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
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.
