Product Usage:

It is widely used in the dual protection of fractional horsepower motors, electric heating appliances, fluorescent lamp ballasts, transformers, automobile motors, integrated circuits and general electrical equipment from overheating and overcurrent.

Tensile strength test: The lead end of the product should be able to withstand a tensile force greater than or equal to 20N. The wire will not break or slip out.

Product performance

*Insulation voltage:

a The product should be able to withstand AC660V for 1min without breakdown and flashover between the leads when disconnected

b. The product lead and the insulating shell can withstand AC1800V for 1S without breakdown and flashover;

Insulation resistance: Under normal conditions, the insulation resistance between the lead and the insulating shell is above 100MΩ. (The meter used is a DC500V megohmmeter)

*Contact resistance: The contact resistance of the product should not be greater than 50mΩ.

*High temperature resistance test: The product is placed in an air environment 50°C higher than the rated operating temperature for 96h.

*Low temperature resistance test: The product is placed in an air environment of -40°C for 96h.

*Vibration resistance test: The thermal protector should be able to withstand amplitude 1.5mm, frequency change 10~55Hz, scanning change cycle 3~5 times/min, vibration direction X, Y, Z, continuous vibration in each direction for 2h.

*Drop test: The product falls freely from a height of 0.7m once.

*Compression test: the product should be able to withstand 100N static pressure for 1min

Product life

When the product is under the conditions of rated voltage, current, and power factor of 0.7, the external heating source can make it operate 10,000 times and should meet the following conditions:

a The disconnection temperature change should be within ±5℃ of the initial value;

b The contact resistance should be below 100mΩ;

Other Matters:

The heating rate of the disconnection temperature detection should be controlled to 1℃/1min;

The product cannot withstand strong impact and pressure during use;
