ABB SACE. They can fitted with the various terminal kits and all
the accessories com the SACE Emax range. These non
automatic circuit-breakers are specially suitable for use bus ties main isolators direct current
systems, such applications involving electric traction.
They are available fixed and withdrawable, three-pole and four-pole versions.
By connecting three breaking poles series, possible achieve rated insulation voltage of
750V DC, while with four poles series the limit rises 1000V DC
