Performance and Features

The Power of Performance
with the Features you need…

Expect peak performance from your critical medium voltage equipment when your motors are protected and controlled by Motortronics MVC Plus Series soft starters.



Designed for:

  • Heavy loads
  • Tough environments
  • Any power conditions
  • Reactor-less operationReactor less operation
In an unpredictable world the MVC Plus Series protects both your motor and your load…

  • Motor and starter protection is taken to a new level by combining a high-end motor protection relay with a heavy duty solid state starter.
  • Flexible control features and selectable ramping profiles to match any application… no need to compromise performance.
  • High level circuit isolation via fiber optics (standard on all units) for safety and power quality immunity.
  • Sealed NEMA 12 enclosures are standard equipment, not an expensive option.

Soft start & protect any AC motor

The MVC Plus Series starter is designed to start AC motors in any fixed speed application. It provides maximum protection with “True Thermal Modeling,” while allowing smooth, stepless control of acceleration and deceleration. The MVC Plus Series guarantees power control and protection for your most important assets.

Heavy-duty attitude

Highest rated power devices for maximum current carrying capacity. Rated at 500% for 60 seconds, the MVC Plus Series starter will never be the limiting factor in your application. Powerful sustained gate pulse insures reliable SCR firing without reactors (unlike “wimpy” pulse train designs that require a reactor to prevent SCR and motor damage).

Experience where it counts

With over 500,000 low voltage and medium voltage soft starters in operation, Motortronics has the application expertise you need. No other soft starter manufacturer takes this product more seriously or has as much experience
applying solid state starters. The MVC Plus Series is
the pinnacle of product development and is recognized by users and OEMS around the world as the best Medium Voltage Soft Starter on the market today.
