EMX4e Soft Starter

Simple To Use

Smart does not have to mean complex. While the EMX4 offers more functionality than ever before, it has been designed to make your life easier.

Smart Card

The EMX4 Smart Card redefines the role of a soft starter. With the appropriate Smart Card installed the EMX4 is able to operate as an entire system controller.

Energy Efficiency

EMX4e is equipped with an internal bypass function to reduce operating costs. EMX4e starters are 99.5% efficient during run, produce no harmonics, and are the most energy efficient solution for fixed speed applications with variable load.

Mobile App

The AuCom Start Here app puts the tools you need to troubleshoot issues with starting and starter operation in the palm of your hand.
