MKK-DC/MKK-DCI/MKK-DCI-H:

Mechanical considerations and construction

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.

Different types of terminals are available for the

terminal connections.

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.

Standard design

Dimensions

The following table shows the available standard

dimensions. Deviations from these dimensions are

available upon request.

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.

Labeling: manufacturer (company logo), ordering code,

connection diagram, version, rated capacitance,

tolerance, weight, insulating voltage, IEC standard,

country of origin, month/year of manufacturing.

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.
