Home Electrical Appliances Transformers Tf 102°C Fusing Temp. 10A ,16A,20A,Alloy Thermal-link Thermal Cutoff (TCO)

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, Approvals and RoHS, REACH compliant.
