Power Capacitors
Dimensions
MKK-DC/MKK-DCI/MKK-DCI-H:
Mechanical considerations and construction
The following table shows the available standard
dimensions. Deviations from these dimensions are
available upon request.
General description
The MKK-DC/MKK-DCI/MKK-DCI-H capacitors are
designed in rectangular cases made of austenitic
stainless steel. The cases are hermetically welded
and the surface is not painted. Fixing brackets and
bolts are mounted to fix the capacitor. Bolts are used
also for the ground connection.
Tolerances are indicated in the drawings as well as the
maximum thermal expansions during normal operation
conditions.
The label is located centered to the length and 50 mm
from the top of the case.
Different types of terminals are available for the
terminal connections.
Labeling: manufacturer (company logo), ordering code,
connection diagram, version, rated capacitance,
tolerance, weight, insulating voltage, IEC standard,
country of origin, month/year of manufacturing.
The capacitors should be exclusively handled by the
fixing brackets. In no case the terminals should be
used to lift the capacitor.

Capacitors will usually be mounted upright (terminals
on top), but can be mounted in any position keeping
a distance of 25 mm minimum between large facets,
to allow for thermal expansion and effective cooling.

Terminals and connections
Standard terminals are available as shown below.
Brass bolts, tinned, with different metrics in male and
possibility of female connection, are available upon
request.
Insulation material of the terminal is Epoxy according to
CTI 600.
The following table shows the maximum continuous
currents acceptable (for a temperature increase in the
terminals of +15 °C), the maximum torque and the
contact surface of standard terminals.
Other specific options are available upon request.
