FAQs
The E2M3800MNW uses an MDL frame with a three-pole design and is supplied without terminals, streamlining field mounting in standard mining MCCB panels. Ensure panel space accommodates an 8.25 inch width and 8.25 inch height device, and verify mounting aligns with common DIN rail or bolted interfaces used in mining equipment. The 800 A rating should be matched to your feeder and motor protection strategy, and accessory compatibility should be checked for future expansion.
Key specs include an 800 A amperage rating at 250 Vdc, three-pole configuration in the MDL frame, and a magnetic trip range of 1500–3000 A with T205 trip type. The interrupt ratings are 25 kAIC at 600 Vac, 22 kAIC at 250 Vdc, plus additional ratings at other voltages (65 kAIC at 240 Vac and 35 kAIC at 480 Vac). Certifications include UL Listed and CSA Certified.
