Product Details

Home Electrical Appliances Thermal-link Radial Shape GP C3 115 °C 3 A 250 Vac,Tinned Copper Wire, Total Length 70mm

 

Alloy Thermal-link / Thermal Cutoff (TCO) is defined as a non-resettable protective device functioning one time only. It is wide-
ly used in electrical equipment. Alloy TCO is mainly consist of fusible alloy, flux, plastic or ceramic case, sealant epoxy and
lead wires. Normally, fusible alloy is jointed to the two lead wires. Under abnormal conditions, when the temp. reaches to the
fusing temp. of alloy TCO, the fusible alloy melts and quickly retracts to the two lead wire ends with the aid of the flux and dis-
connects the circuit completely. Rated Current 1 A to 200 A, Rated Functioning Temp. 76 °Cto 230 °C, with CCC, UL, CUL,
TUV, KTL, PSE, Approvals and RoHS, REACH compliant.

Thermal-link
Attention
The surface temp.of TCO less than the holding temp of TCO
 
The seal or body of TCO must not be burned or over heated.
 
Installationpositionofmechanicalperformancerequirements
 
Do not locate the TCO in a place where severe vibration always occurs.
 
Ensure that the lead wire is long enough, and avoid actions such as press, tensile or twist.
 
The seal or body of TCO must not be damaged.
 
Soldering
Hand Soldering
Soldering should be carried out according to table 1 & table 2
 
The thermal element of TCO is fusible alloy with low melting point, which is jointed with TCO lead wires. Improper soldering
operation (too high soldering temp. , too long soldering time, too short lead wire etc.) may transfer more heat to the thermal
element and TCO may open in advance.
 
When soldering conditions are more severe than those listed in table 1 & table 2, a heat sink fixture should be used be-
tween soldering point and TCO body.
 
When soldering, please do not pull / push or twist TCO body or lead wires.
 
After soldering, let it naturally cool for longer than 20 s. During cooling, never move the TCO body or lead wires.
 

Soldering

 

Soldering should be carried out under the soldering conditions listed in table 2.

Auxiliary heat sink fixture is required to avoid Thermal-link cutting off unexpectedly.

 

 

 

Wave Soldering
The wave soldering parameters as table 3, For reference only, when TCO is for practice use, you need to do
some validation experiments. For example, using X-RAY to see the fusible alloy of TCO whether damage
after wave soldering.
 

Mechanical Connection

Riveting

 

Suitable for the lead wire diameter (d) of TCO ≥1.2 mm .

Choose small resistivity riveting material and be riveted.

 

A flexible lead or lead with low resistance should be used to rivet the TCO.

Contact resistance should be minimal, Large contact resistance will lead to higher temp., TCO Functioning in advance

 

Crimping

 

Suitable for the lead wire of TCO is flat electrode.

Choose small resistivity crimping material and be riveted.

Crimping process, to ensure that the lead will not be reversed, sealing resin will not be destroyed.

       Contact resistance should be minimal, Large contact resistance will lead to higher temp., TCO Functioning in advance.
