The measuring assembly comprises at least one such measuring device and measurement and/or transmission electronics of the result of the measurements receiving data from the coil of the measuring device.

Abstract: A protection and control assembly includes a power terminal block having openings, and electrical switch devices having input side conducting connection strips and output side conducting connection strips that project from a horizontal connection area on the input side and output side, respectively, of the electrical switch devices along a vertical axis. The electrical switch devices are positioned adjacent to each other along a direction parallel to the vertical axis, and the power terminal block makes the electrical connection by clamping the output side conducting connection strips of a first electrical switch device with the input side conducting connection strips of a second electrical switch device.

Abstract: The invention relates to a protection and control assembly comprising a first and a second electrical switch device. Each device has a box (10,30) provided with input side (39b,19b) and output side (39a,19a) conducting connection strips that project on a horizontal connection area on the input side (34b,14b), and output side (34a,14a) respectively, of each box (30,10). The strips can be inserted in openings (44) in the removable power terminal blocks (40,50,60). The assembly comprises a common power terminal block (40) that makes the electrical connection by clamping the output side (39a) connection strips of the first electrical device with the input side (19b) connection strips of the second electrical device, thus providing a mechanical attachment between the two electrical devices.

Abstract: An electromechanical contactor that houses an electromagnet and a mobile contact carrier within one body. The electromagnet 20 is situated at the rear of the body 10 and a command wiring plane PB is situated at the front of the power wiring plane PA. The command terminals B and the control terminals C are arranged in a forward command/control terminal block 60. The coil terminals 26 are connected to the command terminals B by transverse conductors 27 housed in grooves made between an internal surface of the body and an external surface of an arch-shaped casing.

Abstract: The invention concerns a switching appliance comprising several main dual cut-out poles provided with fixed contacts housed in an arc box and mobile contacts located on a mobile contact-holder (30). The latter is equipped, for the main contacts, with main housings (31) aligned transversely to the direction (X) of displacement of the contact-holder (30), and, for the auxiliary contacts, secondary housings (32) aligned transversely to the direction (X) and located in front of the main housings (31). The contact-holder comprises between the main housings and the secondary housings a vertical insulating wall (35). The arc box consists of two half boxes (20, 40) assembled in a horizontal plane, so that one of the two halves provides guiding elements and stop elements for the contact-holder (30).
