Medium Voltage Controllers

JK400 Series

The JK400 Series of motor controller is the result of extensive research and development. This state-of-the-art controller was designed in Houston, Texas, and is currently being manufac- tured under ISO 9001 standards in the same manufacturing facility as Toshiba motors and drives. The components in this new series have been arranged in the most logical manner to produce a tightly designed unit, and in the full voltage type starters, uses no internal power cables. This streamlined, space saving design provides the ultimate in maintenance ease and safety features.

These medium voltage controllers are available in across-the-line or reduced voltage models for the control of induction, wound rotor or synchronous motors, transformers, or capacitors up to 6.6kV. All controllers are designed to meet NEMA Class E2 requirements. These fixed type controllers are available in one or two high enclosures with the following standard features:
