Sonoff Orb-ZBDIM Zigbee Dimmer Wall Switch: Yes
Catalog note
Overheat protection is one of the four safety badges on the product page, and the description says power is disconnected automatically when an abnormality is detected.

Overpower Protection

Lutron Caseta Diva Smart Dimmer Switch: No
Catalog note
An overload is caught by the thermal protection rather than by a separate power cutoff, so exceeding the wattage rating is prevented by the derating chart, not by the dimmer
