Abstract: This invention pertains to an automatic single- or multi-pole circuit breaker (1) for use in lowvoltage applications. The circuit breaker (1) includes at least a first fixed contact (10) that is coupled/uncoupled with a first moving contact (20). The latter is operatively connected to an operating mechanism (5) that enables its displacement. The circuit breaker (1) according to the invention includes a kinematic tripping device driven by means of a first separating movement of the moving contact (20) away from the fixed contact (10). The kinematic tripping device includes an operative member capable of tripping the operating mechanism (5), which in turn takes effect on the moving contact (20), thus determining a second rapid separating movement until the circuit breaker tripped position is reached.

Abstract: The present invention relates to a connection device for low-voltage switches (1), which is particularly suited for low-voltage automatic switches both in the fixed version and in the withdrawable version. The device comprises a first terminal board (10) positioned on a corresponding switch (1) and comprising a plurality of terminals for electrical connection to one or more devices or accessories inside the switch and one or more cable clamps (20) for connection between said terminals and one or more corresponding connection cables. The cable clamp (20) comprises a shaped body (201) having a first end (202) shaped to couple mechanically and electrically with the first terminal board (10). Said shaped body (201) has a first opening (203) for insertion of a first connection cable and comprises conductive means (204) positioned inside for electrical connection between the terminals of the terminal board (10) and a corresponding connection cable.

Abstract: An electronic tripping device for low-voltage circuit-breakers comprises means for detection and calculation of a ground-fault current operatively connected to tripping means of said circuit-breaker. The means for detection and calculation comprise: current-sensor means, which supply, for each pole, a signal proportional to the current; means for detection of the sign of the current, which, for each pole, supply a signal representing the sign of the current; current-rectifying means, which, for each pole, supply a rectified signal proportional to the current circulating in said pole; and first numerical-processing means, which supply a value with sign representing a ground fault by means of a numerical-processing operation comprising the multiplication of the signal representing the sign by the corresponding rectified signal.

Abstract: A painting booth, which includes: a frame which supports a plurality of movable walls (3) made of deformable material, whose internal surfaces bound a volume which can contain objects to be painted; at least one distributor arranged inside the volume and suitable to distribute painting powders meant to be applied to the surface of the objects to be painted; and removable means (10) which are suitable to interact operatively with the movable walls, so as to facilitate the removal of residual painting powders which deposit on their internal surfaces; and actuation means (6, 7, 11) which are suitable to move the movable walls with respect to the removal means. The actuation means include coupling means (11) for coupling to the movable walls, which are suitable to move the movable walls so as to keep the internal surfaces constantly taut.
