Quick Summary

The Eaton E2N310WA06U66 is a mining MCCB designed to protect large electrical systems in underground mining. Operators often face nuisance trips, limited diagnostics, and costly downtime when protection schemes drift out of coordination. UL Listed certification ensures safety compliance, while the N-frame mining design and robust interrupt ratings deliver rugged, field-proven performance; regional CE and IP considerations should be validated for your installation. This model combines an electronic LI trip with a rear 1A-1B auxiliary switch to support safer shutdowns and clearer fault signaling. With a compact 16.5 in length, 9 in width and height, and a 46 lb weight, it fits demanding mining panels and supports scalable protection for 600 Vac feeders.

High current rating and magnetic trip range enable precise protection for large mining feeders. The device specifies 1000 A continuous amperage and a magnetic trip range of 1250–5000 A, with up to 65 kAIC at 240 V, 50 kAIC at 480 V, and 25 kAIC at 600 V. This combination supports selective coordination in high-power underground installations and reduces the risk of nuisance trips during startup. Electronic LI trip provides accurate coordination and faster fault clearance, improving system reliability and maintenance planning. In mining environments, this translates to shorter downtime during faults and improved protection of pumps, conveyors, and fans. Rear-mounted 1A-1B auxiliary switch with right pigtail enables remote signaling and control integration with MCC panels and SCADA, reducing wiring complexity and supporting easier fault tracing. Undervoltage release 120 Vac rear with left pigtail adds a safety layer for automatic tripping during undervoltage conditions, enhancing safety in remote operations and lockout/tagout procedures. The rugged N-frame mining design, UL Listed, and a compact footprint offer installation flexibility in constrained spaces while ensuring safety compliance. Terminals are not included; field-installed lugs or bus options give you flexibility to match existing MCCB buswork and facilitate quick replacements, improving deployment timelines and total cost of ownership.
