Yes, the RCS 1350 raclette grill is a fully-fledged table grill that is also equipped with a raclette level. The heating element has a powerful 1300 watt output and the appliance reaches a temperature of 220 - 230 °C on the grill plates at the maximum setting. This is definitely sufficient for searing.
Important: After switching on, you must give the grill plates enough time to heat up thoroughly before you start grilling. (But you already know this from other grills).
