The 3300 Volt switchboard is COSCO's most popular model,  operating effectively from 700 to 3300 volts. Such capability allows this model to be used on virtually any ESP installation making it a favorite for users requiring maximum flexibility and minimal inventory. Like all COSCO switchboards, it is CSA approved, and incorporates the highest quality components. When it comes to motor control, the customer may choose from a variety of options.

Minor changes allow the switchboard's 3300 maximum voltage rating to be increased to 3600 volts.

The low voltage compartment is mounted on the front of the high voltage door and contains the motor controller, indicator lights, selector switch and start button. Oversized compartments are available to house additional components such as SCADA devices. The door is weather sealed and finished with a three point lockable latch.
