FAQs
The MPS8404MEAXX2C features drawout vertical mounting with motorized racking, which simplifies insertion and withdrawal of the breaker from the panel or switchgear while powered. This design reduces maintenance time, minimizes exposure to live components, and supports safer, faster swaps during routine servicing or fault isolation in industrial facilities.
This breaker carries UL Listed status and CSA Certified recognition, along with CE Marking and NEMA compliance. Additional certifications include ANSI and Lloyd's Register, with supporting approvals from KEMA, DNV GL, and ABS where applicable. These certifications support global deployment and regulatory alignment across diverse projects.
The MPS8404MEAXX2C is rated for 4000 A (current) with an 85 kA short-circuit rating, four-pole configuration, and a double standard frame. These ratings enable robust protection for large loads and motors, allow effective short-circuit withstand in switchgear, and support reliable operation in high-demand industrial environments.
The PXR20 LSIG electronic trip unit provides precise, programmable protection tailored to motor and process loads, improving selective coordination and fault isolation. This reduces nuisance tripping, enhances reliability for critical processes, and supports safer, more predictable protection schemes in complex power systems.
Eaton provides manuals, application notes, and coordination papers (such as zone selective interlocking papers) to support design and commissioning. Access to product datasheets, catalog papers, and support documents helps optimize protection schemes, drive down commissioning time, and improve long-term maintenance planning and ROI.
