Abstract: A unipolar switching module made of insulating material and including an incorporated thermomagnetic tripping set, and/or a current measurer and power supply set for an electronic controller A multipolar low-voltage molded case circuit breaker can include unipolar switching modules, which interact with the tripping set and/or the current measurer and power supply set.

Abstract: A rotating handle device formed by the the mounting of an assembly including an attachment base that receives a grip and a sliding button, a sliding limiting drive member, and a fixing cover. The fastening between the sliding button, grip, attachment base, and fixing cover is achieved by pressure fastening engagements snap-fits. The assembly includes a mounting method that prevents removal of the grip from the attachment base unless the sliding button is removed first, and a mounting or dismounting process between the grip and the attachment base that may only take place upon the coincidence between pairs of flaps and passing recessions.

Abstract: An engageable drive engageable operating mechanism for converting a movement of a linear translation operating handle to a rotating handle movement relative to the operative front face engageable with a molded-case circuit breaker. The mechanism includes an external rotating adapter external rotating operating member or alternatively an engageable drive engageable operating mechanism incorporating a handle assembly external rotating operating member, interchangeable with each other; and a gear, a support movable movement-converting support including a rack portion, and a structural support base, wherein the structural support base includes a built-in side opening chamber.

Abstract: The present invention relates to a circuit breaker (20, 40) comprising a handle (33) connected to a switching and trip mechanism (25) in the base unit (20a), and capable of opening and closing a system (24) of electrical contacts in normal operation, ensuring the interchangeability between a pluggable electronic trip module (20b) and/or a pluggable thermomagnetic trip module (20b), using the same structural base unit (20a). The device comprises a main electric circuit “1” and a secondary circuit “2” or “2b”, wherein the main circuit “1”, using a current transformer (29) in the base unit (20a) which converts a current flowing in the main circuit “1” of the power line (23) to power the secondary circuit “2” or “2b”, issues a trip command to protect the main circuit “1”, opening the contact system (24) when predefined current limits are exceeded.

Abstract: This application discloses an apparatus which may comprise an upper part including a main terminal, an auxiliary terminal, a movable core, a movable carrier, and contacts; and a lower part including an attachment base, a fixed armature, and a coil module. The coil module may include at least a pair of supports each with a cavity or a housing. Inside the cavity or the housing, at least one elastic element may connect a command terminal with a coil connection element.

Abstract: An electromagnetic switching device, with several distinct regions (10, 20, 30, 40), where each region separates and places the terminals and the connection means in an improved form which make easy the identification of the terminals for the user when the contactor is fixed inside the panel; where the first region (10), have function of fixing the contactor on the panel and also houses the electromagnet; a second region (20) comprising the power terminals (21); a third region (30) that houses the auxiliary terminals (31, 32) and the command terminals (33); a fourth region (40) that is used for the connection of accessories; the third region presents a clear distinction between auxiliary terminals (31, 32) and command terminals (33), given by the asymmetry created viewed from the top; combined with a proposed uneven disposition X1 and X2 of the command terminals (31, 32) and auxiliary terminals (33) viewed from the front in the same third region.
