Feature: 600 A bus rating with a 10 kAIC interrupt rating provides robust fault protection and scalable distribution for mid-size facilities. This enables designers to run larger feeders without multiple enclosures, reducing panel count and installation time. Application: ideal for manufacturing lines, data centers, and process rooms needing reliable power with minimal downtime. Business Impact: lowers risk of fuse trips and downtime, improving overall plant uptime and maintenance planning. Keywords: 600 A bus rating, 10 kAIC, fault protection, industrial power distribution. Feature: Bussed gutter and termination cabinet design with aluminum bussing streamlines bus bar routing and termination. Business Impact: minimizes field wiring, shortens commissioning, and improves thermal performance through centralized conductor paths. Application: suitable for switchgear access and meter mounting areas in new builds. Keywords: bussed gutters, termination cabinets, aluminum bussing, centralized conductors. Feature: Line lug size #4–600 MCM and load lug size 5/16 inch support a wide range of feeders and lugs, eliminating adapters. Business Impact: lowers inventory, accelerates termination, and reduces error-prone field work. Application: supports 1Ø/3W configurations with (2) 1/0–250 MCM cables per cabinet. Keywords: lug sizing, #4–600 MCM, 5/16 inch, 1Ø/3W, field termination. Feature: Construction and finish combine durability with protection. The galvanized steel body and ANSI 61 gray paint finish offer corrosion resistance and weather resilience. UL Listed and NEMA 3R enclosure protection support reliable operation across indoor and outdoor installations. Application: ideal for utility rooms, outdoor meter racks, and harsh industrial environments. Keywords: UL Listed, NEMA 3R, ANSI 61 gray, galvanized steel, enclosure protection. Feature: Surface-mount design with 6 positions and defined mounting holes enables quick, secure installation. Dimensions and weight (6 in depth, 22 in height, 42.75 in width, ~71 lb) support straightforward handling and space planning. Application: fits compact footprints in retrofit projects and new builds with demanding space constraints. Keywords: surface mount, mounting holes, load lug compatibility, space efficiency.
