DC-Alloy Thermal-Link / DC-Alloy Thermal Cutoff (DC-ATCO) is defined as
a non-resettable protective device functioning one time only. It is widely
used in electrical equipment and electric vehicle DC-ATCO is mainly consist
of Thermal Element, Flux Resin, Case, Sealant and Lead Wires. Normally,
thermal element is jointed to the two lead wires. Under abnormal conditions,
when the temp. reaches to the fusing temp. of DC-ATCO, the thermal
element melts and quickly retracts to the two lead wire ends with the aid of
the flux resin and disconnects the circuit completely.
