Abstract
The invention concerns a protection relay, in particular of the thermal type, recessed relative to its front face (24), a recess acting as through passage for interconnection of the conductors (C) between the terminals of the relay control (23) and of the contact switch (16). The recess (27) is concealed in normal operation by a shutter consisting of a flap (26) or a fixed part (26′) of the housing (20).
