Ao littel-Aupo thermal cutoff fuse Introduction

 

AUPO thermal cutoff fuse was established in 1986 ,which is an advanced high-tech enterprise that specialized in thermal links (thermal protectors) research and development, production and sale. Developed more than 10 series 100 models of thermal links, and our annual productivity achieves 1 billion pieces. The AUPO strictly operates under superior management system and quality assurance system based on ISO9001. Also our products have been recognized and certificated by a number of domestic and foreign safety laboratories including UL, CUL, VDE, TUV, CSA, PSE, KTL-EK, CCC, and so on. Our own laboratory has been certified by UL and VDE as the witness laboratory.

Product Overview

 

The thermal cutoff fuse (TCO) are non resetting, thermally sensitive, single pole, normally closed devices and are intended to be used in various appliances.A temperature sensitive thermal cutoff fuse melts and opens electrical contacts when temperatures exceed the rating of the thermal fuse. Thermal cutoff fuse are providing protection against potentially hazardous overheating conditions in billions of products around the world.
Standard product offerings include:


Thermal Cutoff Fuse
* Metallic Case type (Axial, Spring Action, Current : 10A ,15A) 
* Low melting alloy type ( Axial, Surface tension type, Current : 2A, 5A) 


Note that the TCO shall be connected at the readily detectable location when abnormal conditions such as thermostat failure, fan failure, locked rotor, dry operation, etc.,might occurr in the appliance.


TCO is designed to lessen the heat created from TCO itself, but there may be a difference between the
ambient temperature and operating temperature of TCO due to wrong connection method.


In order to minimize the difference between ambient temperature and operating temperature of TCO, it is recommended that the creation of heat can be minimized around the TCO connected area under normal
operating condition, but the heat generation can be maximized at TCO connected area under abnormal condition.

Application

 

Motor Protection Limitor Non-Resettable TF 172C 250V 10A AUPO TCO Thermal Cutoff Fuse BF172 With Metal Casing

 

 

PRECAUTION FOR LEAD CONNECTION


* Be careful to be free from damage, burn, nick, crack or overheating at TCO seal or body.If there are such damage as above, do not use.


* Experimental assembly trials should be made to check the damage of lead wire, seal or TCO body.


* When connecting wire to TCO, it is recommended that splice or terminal shall be used. The material of splice or terminal should be corrosion resistant.


* When securing the splice or terminal to TCO, be careful not to damage the TCO body. The material of splice or terminal should be low heat resistace. Be careful not to cause excessive overheating due to poor connection method. It should be noted that the connection wire shall be flexible standard wire. If using solid wire, use the bending process.

 

 

SOLDERING OF LEAD


The following points should be noted if soldering is used to connect TCO lead.


* Do soldering work on lead as far away from the TCO body if possible.


* Be careful to minimize the heat transfer to TCO body. When proper means to prevent the heat transfer is not provided, TCO seal or body may be damaged and broken-down.


* To shorten the working time, employ pre-soldering process at the intended soldering area.


* Soldering Method to prevent heat.(use heatsink)

* Mechanical security must not depend on solder alone.


* Electric current must not pass through inner electric contact or the case of TCO when soldering. The passing of excess current damages the TCO element or case.

 

* Tensile strength of lead
Pull force shall not be over 2kg and push force shall not be over 0.5 kg.


* Strength of Case
Applying the excessive force to tie the case body causes deformation and effects normal operation of TCO.Since this may cause the fuse to not properly operate, be sure to avoid the excessive tying force.


* Functioning Temperature Test
Install the TCO in a chamber and gradually increasing temperature upto 20°C lower than Tf, then if the temperature of the chamber and the testing products are made equal, the temperature is increased 1°C per minute, then the fuse will function within the specified tolerance.


* Temperature Increase Test
When normal operating voltage and current are applied to the TCO in ambient temperature (20~25) °C the temperature of the TCO will go up.But the increase of temperature shall not be more than 10°C


* Insulation Resistance
After having operated in temperature test, the insulation resistance shall be more then 0.2 ohms when tested with 500V resistance measuring machine.


* Contact Resistance Test
The resistance of the both leads of the TCO should not exceed 1.5 ohms within the 10mm length of the leads.


* Dielectric Voltage Withstand Test
After conducting the Insulation resistance test, the TCO shall be maintained without breakdown when AC 500V is applied between the leads of the TCO for 1 Min

.

* Humidity Test

After keeping the TCO in the chamber with humidity 90~95% and specified below condition for 500 hours, the TCO shall pass the Functioning temperature test.

 

Tf Chamber Temperature Humidity
100 °C less 40 ± 2 °C 90~95%
100 °C over 65 ± 2 °C

 

*Aging Test

After keeping the TCO at the temperature 20 ± 3 °C lower then the Tf for 48 hours,the TCO shall pass the Functioning temperature test
