In a device for pivotally mounting a terminal block on a support, in particular on an interface module case in a programmable controller, the terminal block is mounted on the support by nesting engagement with a rotary member articulated to the support. The articulated member and the terminal block carry complementary coding pegs associated by movement in translation.

An electronic thermal relay is disclosed which can be associated with a multiphase electric load for generating a pre-alarm and/or an order for cutting off the power supply to the load in the case of a current overload in at least one phase or an imbalance between phase currents. With each phase is associated a thermal element with a resistive heating element through which the phase current flows, a resistive sensor transmitting to a signal processing circuit a signal representative of the heating and a thermal memory mass. The heating element is thermally coupled to the sensor and to the memory mass by a coupling body whose thermal inertia is less than that of the memory mass.
