Built-To-Order, 2 Week Shipment Solid State Reduced Voltage Starters4,160 Volt MVRMX Series 0 to 1,500 HP or 1,501 to 3,000 HP

Benshaw has analyzed and value engineered our MV SSRV Engineered-To-Order product options, and developed a modular architecture, to offer those options most ordered on a Built-To-Order program. This has enabled us to offer you a customized product with a reduced lead time. Our goal is to optimize our response to meet your mission critical application needs.

The RediStart CFMVRMX series with MX3 technol-ogy is a fully integrated, programmable family of Class E2 load break/combination solid state start-ers. This integrated design includes control and power electronics, bypass and isolation contactors that reduce maintenance and operating costs when compared to other methods.

Key Advantages:

Protect machinery from failure and excessive maintenance caused by mechanical shock during starting or stopping. The RediStart MVRMX provides smooth, stepless acceleration and controlled deceleration.

Protect electrical systems from disruptive voltage drops and power outages caused by motor locked rotor inrush current. The RediStart MVRMX starter precisely controls the current ramp during start up.

Protect mission critical motors from failure or un-scheduled outages caused by machine or electrical system faults. The RediStart MVRMX starter pro-vides complete, high performance, coordinated line monitoring, motor control and protection.
