Eaton LDCB3450 Molded Case Circuit Breaker - UL 489

450 A amperage rating enables higher load capacity for demanding feeders, reducing the need for oversized gear and simplifying panel design. This improves efficiency by allowing closer load matching and fewer upstream protection devices, which lowers equipment footprint and total cost of ownership. Ideal for service entrances, distribution panels, and MCC feeders in manufacturing lines that run near peak demand. Interrupt ratings of 200 kAIC at 240 Vac and 100 kAIC at 480 Vac translate to robust short-circuit protection across a wide voltage range. The business impact is improved uptime and reduced risk of collateral damage during fault events. Field installations in data centers, processing plants, and automated lines benefit from reliable coordination with upstream breakers. Fixed thermal and fixed magnetic trip (T186) provide predictable trip curves and swift fault isolation, supporting safe start-up sequencing and coordination with motor protection schemes, minimizing nuisance trips during inrush and load swings. Applications include motor control centers and panel boards with mixed motor loads. L-frame, Three-pole design with aluminum line/load terminals and 50/60 Hz operation offers durable, corrosion-resistant wiring and straightforward installation. The business impact is easier wiring, faster commissioning, and long-term reliability in harsh environments. Suitable for standard building electrical systems, industrial plants, and process lines requiring consistent performance.
