Medium Voltage Motor Control

Sept. 27, 2008
Here’s a product line I don’t get into very often–medium voltage motor control. 

That’s 4,160 volts to the uninitiated. Rockwell Automation has released a new product line–Allen-Bradley OneGear. It is called a “next-generation” of medium voltage motor control designed for use with full voltage and solid-state, reduced voltage applications. It supports up to 15kV.

The product uses both vacuum-contactor and circuit-breaker switching technology and is available with optional arc-resistant cabinets, which meet IEE C37.20.7 and IEC Type 2 protection. The OneGear product line offers remote monitoring, diagnostic capability, and in-depth motor protection for maximum motor utilization while avoiding damage and downtime.

The product line includes the full voltage nonreversing controller, intelligent protection systems, and 10kV to 15kV Smart Motor Control (SMC) Flex controllers featuring ArcShield cabinet design and Allen-Bradley PowerBrick technology.
