摘要:
The residual current device (2; 200) associable to an electric circuit-breaker (1), the residual current device (2;200) comprising: - interconnection electric terminals (22) suitable to establish, by co-operating with respective electric terminals of the circuit-breaker (1) that are accessible through a first face (6) of the latter, an electrical connection between the device (2;200) and the electric circuit-breaker (1); and - mechanical coupling means (15,16) suitable to allow a mechanical interaction between the device (2;200) and the circuit-breaker (1) through a second face (12) perpendicular to said first face (6). The device (2;200) comprises first (20,21;221) and second (24;220) parts, which are pivotally connected to each other and carry said interconnection electric terminals (22) and said mechanical coupling means (15,16), respectively.

The structure comprises an elongated box-shaped housing (10), a plurality of power metal bars (20) which are arranged in the housing (10) substantially perpendicular to the housing longitudinal direction and substantially parallel to each other, a plurality of interconnection metal bars (21) which substantially parallel to each other, each interconnection metal bar being connected to a corresponding power metal bar (20), a terminal board (12) attached to the housing (10) for electrical connection to a plurality of user electrical networks, a plurality of positions (11) on a wall of the housing for mounting and electrically connecting power meters, each position (11) having associated thereto a power meter input electrical connection group (16).
摘要:
Two unipolar switches (10), each enclosed in a box-shaped container made of insulating material, are designed for being mounted on a common support (40) with their respective sides parallel to each other and have connection terminals accessible from faces (13, 17) adjacent to the sides. In order to realize an electrical apparatus in which the two switches are shunted in high frequency by a by-pass device, each of the switch containers (10) is provided on at least one side (15) with an opening (20) corresponding to each of the connection terminals and the by-pass device (30)is enclosed in a box-shaped container of insulating material designed for being mounted with its sides (42) parallel to the sides of the switches (10) on the common support (40) and has two electric terminals (41) projecting from each side (42) in positions such that, when the by-pass device (30) is mounted on the common support (40) between the two switches (10), the terminals (41) can become inserted in the openings (20) on the sides (15) of the switch containers (10).
摘要:
A reset module (200) for an electrical safety device (100) is described having a drive lever to be manually displaced. The reset module comprises a cover that extends to cover the drive lever (112) and prevent any manual contact with the lever. The cover includes an element that engages the drive lever in order to cause, by manually moving the cover from a first to a second position, the switching of the device (100) from the closed to the opened state.

An electrical connection element (15) comprises a conductor (19) having, at a first end, a resilient clip-like coupling element (20) which establishes an electrical contact with a distribution bar (12) and, at a second end, a plug or socket connector element (21) complementary to that of the electrical device (14) to be connected to the bar. A box-like body (18) encloses the conductor (19) leaving its ends free for the respective electrical contacts.
摘要:
A safety device (100) for an electrical installation (IMP) comprises electrical contacts (2) suitable to be automatically opened and manually re-closed in order to disconnect/connect the installation from/to a network power line (LIN), and automatic release means (5) that can be actuated in consequence of a failure condition detection in the installation in order to command the automatic opening of said contacts. This safety device is characterized in that it further comprises control means (6) for performing measurements on the installation and that discriminate the nature of the failure. These control means can act on the release means in order to hold the device contacts opened and prevent the same from being manually re-closed upon a failure of a permanent type.
