protector. A thermal protector, also known as a thermal cutoff or thermal fuse, is a safety device used in various electronic and electrical applications to prevent overheating and potential fire hazards. It is designed to interrupt the current flow when a specific temperature is reached, thereby protecting the equipment and surrounding environment from damage.

Features or structure :

KSD-9700 series thermal protector consists of dish shape high sensitive bimetallic elemeng,movable contact-head,static contact-piece,soleplate,outer case,ghermal resistant lead and so on.When operation,the bimetallic element is in free state and movable contact-head and static contace-piece are closed and the circuit is on.When the electric appliance is in operation is in operation and produces heat caused by some troubles and temperature is raised to the rated action temperature of the product,the bimetallic element produces inner stuess and acts quickly and pushes the movable contact-head and make the vontact point off and the power supply is rurned off the electric appliance stop.in this way the thermal protection is made.When the temperature of electric appliance to be protected is dropped to the rated reset temperature.The bimetallic element restores to its primary state and contact point is closed .The electric appliance restores its work.The product has many advantages such as small in resistor,puick in temperature feeling,fast in action.Safe and reliable.compact and so on. Switch Material:Metal or Plastic The metals outer shell type the product outer shell take an electricity, should add to insulate a coat.  […]
