High amperage rating of 1200 A enables a single switch to protect large feeders, reducing the need for multiple devices and simplifying protection coordination. Fewer components translate to lower maintenance costs, tighter spare parts inventories, and faster fault isolation in critical lines such as motor feeders and processing lines. The fusible with neutral configuration supports proper neutral return paths, improving system reliability and fault clearing without introducing unbalanced currents that can damage equipment. This 3-wire 240V design simplifies field wiring and panel routing, reducing install time and increasing installer confidence with clear wiring diagrams. The NEMA 3R, painted galvanized steel enclosure provides weather and corrosion resistance for outdoor or damp environments, extending service life and lowering outdoor maintenance requirements. UL Listed and NEC 230.62(C) compliant barrier offer regulatory assurance and safer maintenance routines, helping audits and safety programs. Large conductor capacity—up to four #1/0 to four 750 kcmil aluminum conductors—facilitates future upgrades and minimizes rework for evolving plant needs.
