Abstract: The present disclosure relates to an IED configured for use as a protection relay in an electric power system. The IED comprises a plurality of cassettes connected to a backplane, with at least two cassettes mounted adjacent each other. Each of the cassettes comprises a housing profile in the form of a rectangular tube having an envelope wall of a heat conducting material, and at least one electronic card arranged in a card slot within the tube formed by the housing profile, which at least one card is electrically connected to the backplane. Adjacent cassettes are separated a distance such that air canals are formed between their respective housing profiles.
