Eaton MDLB3350 Molded Case Circuit Breaker - UL Listed

Feature → Business Impact → Application: The MDLB3350 offers a 350 A amperage rating, enabling robust protection for heavy feeders and high-demand loads, which translates to reduced fuse wear, fewer nuisance trips, and lower maintenance costs in motor control centers. This supports uptime in packaging lines and metalworking machinery where consistent protection is critical. Feature → Business Impact → Application: Fixed thermal and fixed magnetic trip type provides predictable, rule-based protection with fast fault clearance, improving selectivity and reducing collateral outages in multi-device panels. This is ideal for machine assemblies where clear coordination between devices prevents cascading trips and short downtime. Feature → Business Impact → Application: Three-pole design with Series C MDL frame ensures reliable three-phase protection, simplifying wiring and enhancing safety in compact automation cabinets. It enables straightforward installation and consistent performance in new builds or upgrades for control panels. Feature → Business Impact → Application: 50 kAIC at 480 Vac and 65 kAIC at 240 Vac interrupt ratings deliver high fault current withstand, increasing crew safety and equipment protection in industrial facilities with heavy loads and short-circuit potential. Feature → Business Impact → Application: UL Listed certification and extensive Eaton documentation (timing curves, application notes) support regulatory compliance, reducing engineering time and accelerating approvals for plant modernization. Feature → Business Impact → Application: 50/60 Hz compatibility and complete breaker specification (MDLB, MDL frame, Series C) enable fast integration with existing electrical infrastructure across facilities, ensuring consistent performance from one panel to another and lowering training requirements for maintenance staff.
