Connection terminals
Connection terminals allow the circuit-breaker to be connected to the system in the way most suited
to the installation requirements. By and large they consist of:
Q
front terminals: for connecting cables or busbars directly from the front of the circuit-breaker;
Q
rear terminals: for installing circuit-breakers in segregated panels with rear access.
Where possible, the terminals have laser marking on the surface indicating the tightening torques for
the correct isolation of cables and bars.
Fixed version
The part of the standard equipment, fixed version 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:
Q
extended front (EF);
Q
extended spread front (ES);
Q
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 with sections of up
to 240mm
2
can be connected to all the circuit-breakers. The pitch adapter is automatically
supplied when it is necessary (see table page 3/9);
