Abstract:
An apparatus with remote control features for tripping off magnetothermal switches comprises at least one switch having a central core supporting trip-off linkages wherein a voltmeter coil is housed with each switch being connected to a respective one, e.g. a lamp, of user electric appliances.The apparatus also comprises a pushbutton control connected to each voltmeter coil in each magnetothermal switch for remotely and simultaneously operating the trip-off linkages to thus turn off simultaneously each electric appliance, while enabling function regaining by operating the corresponding switch locally.
Abstract:
An electrical apparatus that can be fixed to a supporting frame having a mounting window to receive the electrical apparatus includes a main body having a substantially box-like shape and first fixing elements provided on first and second opposite sides of the body to engage with corresponding second fixing elements the frame and facing the mounting window. The first fixing elements include guiding fixing elements to permit axial and guided sliding of electrical apparatus with respect to the frame in inserting the apparatus into the mounting window. The first fixing elements further include snap-in fixing elements to block axial sliding of the electrical apparatus with respect to the frame once a predetermined snap-in position has been reached.
Abstract:
The present invention refers to a support frame (2) for wall-mounting at least one electrical apparatus, the frame (2) comprising: —a frame body (7) fixable to the wall and developing about a window (9) defining a mounting seat adapted for receiving and holding said at least one electrical apparatus; and —fixing means (12) for removably fixing a cover plate (3) to the support frame (2). The support frame (2) is characterised in that the fixing means includes at least one fixing channel (12) exhibiting an end jointed to an opening (13) obtained in the frame body (7), the fixing channel (12) being such as to be capable of receiving, through the opening (13), a corresponding fixing tongue (4), provided in the cover plate (3), the fixing channel (12) including therein relief means (14) that can face a surface (31) of the tongue (4) and pushing means (20, 21) adapted for acting on the fixing tongue (4) for engaging pressure-wise said surface (31) of the tongue against said relief means (14) of the channel (12).

Abstract:
Electrical apparatus (1) that can be fixed to a supporting frame (2) provided with a mounting window (22) suitable to receive said electrical apparatus (1), the electrical apparatus (1) comprising: —a main body having a substantially box-like shape; and—first fixing elements (8,9,10) provided on a first (3) and a second (4) opposite side of said box-like body to engage with corresponding second fixing elements (27, 28, 29) provided on said frame (2) and facing said mounting window (22). The first fixing elements (8, 9, 10) of the electrical apparatus (1) include: —guiding fixing elements (8,9) such as to permit axial and guided sliding of said electrical apparatus (1) respect to said frame (2) in inserting said apparatus (1) into said mounting window (22); —snap-in fixing elements (10) suitable to block said axial sliding of said electrical apparatus (1) respect to said frame (2) once a predetermined snap-in position has been reached.
Abstract:
The present invention refers to a support frame (1) for wall-mounting one or more electrical apparatuses, the frame comprising a frame body (2) that can be fixed to a wall and extending around an opening (5) defining a mounting seat suitable for receiving and holding one or more electrical apparatuses. The support frame (1) is characterised in that it also includes: —at least one optical source (7.1, 7.2) suitable for generating an optical signal; —an electrical circuit (20, 10) connected to said optical source (7.1, 7.2) to supply it with an electrical power supply signal, —means (16.1, 16.2, 16.3) for housing said electrical circuit (20, 10) and said source (7.1, 7.2), foreseen in said frame body (2), the frame body (2) allowing the propagation of at least one part of said optical signal towards the outside of said body.
Abstract:
In a miniaturized automatic circuit breaker with a casing of insulating material forming an arc-extinguishing chamber and a housing for contacts which are closed and opened and for a pair of terminals for connection to ends of leads outside the circuit breaker, one of the terminals is multifunctional and comprises a screw clamp opening in a first face of the circuit breaker in order to receive ends of external leads and spring-clip terminal opening in the rear face of the circuit breaker for receiving a blade-like terminal of an external lead, and an insulating diaphragm is interposed between the multifunctional terminal and the arc-extinguishing chamber and forms, with the casing, at least one vent duct opening in the first face and insulated electrically from the multifunctional terminal.
