SACE Tmax XT switch-disconnectors

Switch-disconnectors are devices created from the corresponding
circuit-breakers and feature the same overall dimensions, versions,
and can be fitted with the same accessories.

Applications Utilization category
These devices are mainly used as: Tmax XT disconnectors comply with utilization
• general disconnection devices in sub-switchboards; categories defined by IEC 60947-3 Standard.
• switching and insulation devices for lines, bus
bars or groups of apparatus;
• bus ties.
In the open position, the disconnector guarantees
a sufficient insulation distance (between the con-
tacts) to ensure safety and to prevent an electrical
arc from striking.
