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.

Modular intelligent electronic device (IED) with convection cooling

A component feeder including a lift for elevating a selection of components from a bulk storage, and a pick surface adjacent to the lift for receiving the selection of components. A spreader gives the selection of components a push for spreading the selection of components from the lift on the pick surface. The combination of a vertical lift and a separate pick surface adjacent to the lift enables the bulk storage being positioned right below the pick surface. The area of the pick surface is large in relation to the total footprint of the component feeder.
