A removable modular control device for a contactor apparatus having in a casing, power switches actuated by an electromagnet, the coil of which is connected to two external connecting terminals accessible from the exterior through two respective openings provided on the upper face of the casing, each of these terminals having one clamping screw accessible through one opening formed in the front face of the casing. The control device includes a selector which is lodged in an insulating case provided with two rigid projecting pins adapted to be clamped in the connecting terminals, this selector being connected between the projecting pins and input terminals disposed on the upper face of the insulating case.

Removable modular control device for a contactor apparatus

An apparatus for controlling an electric installation is obtained by assembling a removable modular control device on a contactor. The lower face of this control device is provided with two rigid projecting pins located so as to be engaged and clamped in two respective control terminals of the contactor. These projecting pins are connected to two respective input terminals provided on the upper face of the control device, by an electric circuit having an elementary function.

Apparatus for controlling and testing an electric installation

The invention provides a magneto-thermal device for overcurrent relays. The end of a core, whose axial position may be adjusted with respect to a mobile plate, placed opposite and pivoting about one end of the yoke, is secured against movement by a wedge which is guided in a groove belonging to a flange of the coil shell. This device may be used in any thermal relay where a stable and precise adjustment of the tripping current threshold is desired.
