High Dependability and Low Voltage Switchboard

Okken is a low voltage switchboard designed for use in critical largesite applications : off-shore platforms, large industrial plants. Okken’s safety and high operational dependability are essential for your applications in critical processes, in power distribution as well as for motor control.
Okken is a totally type-tested switchboard, in accordance with IEC 60439-1, and certified by independent labs: LOVAG, ASEFA, CESI and VIRLAB.

A wide range of solutions

Withdrawable device for high power incomers or feeders up to 6300 A
Fixed for economical low-power feeder applications. Disconnectable up to 630 for a high upgradability

Plug-in up to 630 for fast interchangeability without handling the power cables
Drawers for highest availability and safety of electrical distribution and motor control

Okken High Safety and Availability Switchboard up to 6300 A

Okken's modular design makes it easier to use for main switchboard power distribution up to 6300 A, as well as for the control and monitoring of motors up to 250 KW. It allows a combination of different types of feeders in the same column.

High dependability and low voltage switchboard
Okken is a low voltage switchboard designed for use in critical large-site applications:

  • off-shore platforms
  • Large industrial plants

Okken offers different protection levels: IP31 / IP41 / IP54, appropriate to the environmental characteristics of your installation.

Drawers
