    Abstract: An electrical circuit breaker with separable electrical contacts includes a fixed electrical contact, a mobile electrical contact, that can be displaced between open and closed positions and including several electrical contact fingers, arranged aligned along a row and that can be displaced relative to the mobile electrical contact, several bearing members, each associated with a contact finger to exert a force on this contact finger in order to displace it. The bearing members associated with the contact fingers situated in lateral end zones of the row exhibit a higher stiffness than the bearing members associated with the contact fingers situated in a central part of the row.

    Abstract: A low-voltage multipolar circuit breaker includes a moulded housing including a main body that is divided into interior compartments, each associated with one pole of the circuit breaker, and a cover that is mounted on the main body covering a main face of the body. The circuit breaker includes, for each pole, electrical contacts that can be separated by a device of a switching mechanism and an arc-extinguishing chamber. For at least two of the poles, the main face includes an additional aperture, each placed directly above the spark guard of the corresponding pole and placing the arc-extinguishing chamber of this pole in communication with the interior volume delimited by the cover and the main face, and the cover is attached to the main body while leaving a peripheral opening between the cover and the main body, placing the interior volume in communication with the exterior of the housing.

    Abstract: An air circuit breaker includes two separable electrical contacts connected to electric current input and output terminals; and a chamber for quenching an electric arc, including a stack of splitter plates that are spaced apart from one another, and lateral walls placed on either side of the stack and including a thermosetting-resin impregnated polyamide woven and being devoid of glass fibres. The quenching chamber furthermore includes protective elements made of crosslinked polyamide, the elements being placed in junction zones between the lateral walls and holding plates, the protective elements covering corners of the splitter plates, which corners are adjacent to the lateral walls, so as to separate these corners of the splitter plates from the electrical contacts.
