The switch-disconnectors complete the range of apparatus for applications at 1150V in alternating current (AC). These circuit-breakers conform with the IEC 60947-3 Standards.
Circuit-breakers in this version are identified by the letters of the standard range, where the
rated service voltage is up to 690 V AC, plus “/E”, thus becoming SACE Emax/E MS. They are
derived from the corresponding standard SACE Emax switch-disconnectors.
They are available in the three-pole and four-pole, fixed and withdrawable versions in the same
sizes, with accessory options and installations as per the corresponding standard circuit-breakers. All the accessories available for the SACE Emax range can be used. Standard fixed parts
may also be used for circuit-breakers in the withdrawable version. As per the corresponding
automatic version, this range of Emax was tested at a voltage of 1250VAC.

ABB SACE has developed the SACE Emax/E MS range of switch-disconnectors for applications
in direct current up to 1000V in compliance with the international IEC 60947-3 Standard. These
non-automatic circuit-breakers are especially suitable for use as bus ties or main isolators in
direct current systems, such as in applications involving electric traction.
The range covers all installation needs up to 1000V DC / 6300A.
They are available in fixed and withdrawable, three-pole and four-pole versions.
By connecting three breaking poles in series, it is possible to achieve a rated voltage of 750V
DC, while with four poles in series the limit rises to 1000V DC.
The switch-disconnectors of the SACE Emax/E MS range maintain the overall dimensions and
fixing points of the standard range circuit-breakers. They can be fitted with the various terminal
kits and all the accessories common to the SACE Emax range. They cannot, of course, be
associated with the electronic trip units, CSs and accessories for determining currents and for
AC applications.
The withdrawable circuit-breakers should be used together with the special version fixed parts
for applications at 750/1000V DC.
