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.

By connecting three breaking poles series, possible achieve rated insulation voltage of 750V DC, while with four poles series the limit rises 1000V DC
