(1) From XT1 to XT6, the same terminals of fixed circuit-breakers can be mounted on the fixed part if the adapter is installed.
(2) For the XT5 630A and the XT6 fixed part, the HR and VR have different codes

Connection terminals
Connection terminals allow the circuit-breaker to be connected to the system in the way most suitable
for the installation requirements. They consist of:
• front terminals: for connecting cables or busbars directly from the front of the circuit-breaker;
• rear terminals: for installing circuit-breakers in segregated panels with rear access.
Where possible, the terminals have a laser marking on the surface indicating the tightening torques for
the correct insulation of cables and bars.

Fixed version
The standard fixed version of the SACE Tmax XT circuit-breakers are supplied with front terminals (F).
However, they can be fitted with the following types of terminals as accessories thanks to the special kits:
• extended front (EF);
• extended spread front (ES);
• front for copper/aluminium cables (FCCuAI). A pitch adapter must be applied to the terminal zone of
the circuit-breaker to ensure that copper and aluminium cables can be connected to all the circuit-
breakers. The pitch adapter is automatically supplied when it is necessary;
• front for copper cables (FCCu);
• for flexible busbars (FB);
• multicable (MC);
• rear oriented (R).
