Abstract:
A fuse holder comprising a frame (2), spring means and limiter means (6), the frame (2) comprising a first contact member (8) and a second contact member (10) adapted to receive an end (18) of the fuse between them, the spring means being adapted to press the contact members (8, 10) against the fuse end (18) to achieve an electrically conductive connection between the contact members (8, 10) and the fuse end (18), and the limiter means (6) being adapted to define the largest possible depth of the fuse end (18) in the installation direction between the first (8) and second (10) contact members. The spring means comprise a substantially circular arch-formed ring spring (4) adapted to also serve as the limiter means (6).
Abstract:
The invention relates to an arrangement for attaching a switch (2) control shaft (1) to a switch (2) pipe shaft (3), where the control shaft (1) is mounted partly in the switch (2) pipe shaft (3) and tightened to the switch (2) pipe shaft (3) by a screw (4). The arrangement comprises a tightening piece (6). The screw (4) is arranged to act on the control shaft (1) through the tightening piece (6) so that when the screw (4) is turned, the tightening piece (6) is arranged to press the control shaft (1) against the pipe shaft (3) so that the control shaft (1) tightens fast between the tightening piece (6) and the pipe shaft (3).
Abstract:
A switching device module comprising a frame (2), the switching device module being adapted to be connected to another switching device module for providing a modular switching device. The frame (2) of the switching device module is provided with one or more wire troughs (8), each of which is adapted to receive at least one wire of an auxiliary circuit of said modular switching device.
Abstract:
A switching device provided with a neutral conductor and arranged for opening and closing an electric circuit, the switching device comprising a frame (2), through which the electric circuit's neutral conductor (4) having a first end (6) and a second end (8) passes. The neutral conductor (4) comprises a movable middle portion (10) that is arranged for breaking the neutral conductor (4) inside the frame (2), the movable middle portion (10) being movable with respect to the first (6) and the second (8) end of the neutral conductor (4) and located between them.
Abstract:
The present invention relates to a fused switch housing (1) suited to accommodate at least one fuse adapter (2) having a first and a second contact surface (10). The fused switch housing (1) comprises a first and a second set of terminals (15) for respectively connecting the fused switch to a first and a second external circuit, stationary contacts (12, 15, 16), and at least one moving contact (13). The fused switch housing also includes switching means cooperating with each of said moving contacts (13) for making an electrical connection between each of said first terminals (15) respectively with each of said first contact surfaces (10) as well as for making an electrical connection between each of said second terminals (15) respectively with each of said second contact surfaces (10) so that at least one of said connections with said contact surfaces is openable by moving said at least one moving contact (13) with the help of said switching means. Herein, at least one moving contact (13) is adapted to press directly against said first or second stationary contact surfaces so as to form an electrical contact.
