An active safety circuit with loads protected by solid state relays comprising several solid state relays ( 1, 2, 3 ) supplying loads, controlled in turn from a microcontroller ( 4 ) for opening said relays ( 1, 2, 3 ) in the case of an anomaly in said loads, comprising a fuse ( 5 ) inserted in a supply network ( 6 ) of relays ( 1, 2, 3 ) and a grounded shunt line ( 7 ) from one point ( 8 ) of the network ( 6 ) between said fuse ( 5 ) and relays ( 1, 2, 3 ), and a safety switch ( 9 ) controlled by said microcontroller ( 4 ) and inserted in the line ( 7 ). A temperature detector ( 10 ) is either associated to each relay ( 1, 2, 3 ) or is commonly shared by several of said relays ( 1, 2, 3 ), and the detector ( 19 ) is connected to the microcontroller ( 4 ).
