Meidensha 5 Tier Medium Voltage Combination Starter

Manufacturer: Meidensha Corporation

Features

The flat design VMC allows a maximum of 5 stacking, reducing the footprint by approximately 60%. Medium voltage live parts are isolated with an earthed metal and a shutter made of insulating material. The insulating mold partition walls ensure vertical busbars are isolated between phases and betwen phases and earth. The multi-functional digital relay and wide range CT require only parameter adjustments for different loads, capacities and starting methods, eliminating the need for replacing CTs.
Small footprint
Safe and reliable
Flexible applications

Applications and Solutions

The small footprint allows installation in a confined space that is too small for similar products
