Thermal-Link (ATCO)-Alloy Type 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 wires. Under abnormal conditions, when the temp. reaches to the fusing 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. SETsafe | SETfuse Thermal-Link (ATCO)-Alloy Type KM series Rated Functioning Temp. from 125 ℃ to 150 ℃, Rated Current: 2 A, safety certification Includes UL, cUL, TUV, PSE, VDE, KC, CCC, and complies with RoHS and REACH. Features ● Non-Resettable ● High Accuracy of Functioning Temp. ● RoHS & REACH Compliant Applications ● Lamps ● Switched-Mode Power Supplies ● Home Electrical Appliances ● Transformers ● Motors ● Batteries Customization ● Other Temp. ● The Length of Lead Wires ● Taping Packing Available ● Lead Wires can be Insulated ● Tinned Copper Wires or CP Wires ● Leads Forming Types Soldering Hand-Soldering 1. Soldering should be carried out according to Table T-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.
