IMPORTANT: it is possible to obtain different capacities for the connections by altering
the thickness and number of busbars in parallel.
The following tables provide some examples of the quantity and the sizes of the connections that can be used
for each type of circuit-breaker:

IMPORTANT: before proceeding with the connection between terminals and connection
busbars:
• make sure that the contact surfaces of the busbars are free of burrs, dents, traces of
rusting, dust or traces of grease.
• make sure, if aluminium busbars are used, than these are tin plated in the contact
areas.
• make sure that the busbars do not exert forces in any direction on the terminal.
• for tightening use M12 screws or threaded rods with resistance class 8.8 equipped
with spring washers and lock them with a torque of 70 Nm - 619.5 lb in.
NOTE: the information on the performances of the circuit-breakers in switchboards is available
