SACE Emax Switch-disconnectors for
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.
The range covers all installation needs 1000V /6300A.5 52. These non
automatic circuit-breakers are specially suitable for use bus ties main isolators direct current
systems, such applications involving electric traction. They can fitted with the various terminal kits and all
the accessories com the SACE Emax range.5 105 105 143 143 143 143
1000 [kA] 52.
The switch-disconnectors the SACE Emax/E range maintain the overall dimensions and fixing
points the standard range circuit-breakers.They cannot,of course, associated with the
electronic releases, CSs and accessories for determining currents and for applications.
They are available fixed and withdrawable, three-pole and four-pole versions.5 105 143 143
Note: the breaking capacity Icu, means external protection relay, with 500 maximum timing, equal the value Icw (1s).
The withdrawable circuit-breakers should used together with the special version fixed parts for
applications 750/1000V DC.
