FOUR-POLE LOAD SWITCHES OF DOUBLE ACTION I-0-II WITH MOTOR 220-240VAC (MOTORISED) & CONTROL ELECTRONIC BOARD. The CKM series refers to four-pole changeover switches of double action with motor I-0-II & is available in three versions:

• Without electronic control board
• With electronic control board
• With microprocessor unit

The electronic control board allows for easy connectivity, includes a manual/automatic operation selector switch, provides fault control & indication via LEDs, and has available contacts for remote operation status indication.

The microprocessor unit allows the changeover switch to automatically switch from position I (main circuit) to position II (generator) upon the interruption of the main supply and revert to position I when the main supply is restored. A key-operated manual lock is available to prevent manual operation on the rotary shaft when the CKM switch is controlled remotely.
