What Is Bi-metal Disc Thermostat?
KSD301 series temperature sensing element is a bimetal, is the most commonly used electrical overheating protection. When the electrical work, the bimetal is in a free state, the contacts are in the closed / disconnected state, when the temperature of the electrical appliance does not rise normally, when the protection action temperature of the Bi-metal Disc Thermostat is reached, subject to heat effects Bimetallic, produce internal stress and rapid action, open / close contact, off / turn-on circuit, which play a protective role in temperature. When the electrical cooling to the reset temperature, the contact automatically closed / open, turn on the power, to return to normal working condition. KSD301 series of products can generally be repeated tens of thousands of times.

Control Method
KSD series of temperature control after years of technology development, in order to adapt to the product of a variety of temperature control methods, in the Ya Xun, to meet the requirements of different customers, the development of a variety of temperature control products:
1. Otomatik sıfırlama: changes or decreases with temperature, the internal contact is automatically disconnected or automatically closed.
2. Manual reset (anti-dry type): Mainly used in water heaters, when the temperature rises, the contact will automatically disconnect; when the controller temperature cooling, you must manually press the button to reset the contact again closed power.
3. Normalde kapalı(NC): Electrical appliances work properly, the contact is closed, the thermostat is in power state, when the temperature reaches the operating temperature, the bimetallic sheet heat generated internal stress, and rapid action, open the contacts, cut off / on circuit, which play a role in temperature control.
4. Normalde açık tip(HAYIR): Electrical work, the contact is in the open state, the thermostat is in power state. Sıcaklık çalışma sıcaklığına ulaştığında, the bimetallic sheet heat generated internal stress, and rapid action, closed contact, connected to the cooling power supply, reducing the temperature of the heat generating element, which play a protective role.

2) 50A; 55A; 60A;
7. Defrost type: Mainly used in refrigerator defrost control. In the compressor running to a certain time, Immediately after the temperature of the -14 ° C felt by the defrosting thermostat on the evaporator, turn on current, at this time defrost timer operation, defrosting heater began to work, when the defrost thermostat feel +5 °C, the defrost thermostat contacts open, defrost thermostat (tube) to stop working.
