BAR HOLDING ELEMENT 3P+Ν 2X10A SA503000 (SPI43)

Code: 118-033503000

VEMER/ITALY

Series of insulators designed to be used as a busbar support element in three-phase systems & three-phase plus neutral systems.

The insulator consists of two crossbars on which socket slots are obtained whose width , which can be completed with a simple and patented system of rider spacers , allows the different bar sections to be adapted by always keeping the axle base constant between the phases. Everything is fitted with threaded shafts, washers and zinc coated nuts for fastening to the frame and the clamping of the two crossbars. Made of polyester resin with the addition of a high percentage of glass fibres, they guarantee a high electrodynamic resistance over time in case of faulty currents and an excellent performance in contaminated atmospheres.
