Abstract
An electronic relay including current sensors (11, 12, 13) mounted, between terminals (L1, T1, L2, T2, L31, T3), in series on alternating current power supply lines to a load (M). A back of a case (1) of the electronic relay includes a power card (C1) linked to the current sensors (11, 12, 13) and connected via connectors to electronic daughter cards (C2, C3, C4) carrying lateral terminal blocks (B1 and B2) which have outputs in the lateral openings of the case. A front of the case (1) includes a dialogue and communication card (C5) connected to at least one of the daughter cards (C3).
