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 locking arrangement can be used for securing electric module cards between two side walls of a housing. The locking arrangement includes two side members for fixed arrangement with the respective side walls. An opening defined between the side members accommodates electric contacts of the electric module cards. A first and a second transverse member form a frame with the side members in order to lock the electric module cards within the housing. A locking mechanism is detachably connects at least one of the transverse members to at least one of the side members by means of a snap-fit.
