Patent number: 8044312Abstract: An electrical service device having a housing is disclosed, in which voltage-carrying components are accommodated which are accessible via openings in the housing of the service device. At least one opening can have at least one wall-like insulating barrier associated with it which consists of an electrically insulating material and with which it is possible for the air gaps and leakage paths between two adjacent openings to be increased. The insulating barrier can be fixed to the housing of the service device.Type: GrantFiled: August 11, 2005Date of Patent: October 25, 2011Assignee: ABB Patent GmbHInventors: Alexander Orban, Richard Kommert, Matthias Bitz

Patent number: 7980903Abstract: An installation switch has an insulating housing and a terminal connecting arrangement for clamping a connecting conductor having an annular terminal shoe. The terminal connecting arrangement includes a terminal socket having an interior disposed between an insertion opening for receiving the terminal shoe and an access opening and a terminal screw having a screw head and a screw shank disposed in the interior of the terminal socket, the screw being actuatable in a longitudinal direction within the interior of the terminal socket between an open state and a clamped state. The arrangement further includes a connection plate having a screw hole with interior threads for threadably engaging the terminal screw when in the clamped state and a retaining device preventing the terminal screw from being removed from the terminal socket when in the open state.Type: GrantFiled: March 11, 2010Date of Patent: July 19, 2011Assignee: ABB AGInventors: Matthias Bitz, Ralf Kraus, Klaus-Peter Eppe

Patent number: 7704105Abstract: An installation switch having a housing and a connecting arrangement for a conductor having a terminal shoe. The connecting arrangement includes a socket having an interior, an insertion opening, and an access opening, and a screw having a screw head and a screw shank disposed in the interior of the socket. The screw is actuatable longitudinally between an open and a clamped state. The arrangement further includes a connection plate having a screw hole with threads for threadably engaging the screw when in the clamped state, and a retaining device preventing the screw from being removed when in the open state. The arrangement is configured so that the open state allows the shoe to be inserted into the insertion opening, the clamped state provides the screw being engaged with the shoe, and access to the screw is provided via the access opening of the socket to actuate the screw.Type: GrantFiled: August 20, 2008Date of Patent: April 27, 2010Assignee: ABB AGInventors: Matthias Bitz, Ralf Kraus, Klaus-Peter Eppe

Patent number: 7683277Abstract: The invention relates to a connector element for two installation breakers, adjacently attached with the broad faces thereof in contact, in particular, power breakers or residual current breakers, the housings of which are each formed from two dished housing pieces. The connector element comprises an approximately cylindrical base body with a first external diameter on the front side of which two radially-sprung, axially projecting first and second expanding arms are moulded. The external contours of the spreader arms lie on a cylindrical outer surface, the external diameter of which is smaller than the first external diameter of the base body. The free ends thereof comprise radially projecting lugs on opposed external lines, which, in the assembly state, clip behind recesses on the housings, for connection by means of the connector element, of adjacent installation breakers.Type: GrantFiled: August 23, 2005Date of Patent: March 23, 2010Assignee: ABB Patent GmbHInventors: Rudolf Sellner, Matthias Bitz

Publication number: 20090260964Abstract: The invention relates to an electric installation device comprising a housing (11) that contains current conductive components, said components being accessible via openings (27; 60, 61) in the housing (11) of the installation device. At least one partition-type insulation barrier consisting of electrically insulating material can be allocated to at least one opening (27; 60, 61), thus increasing the clearances and creepage distances between two neighbouring openings (27; 60, 61). The insulation barrier can be fixed to the housing (11) of the installation device.Type: ApplicationFiled: August 11, 2005Publication date: October 22, 2009Applicant: ABB PATENT GMBHInventors: Alexander Orban, Richard Kommert, Matthias Bitz
