Eaton LDB2450W Molded Case Circuit Breaker - UL 489

The 450 A ampacity and two-pole, L-frame construction deliver scalable protection for heavy feeders while maintaining a compact footprint; this translates to reduced panel space and easier integration into existing cabinets. With a fixed thermal-magnetic trip type (T186), fault clearing is fast and deterministic, lowering the risk of arc energy damage and enabling safer maintenance windows. The Series C complete breaker design, combined with a 50/60 Hz frequency rating and interruption capabilities of 65 kAIC at 240 Vac and 35 kAIC at 480 Vac, supports wide-range industrial applications from packaging lines to process controls, improving reliability and compliance across diverse installations. The product is specified as without terminals, which simplifies field wiring when using compatible lug or busbar solutions and ensures clean, vibration-resistant installation in rugged environments. UL 489 certification and the documented UL-listed 100%-rated performance provide confidence in safety, while the 8.25 in depth and 8.25 in height/width footprint aligns with standard Series C MCCB layouts, enabling efficient procurement and lifecycle management. The LDB2450W also benefits from Eaton’s warranty policy, supporting long-term maintenance planning and reducing total cost of ownership for panel builders and plant engineers. Compatibility with the Series C ecosystem and the fixed trip mechanism helps streamline spare parts management and reduces engineering lead times for panel upgrades and new builds.
