FAQs
This 3-pole, N-frame mining MCCB is designed for underground mining electrical systems, including distribution panels and feeder circuits. With a 600 A rating and 25 kAIC interrupt capability at 1000 Vac, it handles high short-circuit currents while preserving equipment. The 1000Y/577 Vac and 250 Vdc ratings support mixed AC and DC applications common in mining equipment suites.
Key specs include a 600 A amperage rating, 25 kAIC interrupt rating at 1000 Vac, voltage ratings of 1000Y/577 Vac and 250 Vdc, a three-pole configuration, and the T165 trip type. It supports 120 Vac mining rear undervoltage release with left pigtail and a rear 1A-1B auxiliary with right pigtail for remote signaling.
The electronic LI trip provides fast, precise fault detection with predictable tripping curves, reducing nuisance trips and protecting motors, conveyors, and feeders. This improves safety by minimizing fault exposure and helps operators maintain production schedules by shortening downtime after faults. The feature is particularly valuable in harsh underground environments where reliable protection matters most.
The E2NM3600WA06U66 uses an N-frame, three-pole design with no terminals included, which allows customer-specified terminations. Its compact 8.25 in footprint and 45 lb weight help with panel density in tight mining switchgear. Rear-mounted accessories (1A-1B rear with right pigtail and undervoltage 120 Vac mining rear with left pigtail) support flexible wiring and remote control options.
Product documentation and mining-specific guidance are available through Eaton’s downloadable materials, including mining-focused brochures, MSHA policy letters, and E2 MCCB datasheets. Always verify region-specific certifications (SIL, CE, IP) from the manufacturer to ensure site compliance and to align with maintenance and replacement planning.
