FAQs
The E2LE3600WU66 is a three-pole L-frame mining MCCB marked for complete breaker installations without terminals. Ensure mounting within compatible mining panels, connect the undervoltage release wiring (120 Vac mining rear with left pigtail), and integrate with the panel bus and mounting hardware specified for L-frame MCCBs. Verify clearance, torque requirements per the panel guidelines, and confirm the device is wired for 600 Vac / 250 Vdc operation with appropriate protective accessories.
Key ratings include a 600 A amperage rating, 600 Vac / 250 Vdc voltage rating, and a three-pole design with an interchangeable thermal-magnetic trip (T207). The interrupt rating is substantial across multiple voltages, with 65 kAIC at 240 Vac and up to 22 kAIC at 250 Vdc, supporting high fault currents typical in mining installations.
Yes. It is designed for mining use with a mining class designation, UL Listed and CSA Certified to meet safety and performance requirements in underground and harsh environments. It also supports 120 Vac mining rear with left pigtail undervoltage release, aiding reliable operation and signaling in restricted access areas.
The breaker carries UL Listed and CSA Certified marks, indicating compliance with recognized safety and performance standards. These certifications help satisfy procurement and regulatory requirements for mining equipment, support safe operation in regulated workflows, and simplify supplier qualification and MSHA-related documentation when selecting protection devices.
Plan for a 600 A, 600 Vac / 250 Vdc protection target and ensure panel compatibility with L-frame, three-pole complete breakers. Account for the absence of terminal connections on the device itself, add appropriate terminals if required, and confirm available undervoltage release wiring. The unit supports high fault current scenarios and can improve maintenance intervals when coordinated with upstream protection schemes.
