An electronic control device enables a load to be separated from a power supply network for a time corresponding to the period which the load would cause a major disturbance in the network due to the state of the load at the time of a temporary main outage. The electric circuit control device comprises a first, normally open controlled switch (2) connected in the electric circuit, a second, normally closed, controlled switch (4) shunted with the first controlled switch (2), a power supply network (6) for supplying power to the control device, first time delay control network (17) connected to the first controlled switch (2), second time delay control network (30) connected to the second controlled switch (4) and memory network (41) connected to the second controlled switch (4), the time delay of the first control network (17) being at most equal to the time delay of the second control network (30).
