Xiamen SET Electronics Co., Ltd.

idea Thermal CutOff (iTCO) is a fuse that uses low melting point alloys as the electrical connection point of the main circuit, with built-in heater as the control circuit, to achieve controlled fusing function. idea Thermal CutOff (iTCO) is consist mainly of Thermal Element, Electrode, Flux Resin, Feed Heater, Alloy Thermal-Link and Lead wire, sealed in plastic or ceramic housings.

idea Thermal CutOff (iTCO) is mainly used in the protection of new energy security, and secondary protection for charging and discharge circuits. idea Thermal CutOff (iTCO) mainly uses two electrodes which are connected with the thermal element of the fusing elements as electrical connections with passive temperature-sensing fusing actions. At the same time, Built-in heater with independent over-temperature protection heats the thermal element, provides sufficient heat to the fuse, cuts off the main circuit and disconnects the control circuit to achieve self-protection.

SETsafe | SETfuse idea Thermal CutOff (iTCO) covers Rated Current from 20 to 270 A, Rated Voltage from 80 to 500 VDC, Rated Functioning Temp. 136 to 150 °C, with UL, cUL, TUV Approvals and RoHS, REACH compliant.
