ROTOCON ERG-300 Model Specifications

The high-current ERG-Series provides the perfect ground to meet the most demanding applications. The flexible design offers an abundance of exciting options and mounting variations. ROTOCON ERG-Series can be used for the positive (plus) or the negative (ground) end of all circuits without any difference in performance. The product line is also strategically engineered to accommodate weight of cables and work pieces that have historically presented challenges throughout the industry.

Suitable for all demanding environments, including welding, electro-plating, cutting, and other high current industrial applications, the ERG-Series is designed to withstand 100% duty cycles in continuous manufacturing and production processes. The brush-free design eliminates all issues such as maintaining brush contact, application of conductive greases, and the elevated contact resistance associated with conventional brushed rotary grounds
