FAQs
The E2LM3450W uses an L-frame, three-pole configuration and is provided without terminals, so field-installation lugs or bus connections are required. Ensure enclosure compatibility, proper clearances, and torque specifications per Eaton guidance. Verify the control wiring scheme matches the T165 trip type to avoid nuisance trips and ensure safe operation in mining panels.
Key specs include a 450 A amperage rating, voltage rating of 1000Y/577 Vac and 250 Vdc, a trip type of T165, and a magnetic trip range of 2250–4500 A. The device is a three-pole, L-frame mining MCCB with an interrupt rating up to 100 kAIC at 240 Vac and other values at various voltages, delivering robust fault protection.
Yes. Classified as a Mining-grade MCCB with an L-frame design and three-pole configuration, it is engineered for rugged underground and surface mining environments. Its high interrupt rating and durable construction support reliable protection of feeders and motors in challenging conditions.
Certification details are provided by the manufacturer. The datasheet and service literature indicate to contact Eaton for specific SIL, CE, and IP ratings, as applicable to your region and project requirements. Your procurement team should request the exact certifications needed to meet regulatory or customer standards.
The E2LM3450W supports reduced downtime through fast and reliable tripping, improved motor protection, and streamlined maintenance with standard Eaton service guidance. A one-year warranty (or 18 months from shipment) helps manage lifecycle costs, while the rugged design minimizes replacement cycles in harsh mining environments.
