Description:

The ATCO Thermal-Link is a non-resettable protective device used in electrical equipment. It consists of a fusible alloy, flux resin, case, sealant, and lead wires. It functions by melting the fusible alloy under abnormal temperature conditions, disconnecting the circuit.

Applications:

Lamps
Switched-mode power supplies
Home electrical appliances
Batteries

Specifications:

The XG Series has a rated current of 3A and various models with different rated functioning temperatures (Tf) ranging from 76°C to 221°C. The devices are certified under multiple standards including UL, CAN-CSA, EN, and others.

Installation and Usage:

Ensure installation temperature does not exceed the maximum temperature limit (Tm).
Avoid placing in areas with severe vibration.
Ensure lead wires are not under stress or damaged.

Mechanical Connection:

Riveting should use materials with low resistivity.
Soldering should follow specified parameters to avoid premature functioning.

Packaging Information:

Available in bulk and taping options with specific dimensions and quantities.

Specifications and Procedures:

The document outlines the specifications for hand-soldering and wave soldering of ATCO components. It includes detailed tables specifying the maximum allowable soldering time and temperature for different lead wire lengths. The hand-soldering time varies based on the rated functioning temperature (Tf) and lead wire length (Ls), with auxiliary heat sink fixtures required for certain conditions to prevent unexpected cutting off of ATCO.

Hand-Soldering Time Table:

For temperatures ranging from 76°C to 230°C, the maximum soldering time is specified for lead wire lengths of 10mm, 20mm, and 30mm, with corresponding times increasing with temperature.

Lead Wire Forming Guidelines:

When bending lead wires, maintain a specified distance between the body and bending point as per Table XG-3. Use appropriate tools to avoid damaging the product, and avoid tangential forces on the leads to prevent damage to the ATCO seal.

Wave Soldering Parameters:

The document provides parameters for preheating, wave soldering, and cooling times. For temperatures between 131°C and 230°C, specific preheating and wave soldering temperatures are recommended, with maximum allowable times for each stage.

Key Recommendations:

Use auxiliary heat sink fixtures when necessary.
Avoid cutting, nicking, or sharply bending lead wires.
Ensure proper handling to prevent damage to the ATCO seal.

Figures and Tables:

Figure XG-1 and XG-2 illustrate the soldering and fixing positions, respectively.
Tables XG-1, XG-2, and XG-3 provide detailed specifications for soldering times, temperatures, and lead wire forming distances.

Catalog excerpts

Description Alloy Thermal-Link / Alloy Thermal Cutoff (ATCO) is defined as a non-resettable protective device functioning one time only. It is widely used in electrical equipment. ATCO is mainly consist of fusible alloy, flux resin, case, sealant and lead wires. Normally, fusible alloy is jointed to the two lead temp. of ATCO, the fusible alloy melts and quickly retracts to the two lead wire ends with the aid of the flux resin and disconnects the circuit completely.

Mechanical Connection Riveting 1. Choose small resistivity riveting material and be riveted. 2. A flexible lead or lead with low resistance should be used to rivet the ATCO. Soldering Hand-Soldering 1. Soldering should be carried out according to Table XG-1. 2. The thermal element of ATCO is fusible alloy with low melting point, which is jointed with ATCO 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 ATCO may open in advance. 3. When soldering conditions are more severe...
