
Underscore (_) indicates magnet coil suffix required. See Table 65.
Notes:
Main Circuit: Depending on the
coordination type required (i.e. Type 1 or
Type 2) it must be established whether the
fuse protection and the input wiring for the
main and delta contactors are to be
common or separate.
Control Circuit: If the combinations are used
in the scope of the IEC/EN 60 204-1, VDE
0113 part 1, point 9.1.1 regarding the supply
of control circuits is to be observed.
IEC Utilization Categories, see Page 178,
Reference Data.
AC-1: Non-inductive or slightly inductive
loads.
AC-3: Squirrel-cage motors — starting,
switching of motors during running.
AC-4: Squirrel-cage motors — starting,
plugging, inching.
