Understanding circuit breaker design and operation to improve safety and reliability in underground mining
Interchangeable magnetic trip enables tuning fault protection in the field without swapping components, reducing maintenance downtime and spare-part needs for mining plants that frequently reconfigure conveyors or motors. This translates to faster turnarounds and consistent protection as mine equipment evolves. The breaker’s high interrupt rating—35 kAIC at 480 Vac, 25 kAIC at 600 Vac, and 65 kAIC at 240 Vac—provides a generous safety margin for fault currents in demanding mining feeds, limiting arc flash exposure and protecting cables and motors. An undervoltage release option (110-127 Vac, same side with left pigtail) supports safer, auto-trip behavior during voltage sag events, minimizing equipment stalls. With a three-pole L-frame design and a complete breaker, installation aligns with standard mining MCCBs, improving panel integration and serviceability. Terminals are not included by default, offering installation flexibility to match customer bus-bar configurations. Certifications UL Listed, IEC Rated, CSA Certified reinforce compliance across global mine sites, while the 400 A rating suits medium-to-large mining feeders and motor circuits. This combination reduces commissioning time, extends asset life, and lowers total cost of ownership in underground and surface mining environments.

FAQs
The E2LEM3400MWU17 is a three-pole, L-frame mining MCCB designed for standard mining switchgear and motor control centers. It ships as a complete breaker option (without terminals) and supports field-assembled terminations to align with customer bus-bar configurations, simplifying integration in underground and surface mining installations.
It is UL Listed, IEC Rated, and CSA Certified, signifying established safety and performance across North American and international mining environments. These certifications help ensure regulatory compliance, interoperability with other certified components, and confidence in safety margins during inspections and audits.
Key specs include a 400 A amperage rating, voltage ratings of 1000Y/577 Vac and 250 Vdc, a T205 trip type, and a three-pole design. Interruption ratings reach 35 kAIC at 480 Vac, 25 kAIC at 600 Vac, with other values for DC and alternative AC voltages to cover diverse mining scenarios.
The undervoltage release (110-127 Vac with left-side pigtail) enables automatic tripping during undervoltage conditions. This reduces the risk of stalled equipment, protects motors from low-voltage faults, and enhances overall safety in remote mining environments with variable power quality.
Its complete breaker construction, compatible frame L, and non-terminal configuration provide flexible integration with existing switchgear and bus work. The rugged build, combined with UL/IEC/CSA certifications, supports lower maintenance costs, easier spares planning, and longer asset life in both underground and open-pit mining operations.
