FAQs
The E2MM3800W ships without terminals, so plan for compatible field-installed terminal hardware per your panel design. Ensure proper mounting in the M-frame, confirm enclosure clearance, and align with your bus layout. Use Eaton-recommended terminal accessories and follow the device’s three-pole arrangement to maintain safe separation and reliable protection for high‑current mining circuits.
Key specs include an 800 A amperage rating, voltage ratings of 1000Y/577 Vac and 250 Vdc, a three-pole configuration, and a magnetic trip range of 2000–4000 A. The unit is designed as a mining specialty complete breaker with an 18 kAIC at 1000Y/577 Vac, 22 kAIC at 250 Vdc, and higher ratings at other voltages, supporting robust short-circuit protection.
Yes. Classified as Mining with an M-frame complete breaker, the E2MM3800W is purpose-built for mining power distribution. Its three-pole design, 800 A rating, and wide voltage operating windows, combined with a high interrupt rating and interchangeable trip, make it well suited for heavy-duty underground equipment, ore handling, and processing lines where uptime and safety are paramount.
Compliance and certification details are provided by the manufacturer. For the E2MM3800W, verify the latest SIL, CE, IP ratings, and other regulatory markings directly with Eaton. Eaton also supplies product aids and datasheets to assist with regulatory submissions and safety documentation, ensuring alignment with your mining site’s safety and environmental requirements.
