KSD301 Snap Action 250V 10A 16A Normal Closed Open Automatic Manual Reset Thermostat Bimetal Thermal Protector
KSD301 snap action thermostat is small-size bimetal thermostat series with a metal cap,which belongs to thermalrelays’family.The main principle is that one function of bimetal discs snap action under the change of sensing temperature.The snap action of disc can push the action of the contacts through the inside structure,then caused on of off of the circuit finally.The main characteristics are the fixation of working temperature,the reliable snap action,less flashover,longer working life and less radio interference.

The specification can also be manufactured as request.
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.
