Decription:
KSD301 Thermal Switch is a single pole, snap action, automatic reset circuit breaker of Aluminum Alloy cased, provides a compact profile, broad design flexibility and versatile mounting options. designed to protect wiring harnesses.
Test method:
Sample is connected to the fixture of the equipment,and placed into the test equipment (Hot current of air in the space of test should be equipped with a stirrer and temperature is controllable).A detect current about 10mA(no more then 100mA)is passed through the sample and a thermometer is placed junction to the sample to monitor the opening temperature .The temperature of the test equipment is raised at the rate of 0.5～1℃ per minute until the sample functioned.
Working Principle of KSD301 Series Temperature Thermostat: When the electrical appliance works normally, the bimetallic sheet is in the free state and the contact is in the closed / open state. When the temperature reaches the operating temperature, the contact is opened / closed, and the circuit is cut / closed, so as to control the temperature. When the electric appliance cools to the reset temperature, the contact will automatically close / open and return to the normal working state.

Precautions:
1. When using the contact temperature-sensing installation, the metal cover should be close to the installation surface of the controlled appliance. To ensure the temperature-sensing effect, the temperature-sensing surface should be coated with thermal grease or other heat-conducting medium with similar performance.
2. Do not crush, loosen or deform the top of the cover during installation, so as not to affect performance.
3. Do not allow liquid to penetrate into the temperature controller, do not cause cracks in the shell, and do not change the shape of the external terminals at will.
4. The product is used in a circuit with a current of no more than 5A, and the copper core cross-section is 0.5-1㎜2 wire connection; when used in a circuit with a current of no more than 10A, the copper core cross-section is 0.75-1.5㎜2 wire. connect.
5. The product should be stored in a ventilated, clean, dry, and non-corrosive gas warehouse with a relative humidity of less than 90% and an ambient temperature of 40°C.
