Abstract: A plug-in unit assembly is disclosed which includes a case and a plug-in unit arranged to be removably connected to the case. The plug-in unit includes a unit body, a handle and an actuating member. The handle is pivotally connected to the unit body and operationally connected to the actuating member, the actuating member being movably connected to the unit body. The case includes a locking counterpart element and a releasing counterpart element, each of which is adapted to co-operate with the actuating member for moving the plug-in unit. The locking counterpart element is adapted to move the plug-in unit to a plugged-in position, and the releasing counterpart element is adapted to move the plug-in unit to an outer releasing position.

Abstract: A fastening arrangement for detachably fastening a component (2) to a frame part (4). The arrangement comprises a handle means (6) pivoted to the frame part (4) and an arranged to turn about its pivoting axis (12) between a normal position and a release position, and locking means (14, 16) arranged such that when the handle means (6) is in its normal position, inserting the component (2) into its position arranged in the frame part (4) causes the component (2) to be locked into the frame part (4). The arrangement also comprises means (18, 20) for opening the locking and arranged such that turning the handle means (6) to its release position releases the locking of the component (2) in relation to the frame part (4).

Abstract: A fastening mechanism for fastening a casing (2) into an opening in a wall (4), the mechanism comprising a collar element (6) fastened to the casing and arranged to be in contact with a first side of the wall, a pressing element (8) arranged to be in contact with a second side of the wall, the collar element and the pressing element being arranged to co-operate to direct a pressing force towards the w all, and a screw means (10) arranged to move the pressing element. The pressing element is arranged to rotate between a normal position and a mounting position; in the normal position the pressing element is capable of coming into contact with the second side of the wall to achieve a force keeping the casing (2) in place and in the mounting position it allows the casing to be pushed into the final mounting depth.

Abstract: The invention relates to a plug-in unit assembly comprising instrument transformers, a case assembly (1) comprising a connector assembly (10), and a plug-in unit (2) comprising at least one instrument transformer (3, 4) and configured to be connected to the case assembly (1). The instrument transformers (3, 4) of the plug-in unit (2) are coded in such a manner that the codings of the current transformers (3) and the voltage transformers (4) are different. The connector assembly (10) of the plug-in unit assembly of the invention is capable of identifying the type of the instrument transformers (3, 4) and based on their coding when the plug-in unit (2) is being connected to the case assembly (1).

Abstract: A plug-in unit assembly comprising a case (1) and a plug-in unit (2) arranged to be attached thereto, and locking means (4, 5) having a locked position and an unlocked position. The plug-in unit (2) comprises handle means (3) pivoted to turn around a pivoting axis (9). The handle means (3) have a normal position and an unlocking position for the locking means (4, 5), the turning of the handle means (3) to the unlocking position of the locking means resulting in the locking means (4, 5) moving into the unlocked position. The handle means (3) also have a detaching position for the plug-in unit, whereby turning the handle means (3) from the unlocking position of the locking means to the detaching position froth plug-in unit makes the plug-in unit (2) move a predetermined distance (D) outwards from the case (1).

Abstract: An arrangement for attaching electrical inductive components to a terminal block of a mounting base utilizes interlocking male and female plug-in connections. In instances where the electrical inductive components are measuring transformers, the arrangement accommodates higher electric currents in the area of several amperes seen in the primary winding because a galvanic connection is established simultaneously when the mechanical connection is made. Accordingly, the wiring of the primary circuit is made rapidly and without the possibility of faulty coupling. As the number of electrical inductive components increases, the arrangement disclosed provides compact construction.
