Part Number: E2LEM34002WA06U66
Quick Summary
Eaton E2LEM34002WA06U66 mining complete molded case circuit breaker protects mining feeders in harsh underground environments. Too often protection systems trip unpredictably or fail to coordinate with other mining equipment, causing costly downtime. UL Listed, IEC Rated, and CSA Certified ensure safety, regulatory compliance, and international interoperability for rugged mining installations. With a robust L-frame design and Electronic LI trip, this breaker supports reliable electrical protection strategies for mining equipment while enabling straightforward installation, back-check diagnostics, and low maintenance in remote sites. Manufacturers rely on consistent coordination with motor controllers and safety interlocks, which this unit delivers through its integrated trip logic and flexible mounting. Its compatibility with 120 Vac undervoltage release and rear pigtail configurations supports quick field retrofit and easier service at remote mining sites. This combination translates to reduced downtime, lower maintenance costs, and safer, more reliable mining operations.
