idea Thermal CutOff (iTCO)

The idea Thermal CutOff iTCO is a fuse that uses low melting point alloys as the electrical connection point in the main circuit, together with a built-in heater for the control circuit to achieve the controlled melting function. The idea Thermal CutOff (iTCO) mainly consists of a thermocouple, electrodes, flux resin, heating wire, alloy with thermal link and lead wires sealed in plastic or ceramic housings. The idea Thermal CutOff (iTCO) is mainly used to protect the safety of renewable energy and as secondary protection for charging and discharging circuits. It mainly uses two electrodes connected to the thermocouple of the melting elements as electrical connections, with passive temperature-sensing melting functions. At the same time, the built-in heating wire with independent over-temperature protection heats the thermocouple, provides enough heat to fuse, disconnects the main circuit and disconnects the control circuit to achieve self-protection. The idea Thermal CutOff (iTCO) covers rated currents from 20 to 270 A, rated voltages from 80 to 500 VDC and a rated operating temperature from 136 to 150 °C, with UL, cUL, TUV approvals and is RoHS and REACH compliant.
