Interchangeable thermal-magnetic trip (T207) provides precise coordination and fast fault clearing, reducing nuisance trips and protecting expensive mining equipment. In practice, this improves uptime on ore conveyors and drill rigs by ensuring the right device trips first. Applications include main service disconnects and feeder protection in mining MCCBs. High current capability and robust interrupt rating mean it can safely interrupt in-rush and short-circuit events, with 350 A continuous rating and 10 kAIC at 1200 Vac. The three-pole L-frame ensures rock-solid mounting and thermal stability in harsh mine environments, translating to longer service life and reduced replacement costs in belt conveyors, hoists, and ongoing mining equipment. Shunt-trip readiness supports remote protection strategies for mine control rooms or motor control centers, with 12-24 Vac/dc left-side shunt for safer maintenance and control reliability. Terminals are not included, offering flexibility to match customer bus bars or field-terminated cables, reducing rework and installation time. Warranty and compliance are built in, with a one-year installation window (or 18 months from shipment) and CSA Certified UL Listed status, plus compact 13 in L Ă— 10 in W Ă— 7 in H dimensions and a 25 lb weight designed for reliable installation in mining panels.

FAQs

The E2LW3350W ships without terminals and is designed for field installation with customer-supplied terminations. Plan for compatible lugs or bus-bar connections to match the 13 in L Ă— 10 in W Ă— 7 in H footprint, and ensure the mounting supports the L-frame three-pole configuration. Verify insulation and torque specifications for field-terminated connections to maintain rated 10 kAIC interrupt capability.
Key specs include a 350 A amperage rating, 1200 Vac voltage rating, 10 kAIC interrupt rating at 1200 Vac, three-pole configuration, L-frame (Complete breaker), magnetic trip range 1750–3500 A, and trip type T207. It also supports a 12–24 Vac/dc shunt trip on the left side and ships without terminals, suitable for panel-mounted protection in mining environments.
Yes. This breaker is designed for mining service panels and control cabinets, featuring Mining class, 1200 Vac rating, 350 A rating, and 10 kAIC interrupt capability. Its rugged L-frame construction and T207 trip type are optimized for demanding underground mining protection and reliable motor and feeder protection in harsh environments.
The E2LW3350W is CSA Certified and UL Listed, ensuring compliance with major safety and performance standards relevant to mining and electrical protection equipment. These certifications support regulatory audits, vendor qualification, and installation in global mining facilities, reducing compliance risk and facilitating cross-border procurement.
Eaton offers a one-year warranty from installation or 18 months from shipment, whichever occurs first, covering manufacturing defects. Regular maintenance should focus on verifying shunt-trip operation, terminal integrity once installed, and periodic coordination checks with adjacent protection devices to maintain selective tripping and minimize downtime in mining operations.
