Protection
Only in some cases there is a built-in device protection in form for instance of a fusible in electrical devices (for instance in a halogen lamp to prevent damage from use of too high power bulbs) or in form for instance of a pressure relief valve in hydraulic devices (e.g. a pressure cooker); many others have no protection (most hair-dryers) and the user realizes that the duty short time is over after for example the overheating has already damaged the device.
