Summary: | A monitoring-and-control drawer (138) for an electrical connection enclosure comprises a front part (300) comprising a ventilation grille (326), a back portion (348) at which a back ventilation region is provided and functional elements (362). The heat generated by the functional elements is removed by an air flow (FL1) which enters the functional unit via each air grating in the front part and re-emerges from the functional unit via the back ventilation region, having passed right through the functional unit. The back portion belongs to a base of the drawer to which the functional elements are attached and comprises a group of upstream connectors (354) connected to an electricity source, a group of downstream connectors (356) connected to an electrical load and a ventilation orifice (358) which is part of to the back ventilation region and which is located between the group of upstream connectors and the group of downstream connectors. |
