摘要:
An electronic device (500) is described to be connected to an electrical installation and to be operatively associated with an electrical apparatus (100). The electronic device allows detecting an operative condition of the electric installation (for example, a failure) and generating a corresponding command signal based to which an operative condition of the electrical apparatus is changed. The electronic device is housed in an enclosure (501) independent of a further enclosure (107) of the electrical apparatus, and is provided with means for reversibly fixing the enclosure to the further enclosure.

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:
The present invention relates to finger-test safety electrical-current distribution bars. In particular, the present invention relates to an electrical-current distribution bar (1) comprising at least one strip (2, 2') which is a conductor of electrical energy, characterized in that it comprises, on at least one edge (7, 7', 8, 8') of the at least one strip (2, 2'), a profiled section (3a, 3b) made of insulating material such as not to permit frontal contact with the edge of the strip.
摘要:
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:
Electrical assembly comprising a circuit breaker having an operating element movable between an opening position and a closing position and a safety mechanism for moving the operating element from the closing position into the opening position when a malfunction occurs, an actuating device (103) for moving the operating element between the opening position and the closing position, means (115,116;159,160) for connecting the safety mechanism to the actuating device (103), the actuating device (103) including signalling means (224,228) and means (206,212,216,220) for activating the signalling means (224,228) when there is a non-voluntary movement of the operating element from the closing position into the opening position caused by the safety mechanism.
