Special Contactors
Special contactors LC1DkK are designed for switching 3-phase, single or multiple-step capacitor banks; they conform to standards IEC 60070 and
60831, NFC 54-100, VDE 0560, UL and CSA.
Contactor Applications
Specification
Contactors fitted with a block of early make poles and damping resistors, limiting the value of the current on closing to 60 In max.
This current limitation increases the life of all the components of the installation, in particular that of the fuses and capacitors.
The patented design of the add-on block (No. 90 119-20) ensures safety and long life of the installation.
Operating Conditions
There is no need to use choke inductors for either single or multiple-step capacitor banks.
Short-circuit protection must be provided by gI type fuses rated at 1.7 to 2 In.
Maximum Operational Power
The power values given in the selection table below are for the following operating conditions.

Switching of multiple step capacitor banks (with equal or different power ratings).
The correct contactor for each step is selected from the above table, according to the power rating of the step to be switched.
Example: 50 kVAR 3-step capacitor bank. Temperature 50 °C (122 °F) and U = 400 V or 440 V.
One 25 kVAR step: contactor LC1-DMK, one 15 kVAR step: contactor LC1-DGK and one 10 kVAR step: contactor LC1-DFK.
