Notes
1)
The rated currents I
n
have been determined according to IEC/EN 60947
(switchgear standard) and generally relate to the max. defined cross-sections. They are given for general reference here.
The engineering standards which apply in each case must be observed.
2)
To 240 mm
2
can be connected depending on the make of cable.
3)
To 95 mm
2
can be connected depending on the make of cable.
