FAQs
For underground installations, mount the E2LEM3600M2WU66 in a compliant MCCB enclosure with appropriate clearance for heat dissipation. The unit is a three-pole, L-frame E2LEM with no terminals pre-installed, so plan for field wiring of conductors and compatible accessories. Ensure correct undervoltage release wiring and secure mounting to minimize vibration and fault propagation in harsh environments.
The E2LEM3600M2WU66 uses a T165 trip type with a magnetic trip range of 1000–4000 A. This combination provides fast, selective fault isolation for high-current mining feeders while avoiding nuisance trips during normal startup transients. It supports reliable protection for heavy loads such as crushers and conveyors in variable mine loads.
Yes. The device is rated for 1000Y/577 Vac and 250 Vdc, making it suitable for mixed AC/DC control environments typical in mining plants. Its UL Listed, IEC Rated, and CSA Certified status further assures regulatory compliance and compatibility with standard mining electrical architectures.
The breaker is UL Listed, CSA Certified, and IEC Rated. These certifications validate safety, performance, and interoperability across global mining sites, simplifying supplier qualification, audit readiness, and cross-border procurement for multi-site operations.
