Abstract: This control unit (20) presents a front face (22) extending on a front plane (P22) where at least one housing (201; 301; 401) configured to receive a functional module (200; 300; 400) in an assembled position opens. Contact pads (36) are arranged at the bottom of each housing recessed from the front plane, so that a clearance distance between each contact pad and the front plane is greater than a class 2 isolation distance under a voltage greater than 690 V. In the assembled position, each functional module at least partially closes the corresponding housing, so that a creepage distance between each contact pad and the front plane is greater than a class 1 isolation distance under a voltage less than or equal to 690 V.

Abstract: This insulation device (250) for a battery compartment (200) comprises a ribbon (260), which extends according to a longitudinal axis (A260) and which comprises a first insulation portion (261), which is electrically insulating, which is continuous along the longitudinal axis (A260), and which is configured to be interposed between a contact terminal (214) and a terminal of an electrical battery (212) in order to prevent the passage of current between the contact terminal and the terminal. The ribbon also comprises a second insulation portion (262) and a conduction portion (263), which is configured not to prevent the passage of current between the terminal and the contact terminal when the conduction portion (263) is interposed between the contact terminal and the terminal. The conduction portion is interposed, according to the longitudinal axis, between the first insulation portion (261) and the second insulation portion (262).

Abstract: Control Unit for an Electrical Circuit Breaker and Associated Electrical Circuit Breaker This control unit (20) presents a front face (22) extending on a front plane (P22) where a connection housing (301), closable by a cover (308), opens and which is configured to receive a connection module (300) in an assembled position. Contact pads (36) are arranged at the bottom of the housing. The connection module presents a front face (311A) with an output connector (316). In the assembled position, the closed cover extends a creepage distance between the output connector and the front plane beyond a class 1 isolation distance under a voltage less than or equal to 690 V. In the absence of the connection module, the closed cover extends a clearance distance between each contact pad and the front plane (P22) beyond a class 2 isolation distance under a voltage greater than 690 V.

Abstract: This battery module (200) is configured to be inserted into a battery housing (201) opening onto a front face (22) of a control unit (20) of an electrical circuit breaker. The battery module comprises an envelope (210) with a proximal wall (214), which is generally orthogonal to a main axis (A214), and a peripheral wall (216), which extends from the proximal wall and presents a continuous contour around the main axis, the proximal wall and the peripheral wall together delimiting a cavity (211) for receiving a battery (212). The battery module comprises a conductive element (220B), which is partially received in the cavity and is configured to be connected to a pole of the battery. The proximal wall and the peripheral wall together form a continuous portion of the envelope that extends from the proximal wall and according to the main axis, at a minimum distance (L240) greater than or equal to 14 mm.

Abstract: This control unit (20) comprises a casing (30) defining a front plane (P22) where a housing (401), configured to receive a communication module (400) in an assembled position, opens. Contact pads (36) are arranged at the bottom of the housing recessed from the front plane (P22), so that a clearance distance between each contact pad and the front plane is greater than a class 2 isolation distance, according to the IEC 947-1:2019 standard, under a voltage greater than 690 V. The communication module comprises an envelope (410), which delimits a cavity (411), configured to receive a wireless communication card (414) and which in an assembled position of the casing, closes the housing, so that a creepage distance between each contact pad and the front plane is greater than a class 2 isolation distance under a voltage greater than 690 V according to the IEC 947-1:2019 standard.

Abstract: This control unit (20) comprises a casing (30) comprising a rear sub-assembly (34) and a front sub-assembly (100), which is assembled to the rear sub-assembly, and which comprises a central portion (102) with two opposing transverse edges (111, 112). The front sub-assembly (100) also comprises fastening members (121, 122) while the rear sub-assembly (34) comprises complementary members (131, 132), which are configured to cooperate with the fastening members to secure the front sub-assembly (100) to the rear sub-assembly (34), so that the two transverse edges are blocked in translation relative to the rear sub-assembly (34) according to two respective opposite and divergent directions, while each of the transverse edges is free to rotate relative to the rear sub-assembly (34) around an axis parallel to the considered transverse edge.
