Abstract: The invention relates to an arrangement for protecting a component (2) in a power supply circuit (1 ). The arrangement comprises determination of an electric quantity constituting a load on the component (2), which electric quantity (6, 6', 6") constituting a load on the component is determined repeatedly while the component is exposed to the load. The arrangement also comprises estimation (8) of instantaneous load capacity of the component (2), which estimation of instantaneous load capacity (9, 9') is performed using a limitation criterion (5, 5', 5") set for the load capacity of the component. This limitation criterion (5, 5', 5") indicates the longest possible operating time of the component (2) under a given loading condition. For the limitation criterion (5, 5', 5"), a representation (4, 4') with respect to the electric quantity (6, 6', 6") constituting a load on the component is provided, and a limitation criterion corresponding to the defined electric quantity (6, 6', 6") constituting a load on the component is derived repeatedly from the said representation (4, 4') while the component (2) is exposed to the load. The estimate of instantaneous load capacity (9, 9') of the component is thus determined on the basis of both the limitation criterion (5) defined substantially at the estimation instant (7) and the limitation criteria (5', 5") defined before this.
