Eaton E2M3800MXWU66 Mining MCCB - UL Listed

High current capacity and three-pole construction deliver reliable protection for mining feeders and motors. The 800 A rating supports large drive systems while the M-frame housing accommodates rugged enclosures and clean wiring. In typical mining panels, this combination reduces nuisance trips and improves coordination with upstream breakers, translating to fewer unplanned outages and lower maintenance costs. Magnetic trip range of 2000–4000 A, with an interchangeable magnetic trip, lets you tailor protection to your exact fault currents without stocking multiple device types. This flexibility speeds field upgrades and minimizes spare parts inventory while preserving fast, predictable tripping under short-circuit conditions. Operators trust the E2M for consistent performance across a range of mine ratings and system geometries. DC and AC protection are supported by robust interrupt ratings: 65 kAIC at 240 Vac, 35 kAIC at 480 Vac, 25 kAIC at 600 Vac, and 22 kAIC at 250 Vdc. The 250 Vdc rating makes it suitable for DC control buses and high-current loads, while the AC ratings cover conveyors and motors. These specs enable safer shutdown sequences and improved selectivity in multi-bus architectures. Undervoltage release at 120 Vac with mining rear mounting and left pigtail adds control-circuit protection to your sequencing logic. This feature helps prevent unintended tripping during voltage sags and aligns with common mining control schemes. It also supports safer lockout-tagout practices by ensuring control circuits reflect outage conditions before breakers trip. Installation flexibility is supported by the unit being specified as without terminals, enabling you to choose compatible lugs or cable accessories that match your panel design. Compatibility with Eaton E2 accessories and knowledge of the E2 catalog entries streamline sourcing and substitution in retrofit projects, reducing downtime during panel modernization. Warranty and certifications add total-cost-of-ownership value: UL Listed and CSA Certified provide regulatory assurance, while a one-year warranty (or eighteen months from shipment) offers risk protection for early field deployments. For mining operators seeking dependable protection with predictable maintenance, the E2M3800MXWU66 offers a proven, long-term solution.
