Abstract: Various embodiments of conveyor system devices, such as sprockets and idlers, are disclosed. The conveyor components can comprise axial and/or radial openings that facilitate the discharging of debris and other contaminants, which can reduce wear and/or prolong component life. In some embodiments, the conveyor component ramps convey the debris and contaminants to the openings.

Abstract: An electric pole (1) for a low-voltage automatic power circuit breaker, comprising: a fixed contact (2) and a movable contact (3) that can be coupled/uncoupled with respect to each other, said fixed contact being electrically connected to a phase conductor, and a sensing unit that comprises a first section suitable to accommodate a current sensor associated with the phase conductor, the current sensor generating sensing signals that are indicative of the intensity of the electrical current that flows through the phase conductor, the sensing unit being electrically connected to a protection unit of the automatic power circuit breaker, the protection unit being suitable to receive the sensing signals and to generate control signals for actuation means operatively connected to said movable contact, and comprising at least one input section (14) provided with one or more electrical input terminals (141); whose particularity consists of the fact that the sensing unit comprises a second section (20), which is rigid

Abstract: A multipole current limiting circuit breaker comprising an insulating enclosure that contains: a) for each pole, at least one fixed contact and at least one movable contact, which can be mutually coupled/uncoupled upon closure/opening of the circuit breaker; b) actuation means which provide the energy for moving said movable contacts and determines their coupling/uncoupling with the corresponding fixed contacts, said actuation means comprising a rotating actuation bar that is operatively coupled to the movable contacts of the poles; characterized in that said movable contacts have a fork-shaped body having a base element that supports two arms provided with plates for electrical contact with corresponding coupling surfaces of the fixed contact, and in that said fork-like body is connected to the actuation bar by virtue of elastic means accommodated at least partially in a seat formed in the bar, said elastic means being anchored to said bar and being fixed to said base element so as to support the movable con

Abstract: A device for interlocking at least two single- or multipole circuit breakers, of which:—a first circuit breaker, suitable to be fixed to a mounting plate of the first and second circuit breakers; —a second circuit breaker, suitable to be fixed by virtue of fixing means to the first bracket and to be supported thereby;—an interlocking element, provided with a contoured body that is operatively coupled to the second bracket so that it can move with respect to it, the interlocking element being suitable to be rigidly connected to the second bracket, by virtue of locking means, in a chosen position in which it interacts operatively with at least the first opening/closure lever in a condition that corresponds to the opening of the first circuit breaker, preventing its movement and preventing the circuit breakers from being closed simultaneously.
