Description
Engineered for commercial power systems, the LA3600NW operates strictly as a molded case switch. It provides manual load isolation with a high-magnetic trip designed exclusively for internal self-protection. This three-pole disconnect mounts into older Westinghouse and Cutler-Hammer switchboards. Serving as a reliable L-Frame replacement, it restores functionality and is cross-referenced with the LD3600K. Handling 600A up to 600VAC, it ensures safe maintenance without overload protection.Specifications
