Abstract
A method for the overload protection of devices which cannot endure continuous running on account of heat loss, to avoid a complex, cost-intensive direct coupling of the device to be protected to a temperature measuring element. The inside temperature within the housing of the device is merely measured and, on the basis of device-specific characteristics stored in an evaluation circuit, a permissible operating period assigned to the inside temperature is calculated. The permissible operating period is then used as a basis for the preset operating period cycle time.
