FAQs

For the E2NM3800MW, plan for a three-pole, N-frame installation with space for the without-terminal configuration. Ensure proper enclosure sizing, correct bus connections, and compliant wiring practices. Use compatible Eaton accessories and follow the specified torque values to maintain magnetic trip accuracy and prevent nuisance trips in high-current mining loads.
The device is rated for 800 A with a voltage rating of 1000Y/577 Vac and 250 Vdc. It protects heavy mining drives, feeders, and motor circuits by interrupting fault currents up to 25 kAIC, providing reliable protection for both AC and DC-powered mining equipment under typical underground and surface mine conditions.
Yes. The E2NM3800MW is designed as a mining-class, three-pole MCCB with a high interrupt rating and robust construction suitable for underground environments. Its magnetic trip (T205) and N-frame format support reliable protection coordination in underground switchgear while meeting industry practices for mining applications.
Key mining industry considerations include safety and environmental standards such as CE marking for safety, IP-rated protection for dust and water ingress, and MSHA guidance for underground performance. While exact certifications should be confirmed with Eaton, these standards are commonly referenced in mining MCCB selections and service documentation.
Routine maintenance includes periodic inspection of the magnetic trip mechanism, verification of torque on terminal connections, and validation of insulation integrity. Eaton’s service literature and mining case studies highlight the importance of using genuine components, performing regular tests, and coordinating with authorized service centers to minimize downtime and extend breaker life.
