Feature → Business Impact → Application: The 300 A amperage rating provides precise overload protection for demanding loads, reducing fuse changes and unplanned downtime in manufacturing lines. This translates to improved line uptime and lower maintenance costs when deployed in LG-frame MCCB configurations for three-phase power feeds. Application: motor feeders and distribution panels in medium-sized control systems benefit from stable protection and predictable trip behavior. Feature → Business Impact → Application: Three-pole design in the LG frame enables true three-phase protection, improving voltage balance and selectivity. Application: panel boards and equipment racks in packaging, material handling, and process industries gain enhanced coordination with other protective devices. Feature → Business Impact → Application: Trip Type T185 with fixed thermal and adjustable magnetic trip enables tailored protection curves, delivering rapid fault clearing without unnecessary outages. Application: critical conveyors and CNC machinery where precise coordination reduces downtime and increases throughput. Feature → Business Impact → Application: High interrupt ratings—200 kAIC at 240 Vac, 150 kAIC at 480 Vac, 65 kAIC at 600 Vac—offer robust fault tolerance in spaces with elevated fault currents. Application: heavy industry and high-energy environments where short-circuit resilience is essential. Feature → Business Impact → Application: Without terminals, field wiring flexibility requires compatible lugs or terminals, supporting adaptable installation in retrofit projects. Application: retrofit and new builds where terminal options and LG-frame compatibility streamline procurement and assembly. Feature → Business Impact → Application: 80% rated design supports efficient thermal performance with steady protection under partial-load conditions. Application: energy-efficient panel design in OEM machinery and process lines. Certifications and compliance—UL Listed, IEC Rated, CSA Certified, CE Marked—help meet global safety standards and simplify cross-border sourcing for multi-site deployments. Application: global manufacturers coordinating worldwide installations with consistent protection standards.
