SCHURTER Reflowable Thermal Switch (RTS) is designed to trip at >175°C, in addition to the existing variant set to trip at >210°C. The compact thermal SMD fuse protects power semiconductors by reliably and precisely interrupting a circuit at a pre-defined temperature. Device measures 6.6 x 8.8 millimeters, and protects against such conditions, while it sustains operating currents up to 130A at rated voltages of up to 60Vdc. Breaking capacity up to 400A at 24Vdc. Device is mounted using conventional reflow solder processes with temperature profiles up to 260°C, after which it is mechanically armed by depressing the top.
