Product description
Shipping

The Eaton MWI8104LEA is a robust 1000A, 4-pole air circuit breaker designed for reliable protection and switching in low-voltage power distribution systems across industrial and commercial facilities. Built for endurance, it handles heavy-start loads and fault conditions while safeguarding personnel and downstream equipment.

  • High-capacity, 4-pole design: protects all three phases plus neutral, ideal for balanced, safe shutdowns in three-phase systems.
  • 1000A current rating: suitable for main incoming feeders and switchboards in mid- to large-scale installations.
  • Adjustable trip settings: enables precise coordination with downstream protection devices, reducing nuisance trips and ensuring selective tripping during faults.
  • Air circuit breaker construction: rugged, easy to reset, and suited for demanding industrial environments where reliability matters.
  • Low-voltage protection: part of a comprehensive power distribution strategy, protecting feeders, panels, and critical circuits in industrial and commercial facilities.
  • High interruption capacity: designed to clear faults quickly, minimizing downtime and protecting valuable equipment.

Where to use: - Main incoming feeders in switchboards for factories, campuses, and large commercial facilities. - Critical distribution points where coordinated protection is essential for uptime. - Retrofit and new-build projects needing a scalable, robust 4-pole breaker with adjustable trip curves.

Why choose the MWI8104LEA over simpler breakers? Because it combines substantial current handling with precise trip coordination, a solid air-quench mechanism, and a form factor that fits standard low-voltage switchgear while delivering dependable protection for demanding loads. It’s purpose-built for environments where reliability and uptime are non-negotiable, and where you must protect both equipment and personnel from electrical faults.
