Abstract: A device (1) for providing protection for an electrical installation against overvoltages including at least one protection component (2), the device having a first mounting (14) delimiting a first interstitial space (14?) with a dimension fixed by construction that at least partially houses a first conducting element (10) and a second conducting element (11) to make the electrical connection between the first conducting element and the second conducting element, the device also having a second mounting (15) delimiting a second interstitial space (15?) with a dimension fixed by construction that at least partially houses a third conducting element (12) and a fourth conducting element (13) so as to make the electrical connection between the third conducting element and the fourth conducting element.

Abstract: A device (1) for protecting an electrical installation from overvoltages, having at least one protection component (2) and disconnection means (3) capable of changing from a closed configuration to an open configuration, as well as signaling means (5) capable of indicating the configuration of the disconnection means (3). The disconnection means (3) and the signaling means (5) respectively comprise a mobile disconnection element (4) and a mobile signaling element (12) arranged such that, when going from the closed configuration to the open configuration, the mobile disconnection element (4) moves in a rotational movement according to a first trajectory and cooperates with the mobile signaling element (12) to drive the mobile signaling element in rotation along a second trajectory different from the first trajectory.

Abstract: A device for protecting an electrical system against surge voltages, comprising one or more protection components (10), means (20) for disconnecting the protection component (10) and means (30) for visually indicating the state of the component (10), operationally connected to the disconnection means (20) and comprising at least one control part (40) and at least one means (50) for indicating the state of the protection component (10), combined with the control part (40), whereby the relative arrangement of the control part (40) and the disconnection means (20) is such that, when the disconnection means are opened (20), the disconnection means release the control part (40), thereby allowing the control part to move.

Abstract: A device (1) for protecting an electrical installation (2) from overvoltages, including at least one protection component (3), and disconnection element (4) capable of ensuring the electrical disconnection of the protection component from the installation by moving from a closed configuration to an open configuration, wherein the device (1) has at least one first fuse element (7) and one second fuse element (8) capable of holding the disconnection element (4) in the closed configuration, and wherein the disconnection element (4) includes at least one first contact surface (4A) and one second contact surface (4B) substantially intersecting with one another and to which the first and second fuse elements respectively adhere when the disconnection element (4) are in the closed configuration, to distribute the stresses exerted on the fuse elements and reinforce the mechanical strength of the disconnection element.
