FAQs
The E2LEM3600MWU66 uses a three-pole L-frame complete breaker design, with dimensions of 10.75 in length, 8.25 in height, and 4.06 in width. It is configured without terminals, requiring appropriate rear connections or field retrofits per your enclosure. Verify panel clearance, torque settings per Eaton datasheets, and ensure the undervoltage release is wired to 120 Vac rear with left pigtail for enhanced remote tripping reliability. Always consult the product spec sheets for exact installation torque and terminal options.
Key interrupt ratings include 35 kAIC at 480 Vac, 10 kAIC at 1000Y/577 Vac, 65 kAIC at 240 Vac, 22 kAIC at 250 Vdc, and 25 kAIC at 600 Vac. The trip type is T165, and the unit integrates a Digitrip 310+ electronic trip unit for precise, electronic protection. The amperage range is 500-2500 A with a normal 600 A rating, enabling flexible protection scenarios in mining applications.
Yes. The E2LEM3600MWU66 is designed for mining service, featuring forged ruggedness, mining-class classification, and UL Listed/CSA Certified marks. Its 120 Vac rear undervoltage release and left-pigtail configuration support safety interlocks and remote signaling, which are common requirements in underground mining control rooms and distribution panels. Always verify MSHA guidance and Eaton technical notes when qualifying equipment for underground deployments.
The device carries UL Listed, IEC Rated, and CSA Certified marks, aligning with common mining, electrical, and industrial safety standards. Eaton also provides related MSHA-related safety letters and product aids in its download section to support compliance demonstrations. In practice, these certifications facilitate procurement approvals, reduce site risk, and simplify cross-border specifications for global mining sites.
Warranty terms state one year from installation or eighteen months from shipment, whichever occurs first, which helps manage early-life costs. Eaton offers service center support, replacement parts, and documented technical comparisons (Digitrip 310+ vs. 310) to justify maintenance intervals and.troubleshooting. The combination of high interrupt reliability, minimal terminal requirements, and durable construction translates to lower downtime and improved return on investment in mining operations.
