Interchangeable thermal-magnetic trip is a core feature that enables precise protection settings without replacing the breaker, reducing field service time and improving uptime for critical mining circuits. The business impact is fewer nuisance trips and lower maintenance cost, which translates to higher equipment availability on conveyors and mining shovels. This aligns with applications in underground mining where load profiles vary and quick protection adjustments are essential. The device’s 800 A at 250 Vdc rating delivers robust protection for high-current DC distribution common in miner power systems, translating into improved continuity for charging stations and vehicle fleets. In practice, this means fewer thermal runaways and better long-term component life, supporting a lower total cost of ownership for underground operations. The three-pole E2M with an M-frame complete breaker design simplifies mounting and wiring in crowded control panels, enabling faster installation and easier future upgrades. With terminals configured as without terminals and an undervoltage release of 120 Vac mining rear with left pigtail, panel builders gain flexibility to route wiring efficiently and safeguard control logic against undervoltage conditions. The interrupt ratings—65 kAIC at 240 Vac and 22–35 kAIC at other voltages—provide headroom for fault currents typical in mining substations, improving fault-clearing reliability and reducing system-wide downstream damage. Certifications and warranty support further de-risk modernization projects, giving maintenance teams confidence in long-term compliance and service support for mining fleets. Overall, the E2M3800WU66 combines rugged construction with installation efficiency, delivering measurable uptime gains and a resilient protection solution for mining environments.

FAQs

The E2M3800WU66 uses an M-frame, three-pole design with a complete breaker assembly. It ships without terminals, allowing flexible wiring to suit panel layouts, and supports standard MCCB mounting rails for quick installation in mining control panels. The undervoltage release feature, 120 Vac mining rear with left pigtail, simplifies wiring and control integration in underground environments.
The device is rated for 800 A and 250 Vdc, with a T207 trip type. It provides a magnetic trip range of 2000–4000 A and an interrupt rating up to 65 kAIC at 240 Vac (and lower at higher voltages). These specs ensure reliable protection for high-current mining circuits and fast fault clearance in harsh conditions.
Yes. It is designed for mining applications with DC ratings (250 Vdc) and includes an undervoltage release (120 Vac mining rear with left pigtail) to guard control circuits against undervoltage conditions, enhancing overall protection for DC mining power systems and related equipment.
The unit is CSA Certified and UL Listed, confirming compliance with widely recognized safety and performance standards for mining electrical protection devices. These certifications help satisfy regulatory requirements for underground facilities and facilitate environmental and safety audits in mining operations.
The rugged mining design reduces unplanned outages and maintenance calls, improving equipment availability and uptime. Interchangeable trip elements simplify field adjustments, while a one-year warranty (or 18 months from shipment) provides financial protection during initial deployment, contributing to a favorable total cost of ownership in mining fleets.
