SIMOCODE 3UF Motor Management and Control Devices
2 system interfaces for connection of
• a current measuring module or current/voltage measuring
module
• expansion modules and
• an operator panel
Basic unit 2 is suitable for standard rail mounting or, with
additional push-in lugs, for fixing to a mounting plate.
Current measuring modules (current ranges)
The current measurement module is selected for each feeder
according to the rated motor current to be monitored. Various
current measurement modules for current ranges from 0.3 to
630 A are available for this purpose. The current measurement
module is connected to the basic unit by a connection cable and
is supplied with electricity by the basic unit through this connec-
tion cable. Current measurement modules up to 100 A are suit-
able for standard rail mounting or can be fixed directly to the
mounting plate by means of additional push-in lugs. Similarly,
current measurement modules up to 200 A can also be mounted
on standard mounting rails or be fixed directly to mounting
plates by means of fixtures integrated in the housing. Finally, cur-
rent measuring modules up to 630 A can only be mounted with
the integrated screw fixtures.
Note:
Current measuring modules for up to 100 A set current can be
mechanically connected to the corresponding basic unit and
mounted with it as a unit (one behind the other). For larger
current measuring modules, only separate mounting is possible.
SIMOCODE pro 3UF7
motor management and control devices
Current measuring modules for the following current ranges are
offered:
• 0.3 ... 3 A with straight-through current transformer
• 2.4 ... 25 A with straight-through current transformer
• 10 ... 100 A with straight-through current transformer
• 20 ... 200 A with straight-through current transformer or
busbar connection
• 63 ... 630 A with busbar connection
For motor currents up to 820 A, a current measuring module for
0.3 ... 3 A, for example, can be used in combination with a
3UF1 8 interposing/current transformer.
Current/voltage measuring modules (voltage range)
Current/voltage measuring modules have the same functions as
the current measuring modules. However, they can only be used
in combination with basic unit 2. They offer the same current
ranges for the rated motor current. Mounting on standard mount-
ing rails, on mounting plates or directly on the contactor is also
the same as with the current measuring modules. They can also
measure voltages up to 690 V in the main circuit, which is nec-
essary for calculating or monitoring power-related measured
variables. Current/voltage measuring modules have additional
removable terminals, to which the voltages of all three phases of
the main circuit are connected (3-pole). An additional 3-core
cable can be used, for example, to directly connect the main cir-
cuit from the busbar terminals of the current/voltage measuring
modules to the voltage measuring terminals.
Note:
Current/voltage measuring modules can only be mounted
separately from the associated basic unit 2. A current/voltage
measuring module can only be used with a basic unit 2, product
version E02 and later (from April 2005).
