Eaton MDL3800A05S01 MCCB - UL Listed

With an 800 A amperage rating in the MDL frame, the MDL3800A05S01 provides robust upstream protection for feeders and motor loads in demanding industrial environments. The three-pole design and Series C architecture enable reliable coordination with standard panel buses while keeping installation compact in tight electrical rooms. Rated at 600 Vac and 250 Vdc, it supports both AC and DC protection requirements for mixed plant circuits. Fixed thermal and fixed magnetic trip mechanisms deliver precise fault detection across a wide operating window, reducing nuisance trips while preserving equipment downtime during faults. The option for a shunt trip (12-24 Vac/dc, left side) and a 1A-1B auxiliary contact (right side) provides remote signaling and enhanced control integration with modern PLCs and motor controllers. The MDL3800A05S01 is rated for up to 50 kAIC at 480 Vac and 65 kAIC at 240 Vac, delivering high-fault current withstand for large motors and feeder circuits. Its MDL frame and complete breaker construction simplify panel integration and spare-part compatibility, while the Series C design supports a broad range of Eaton accessories and plug-in options. UL Listed certification confirms compliance with recognized safety standards, easing procurement and panel certification processes. The component’s compact footprint, unified MDL frame, and compatibility with StrandAble terminals and other Eaton accessories reduce installation time and labor costs in panel shops. Engineers gain confidence from documented performance, including 50/60 Hz operation and wide voltage range. Applications span motor control centers, feeders, and process equipment in manufacturing and processing facilities. By selecting the MDL3800A05S01, procurement gains a high-availability MCCB with predictable trip behavior, scalable accessories, and a familiar Eaton ecosystem—supporting improved uptime, easier maintenance, and simplified spare-part management across projects.
