Eaton E2NM310W Mining MCCB - 25 kAIC at 1000 Vac

The E2NM310W is a three-pole, N-frame mining molded case circuit breaker rated for 1000 A, with a magnetic trip range of 1250–5000 A and an interrupt rating of 25 kAIC at 1000 Vac. Feature → Business Impact → Application: Electronic trip type (Digitrip) enables selective tripping and improved coordination, reducing nuisance trips and minimizing fault energy exposure, which translates to longer equipment life and fewer unplanned outages in underground or surface mining plants. This unit supports 1000Y/577 Vac and 250 Vdc, providing flexible multi‑source protection for drive systems, feeders, and distribution panels in harsh mining environments. The compact N-frame, three-pole design, and a 5.5 in depth with 8.25 in height and width streamline panel layout and retrofit projects, enabling easier installation in compact switchgear and service centers. With a 45 lb weight and a 1000 A amperage rating, it delivers robust protection without excessive footprint. Warranty is defined by Eaton’s policy 25-000 (one year from installation or 18 months from shipment), offering predictable support for maintenance cycles. For compatibility, the breaker is listed as a specialty complete unit, without terminals, facilitating field configurability and custom terminal solutions as needed. The product’s mining-class construction supports operation in demanding underground environments, while its 25 kAIC rating ensures resilience against high-energy faults common in mining applications. Overall, the E2NM310W combines proven protection with industry-specific features to support uptime, safety, and cost efficiency in mining power distribution.
