Selling Policy 25-000 - Distribution and Control Products and Services
The LG3600S03 features a 600 A amperage rating and a 600 Vac voltage rating within an L-frame, Series C three-pole design. This configuration enables reliable protection for large motor loads and engine-generator sets, delivering measurable uptime improvements and safer start-up sequences in MCCs and critical power paths. The fixed thermal and magnetic trips (T186) provide precise overcurrent protection, reducing nuisance trips and protecting both equipment and personnel in manufacturing lines and process environments. A remote shunt-trip input (12-24 Vac/dc, left-side) adds an additional layer of safety, allowing emergency shutdowns and coordinated protection with central control systems. Generator compatibility is a core strength, with generator ratings up to 542 kVA at 600 Vac, supporting diverse gensets used in data centers, manufacturing facilities, and utility-scale applications. Line and load terminals simplify wiring and retrofit, while the Series C packaging and compact dimensions ease installation in crowded electrical rooms. The product’s weight of 16 lb and dimensions of 5.48 in on each axis help with precise rack and panel planning, transport, and mounting. Proven certifications (UL Listed, CSA, IEC Rated) reinforce compliance and peace of mind for regulated environments. In short, LG3600S03 is a dependable platform for motor protection, generator protection, and distribution reliability across industrial facilities.
