Abstract: An industrial system for measuring a physical quantity, related to an industrial process and/or application, comprising: first means for detecting said physical quantity and for transmitting first data and/or signals related to said physical quantity; second means for receiving said first data and/or signals, said second means being connected to said first means through one or more data/signal transmission lines; third means for reading said first data and/or signals and for programming said first means, said third means being detachable from said means and fixable in a remote position from said first means.

Abstract: Low-voltage circuit breaker exhibiting live levers operatively connected to a control device for opening and closing the circuit breaker, fixed live terminals and electric arc extinction chambers, there being provision for the levers, the terminals and an extinction chamber to be enclosed in half-shells constituting a pole, for the half-shells to be made from insulating material and for several poles to be clamped in a supporting frame.

Abstract: A circuit breaker with detachable electric contact, constituted by plates (2,3) which are blanked or cut so as to form adjacent contact laminae (14) which define a seat (6;) for the insertion of a fixed current conducting bar (11) and a movable seat (5) for accommodating a detachable current distribution bar (10); spring elements (9) being also associated with the contact laminae (14) in order to elastically preload the laminae.

Abstract: Electric circuit breaker with means for adjusting the contacts comprising, for each electric phase, moving levers having main contacts and arc-breaking contacts co-operating with main contacts and arc-breaking contacts provided on a terminal bar there being provision for the levers loaded by springs to be supported by a crank pivoting about a pin and for the crank to be operationally connected to a link-rod articularly joined to an operating shaft and for each end of the operating shaft to have translatable and position-adjustable supports.

Abstract: Current switch with moving contacts cooperating with fixed contacts comprising, for each electric phase, a crank, pivoting about a pin, and a link rod, operationally connected to the crank and to the mechanism for opening and closing the switch, there being provision for the contact-carrying levers to be fulcrumed in the lower part to a pin integral with the crank, for, above the pin, the levers to have, on the opposite side to the contacts, seats against which spring means bear, for the opposite ends of the spring means to bear against seats formed at the top on the side of the support of the crank, opposite the fixed contacts.

Abstract: Self-coordinated device for the control and protection of electric motors and electrical equipment, for example, comprising, in a housing (2), a single control solenoid (5), a magnetothermal release device (M), a movable main contact (4) with a double break for each phase, which main contacts (4) are mounted on a contact-carrying bar (25) which is slidable and elastically preloaded (31), with which there interacts a composite mechanism (A) for the control of circuit-opening comprising two interacting mechanisms (B; C). One mechanism (B) interacts with the control solenoid (5) for desired circuit openings and for current surges. Both mechanisms (B; C) cause circuit-opening when short-circuit currents occur, more precisely with a double pushing action on the contact-carrying bar (25). The mechanism (C) also interacts with a locking mechanism (D) interacting in turn with a control knob (3) for the manual opening of the main contacts (4).

Abstract: An electric switchboard for medium voltages provides for the insulation of the compartments by means of sulfur hexafluoride gas, and each compartment is subdivided into superimposed cells which are metallically separated from one another and are gastight. In the cells auxiliary isolators are also provided for electrically isolating parts of the compartment for the purpose of maintenance without putting the entire switchboard out of action.
