Y Series 250V 2A 3A 145℃ Thermal Cutoff Fuses composed of ceramic shell

Electric Fan Motor Axial Ceramic Case Resistor Type Temperature Fuse Thermal Cutoff Fuse

Structure
The thermal fuse is composed of ceramic shell, low melting point alloy wire, special resin, pin copper wire and sealing resin.

Apprearance
The marking must be clear; the sealing resin should fill the mouth and it is acceptable; the lead tin-plated layer is good; there is no oxidized black spot damage; the shell has no damage marks, perforations, etc.

Experimental Method
The experimental conditions are temperature 25±10℃, humidity 65±15%M
1 Action humidity accuracy: Rely on the IE691: 1995 inspection method and measure with the built-in silicone oil pool in the thermostat.
2 Size: Measure the finished product with a micrometer/vernier ruler.
3 Appearance: visual inspection.
4 Insulation resistance: Measure the finished product with SP-3A digital megohmmeter, and measure the voltage DC500V.
5 Withstand voltage: Use the ZNY-12 withstand voltage test to determine the finished product, which takes 1 minute.
6 Tensile force: Measure the finished product with a push-pull tester, and the pin bears 1.5 pounds of pulling force for 10 minutes without damaging the components.
7 Torsion: Bend the lead at 10mm at 90°C, and then reverse it at 180°C without damaging the component.

Test Requirements
1. Rated operating temperature (Tf): The temperature at which the thermal fuse is tested according to the standard method to change its conductive state. (The Japanese Electrical Appliances Management Law stipulates that the tolerance range is ±7℃ for operation).

2. Measured operating temperature: The temperature fuse is heated in the silicone oil bath at a rate of 0.5-1°C per minute, and the fusing temperature obtained when the detection current is less than 100MA. It is the actual temperature of the thermal fuse.

3. Holding temperature (Tc): The maximum temperature at which the thermal fuse can maintain 168 hours without changing its conductive state when passing the rated current.

4. Limit temperature (Tm): The maximum temperature at which the thermal fuse can withstand 10 minutes without reconnection.

5. Rated voltage (Ur): The highest working voltage of the thermal fuse.
