SOFT STARTERS<br />
MVX Soft Starter<br />
Overview<br />
The MVX provides compact and robust soft start solutions for control of medium voltage motors. MVX soft starters<br />
provide a complete range of motor and system protection features and have been designed for reliable performance<br />
in the most demanding installation situations.<br />
Each MVX soft starter comprises:<br />
a Phase Cassette<br />
a Controller module<br />
The Phase Cassette and Controller module are supplied as a pair and share the same serial number. Care should be<br />
taken during installation to ensure the correct Controller and Phase Cassette are used together.<br />
Feature List<br />
NOTE<br />
Fibre-optic cables are only supplied in IP00 variants of the MVX soft starter. In all other MVX soft<br />
starters, this is part of the main assembly.<br />
