Fuse-Switch-Disconnectors
The FSW Fuse-Switch-Disconnectors, developed according to International Standard IEC 60947-3 and bearing CE certification, are applied in electric circuits in general so as to provide the disconnection and protection against short circuits and overloads by means of NH blade contact fuses.
In order to ensure a long lifespan, the FSW Fuse-Switch-Disconnectors are manufactured with reinforced thermoplastic materials and flame retardant. Additionaly, they feature contacts with silver coating, providing low power losses.
Selection of the Switch-Disconnector The switch-disconnectors are manufactured to use as conductor element (link) the blade contact fuses with dimensions established by standard DIN 43620, NH-type fuse. The switch-disconnector model to be used is directly linked to the dimension of the used fuse. Therefore, first a fuse housing (NH000 up to NH3) must be selected in order to define which fuse-switch-disconnector will be used.Secondly, you must check if the switch-disconnector is capable to carry circuit rated current. The current values are presented on page 4 and the rated current of the load must be lower than or equal to the maximum current of the switch-disconnector. The rated current of the fuse can be higher than the rated current of the switch-disconnector due to criteria to fuse dimensioning.
Safety and Simplicity WEG switch-disconnector has several characteristics which aim at increasing security for operation and maintenance of the equipment, simplifying diagnoses and fuse replacement:g The switch-disconnector allows checking the state of the fuses
through a transparent cover, besides featuring small openings which allow making electrical measurements without interrupting the operation.
g As per IEC 60947-3, the switch-disconnector can perform the non-frequent opening under load. The FSW series has arc chambers for the extinction of the electric arc and disconnects all the phases together, ensuring full insulation between the load circuit and power supply.
g In the opening of the switch-disconnector, the fuses remain fixed to the cover, preventing their drop or accidental contact between the energized parts. Furthermore, the cover is totally removable, allowing simple fuse replacement in a simple and safe area out of the electrical panel.
g The switch-disconnectors also feature a built-in auxiliary contact in order to indicate when they are open or not properly closed.
g As accessory, it is possible to mount terminal covers on the connecting terminals so as to reduce the risk of accidental contact with the power cables.
