Eaton E2M3800TMW E2 mining MCC trip unit - CSA/UL

Interchangeable magnetic trip in the E2M3800TMW enables retrofit versatility, reducing spare parts and simplifying field service. This directly lowers downtime costs for mining sites that upgrade aging MCCBs without full controller replacements. Applied to the M-frame, three-pole configuration, it pairs with existing E2 systems for consistent protection across drives and feeders. The 800 A amperage rating and 250 Vdc voltage rating address high-current DC drives used in conveyors and processing equipment. The magnetic trip range of 3000–6000 A provides selective coordination with upstream protection and fast fault clearance. In practice, this means improved system reliability and fewer nuisance trips during startup surges. The E2M3800TMW is built on an M-frame trip unit with the T205 trip type, aligning with mining-grade design standards. Its interrupt ratings—65 kAIC at 240 Vac, 35 kAIC at 480 Vac, 25 kAIC at 600 Vac, and 22 kAIC at 250 Vdc—safeguard both equipment and personnel. That diversity supports cross-site usage where different voltages and fault levels are encountered. CSA Certified and UL Listed markings reinforce compliance with industry and regulatory requirements. Mining class designation further confirms suitability for underground environments where dust, moisture, and shock are considerations. Engineers can rely on documented performance in Eaton’s mining MCCB portfolio to streamline procurement and service planning. Compact physical footprint and installability improve retrofit timelines, with dimensions of 4.06 in depth, 16 in height, and 8.25 in width. The product weighs about 3 lb, making on-site handling and panel integration straightforward. Compatibility with the broader E2 family ensures consistent protective behavior and easier spare parts management across sites.
