Schurter has added a low-trip-temperature variant to its RTS thermal fuse range, originally launched in 2018. Rather than >210°C, they are rated at >175°C. They have been developed to protect power semiconductors from over-heating – particularly from thermal-runaway when the semiconductors are in a confined space. In such an event, the thermal fuse interrupts the circuit, ...
