Description
The PACT Analog current transformers form a complete
range of bus-bar, plug-in and winding current transformers
for measuring AC currents with a range of 1 A to 4000 A.
Current transformers belong to a group of specialized
transformers and are used in those areas where currents
cannot be measured directly. Depending on the
transformation ratio, the primary current is transmitted to a
smaller electrically isolated secondary current.
PACT Analog current transformers can be used either as an
industrial version or as a transformer that can be officially
calibrated.
The calibration process involves additional costs,
which are specified in accordance with the
national table of fees.

Features
Safe isolation as a result of the test voltage of 12 kV
(1.2/50 µs) prevents a hazardous operating voltage
from being transferred to downstream components
Conforms to surge voltage category 3 as a result of the
test voltage amplitude
Routine test according to EN 50178
Also refer to additional information on "Safe
isolation"; see page 28.
PACT Analog current transformers are available in the
following designs:
– Winding current transformer (Ipn: 1 A to 40 A)
– Bus-bar current transformer (Ipn: 50 A to 500 A)
– Plug-in current transformer (Ipn: 50 A to 4000 A)
WARNING: Danger due to damaged current transformers
•
Before startup, check that the housing of the current transformer is not damaged.
•
Also before startup, check that there are no electrically conductive connections between the primary
conductor and the secondary terminals.
•
If a built-in current transformer is removed in order to be used in a different system, check the current
transformer for damage again.
WARNING: Danger due to voltage at open circuit
The output of the current transformer is a constant current source. In the event of an increasing load, the output
voltage thus increases and reaches its maximum at infinite load (i.e., with open secondary terminals).
•
Avoid open-circuit operation at all costs.
•
Note that unloaded transformers must be short circuited.
•
Only start up the current transformer once the secondary cables are connected on both sides.

Safety notes
WARNING: Danger due to damaged current transformers
•
Before startup, check that the housing of the current transformer is not damaged.
•
Also before startup, check that there are no electrically conductive connections between the primary
conductor and the secondary terminals.
•
If a built-in current transformer is removed in order to be used in a different system, check the current
transformer for damage again.
WARNING: Danger due to voltage at open circuit
The output of the current transformer is a constant current source. In the event of an increasing load, the output
voltage thus increases and reaches its maximum at infinite load (i.e., with open secondary terminals).
•
Avoid open-circuit operation at all costs.
•
Note that unloaded transformers must be short circuited.
•
Only start up the current transformer once the secondary cables are connected on both sides.
NOTE: Avoid material damage when grounding
In accordance with VDE 0414, current transformers and voltage transducers must be secondary grounded from a
series voltage of 3.6 kV. At low voltages there is no need for grounding, provided the transformers do not have any
large metal surfaces within reach.
•
Ground the current transformers at the k terminal block.
NOTE: Avoid damage due to improper mounting
Vibrations can cause the screws on the primary rail to loosen.
•
During mounting, tighten the screws on the primary rail support so that they cannot loosen as a result of
vibrations.
Condensation can cause short circuits on the screws of the primary rail.
•
Only start up the current transformer inside, where there is no condensation.

Selecting the optimum transformer
Once the technical specifications for the current
transformers required by the application have been defined,
the next step is to determine the transformer types.
The four main current transformer characteristics are:
1. Primary rated current (primary current Ipn)
2. Secondary rated current (secondary current Isn)
3. Capacity (power) in VA
4. Accuracy (class)
Power requirement of copper cables with a different
diameter

0.175
0.0070

0.1094
0.0044

0.0729
0.0029
The current transformer is selected first and foremost based
on the primary rated current Ipn, which can be up to 4000 A
(depending on the type) and the secondary rated current Isn.
This is either 1 A AC or 5 A AC at the output.
Isn at 5 A AC:
The accuracy (class) can be another important criterion for
selecting the correct current transformer if certain
specifications have to be met.
Isn at 1 A AC:
Special attention, however, should be paid to the calculation
of the rated power (in VA). Here it is important to take into
consideration all occurring loads of the measuring circuit for
optimum selection of the rated power of the current
transformer (see below).
7
Phoenix Contact offers an extensive range of current
transformer types. This means that several different types
may meet the prescribed technical criteria. The main
differences lie in the size and shape of the transformer
opening and in the external dimensions of the transformer
housing. This allows you to select an optimum current
transformer based on the size of the copper rail and the
space available in the control cabinet.
How do you choose the optimum current transformer?
Firstly, add together all occurring loads:
– Calculate the power requirement of the copper cable
(info: cable length x 2)
– Take into account the power requirement of the
connected devices
– Add the reserve requirement
P = 10 m x 2 x 0.175 VA P = 3.50 VA
P = 10 m x 2 x 0.007 VA P = 0.14 VA
Installation and connection
Current transformers from Phoenix Contact can be
positioned anywhere.
Thanks to the primary rail support of the PACT Analog
current transformer which can be pulled out, no edges
protrude from the housing. Instead all edges are flush. This
is the basic prerequisite for the parallel attachment and
positioning of the current transformers on the copper rail,
which thus enables currents and loads supplied via an
electric branch to be measured. To this end, a copper
sleeve (accessory) is inserted into the internal opening of
the current transformer, which creates a conductive
connection between the current-carrying copper rail and,
e.g., the securing lug of a downstream fuse. To increase the
air and creepage distances, an extended secondary
terminal cover (accessory) is placed over the connections of
the secondary terminals of the horizontal current
transformer.
The optimum current transformer is one which can
accommodate a maximum of 1.5 times the total load.
This is because underloads affect accuracy and impair the
overcurrent limiting protection, which protects the
secondary circuit from being damaged by excessive
currents.

Installing a current transformer
The current transformers can be installed in the following mounting positions:
1.
B
C
Vertically on the copper rail
In most applications, the current transformer is fitted directly
onto the copper rail.
• Slide the current transformer over the copper rail.
• Slide the primary rail support through the inner hole of
the current transformer (A).
• Insert the two screws on the left and right of the
transformer into the holes of the primary rail support until
they reach the copper rail and the pressure is such that
the current transformer is fixed in place (B).
• Attach the protective caps for protection against
accidental contact to the screw heads (C).

Vertically on the mounting plate
Two plug-in feet are included as standard accessories (see
page 21).
• Insert the plug-in feet underneath the transformer on the
right and the left (A).
• Place the current transformer on the mounting plate (B).
• Insert the screws through the openings of the plug-in feet
to secure the current transformer (C).

Vertically on the DIN rail
The current transformer can also be snapped onto the DIN
rail with the optional snap-on mounting (see page 21).
• Snap the snap-on mounting into the holes beneath the
current transformer (A).
• Snap the current transformer onto the DIN rail (B).

Horizontally on the copper rail
As a result of their flat shape, the Phoenix Contact current
transformers can also be fitted horizontally onto copper rails,
e.g., behind fuse rails.

This is possible with the following current transformer types:
– MCR-V2-5012-85... (see page 7)
– MCR-V2-3015-60... (see page 5)
– MCR-V1-21-44... (see page 4)

Insert a suitable copper sleeve (see page 21) into the
inner hole of the current transformer (A) to create a
conductive connection between the copper rail and the
fuse.
Attach the extended secondary terminal cover to the
secondary terminals (B) to increase the air and
creepage distances when the current transformer is
installed horizontally.
