Switchboards

Suitable for DOL (Direct on Line) starting, switchboards are available in both low and medium voltage models:

Low Voltage

COS low voltage switchboards are designed for use with a step-down and a step-up transformer to achieve desired ESP motor voltage. They are available in standard NEMA sizes, including Size 3 (90A), Size 4 (135A), Size 5 (270A) and Size 6 (540A). Voltage ratings range from 380V to 600V.

Medium Voltage

COS medium voltage switchboards are designed for direct coupling to the ESP. They require a step-down transformer to achieve the desired ESP motor voltage and are available in voltage ranges from 1500V to 5000V.
