The switch-disconnectors the SACE Emax/E range maintain the overall dimensions and fixing
points the standard range circuit-breakers. These non
automatic circuit-breakers are specially suitable for use bus ties main isolators direct current
systems, such applications involving electric traction.
The range covers all installation needs 1000V /6300A.

applications 1000V DC
ABB SACE has developed the SACE Emax/E range switch-disconnectors for applications in
direct current 1000V compliance with the international IEC 60947-3 Standard. They can fitted with the various terminal kits and all
the accessories com the SACE Emax range.
By connecting three breaking poles series, possible achieve rated insulation voltage of
750V DC, while with four poles series the limit rises 1000V DC.
The withdrawable circuit-breakers should used together with the special version fixed parts for
applications 750/1000V DC.
They are available fixed and withdrawable, three-pole and four-pole versions.5 105 105 143 143 143 143
