Temperature Protection Aupo Thermal Fuse Cutoff TF 125℃ 250V 3A A3-3A-F Plastic Case Thermal Links For Home Appliances

 

 

Description

 

The following product specifications apply to fuses of the A series. The A series consists of thermal cutoff fuses for over-temperature protection. The A series thermal fuses are widely used in various applications such as transformers, adapters, secondary batteries, household appliances, gas water heaters, lighting and other heating equipment.

 

The A-3A-F thermal cutoff fuses are non-resetting single-pole and normally closed devices and provide accurate, reliable protection for high temperature applications against overheating through interrupting electric current. With their metal body and strong leads these fuses offer a sturdy built and high rated currents such as 3 Ampere.

Ratings Indicator Description
Rated Functioning Temperature Tf The temperature at which the thermal cutoff fuse changes its state of conductivity and opens the circuit with detection current of <10mA as the only load. The temperature tolerance for UL CSA and VDE standards is +0. -10ºC
Hold Temperature Th The maximum temperature at which a thermal cutoff can be maintained while conducting rated current for 168 hours without causing a change in the conductivity to open the circuit.
Maximum Temperature Limit Tm At the rated voltage, the temperature the fuse can withstand for 10 minutes at highest temperature rating without change in the conductivity
Rated Current Ir The maximum current which the thermal cutoff fuse is able to carry and not affect its electrical characteristics.
Rated Voltage Ur The maximum voltage which the thermal cutoff fuse is able to carry and not affect its electrical characteristics.

 

 

Test Conditions

 

1 Insulation Resistance

 

A .Lead and shell For the thermal fuse body in testing the insulation resistance between wire and plastic shell, should be the first resistance limit pointer adjustment for the position of the 2 m Ω, then use the foil package thermal fuse body shell, then measure the insulation resistance between wire and metal foil.When indicating value of the insulation resistance is greater than 2 m Ω;NG signals does not produce, found the sample is qualified.

 

B. (after disconnecting) between the two lead On heat fusing two fuses, in testing the insulation resistance between the resistance limit pointer adjustment to the first position in the 0.2 M Ω, then measure the heat fusing the insulation resistance between the two leads.When indicating value of the insulation resistance is greater than 0.2 M Ω;NG signals does not produce, found the sample is qualified.Lead and shell For the thermal fuse body in testing the insulation resistance between wire and plastic shell, should be the first resistance limit pointer adjustment for the position of the 2 m Ω, then use the foil package thermal fuse body shell, then measure the insulation resistance between wire and metal foil.When indicating value of the insulation resistance is greater than 2 m Ω;NG signals does not produce, found the sample is qualified.

 

 

2 Dielectric strength

 

A. fuses with the shell On the thermal fuse body between the wire and plastic shell to wear strength test, the fuse body shell with metal foil, and then between the wire and metal foil test voltage of 1500 v (AC), a minute, if you do not see any discharge or breakdown phenomenon is found for qualified. B. (after disconnecting) between the two lead On the thermal fuse body fight between two fuses in strength test, applying test voltage of 500 v (AC) between the two leads, a minute, if you do not see any discharge or breakdown phenomenon is found for qualified.
