Abstract:
1. An electric pole for a low-voltage automatic power circuit breaker, comprising: a fixed contact and a movable contact 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 said phase conductor, said current sensor generating sensing signals that are indicative of the intensity of the electrical current that flows through said phase conductor, said sensing unit being electrically connected to a protection unit of said automatic power circuit breaker, said protection unit being suitable to receive said sensing signals and to generate control signals for actuation means operatively connected to said movable contact and comprising at least one input section provided with one or more electrical input terminals; wherein said sensing unit comprises a second section, which is rigidly connected to said first section and is provided with one or more electrical output terminals that are electrically connected to said current sensor, said second section comprising connection means that are suitable to mechanically couple said second section to the input section of the protection unit, so as to provide a direct electrical connection between the electrical output terminals of said second section and the electrical input terminals of said input section, wherein said connection means comprise a first connector element that comprises one or more guiding walls and a back wall from which the electrical output terminals of said second section protrude, said guiding walls and said back wall forming a first receptacle that is suitable to accommodate a second connector element of said input section, so as to provide a direct electrical connection between the electrical output terminals of said second section and the electrical input terminals of said input section, in a plug-and-socket fashion.
