Quick Summary

Eaton Magnum low voltage power circuit breaker provides reliable overload protection for industrial power distribution. In mission-critical facilities, mis-coordination and slow fault clearing drive downtime, safety risks, and costly unplanned shutdowns. This model carries CE marking, UL listing, and CSA certification, with Lloyd's Register and ANSI approvals that support global compliance. Coupled with the Power Xpert Release (PXR) LSIG trip unit and fixed vertical mounting, it offers precise protection and straightforward integration into standard panels. With a 4000 A rating and an 85 kA interrupt capacity, it supports scalable distribution while reducing downtime and maintenance costs. Engineered for easy field retrofits and consistent coordination across feeders, it aligns with selective coordination papers and zone interlocking guidance.

Four-pole design with fixed vertical mounting improves fault isolation and panel space efficiency, enabling straightforward retrofits in existing switchgear. Business impact: faster commissioning, reduced panel depth constraints, and easier wiring. Application: suitable for large-distribution panels in manufacturing facilities that require robust four-pole protection and compact installation footprint. The PXR20 LSIG trip unit enhances protection coordination, reducing arc-flash exposure and enabling precise fault isolation. Business impact: safer maintenance windows and lower energy losses; Application: data centers and process lines with demanding uptime requirements. High interrupt capacity of 85 kA and current rating up to 4000 A support heavy-load feeders. Business impact: protects critical loads during faults, minimizes equipment damage, and improves system reliability; Application: main feeders and distribution bus sections in industrial plants. Compliance and certification coverage—UL Listed, CE Marked, CSA Certified, plus Lloyd's Register and ANSI approvals—deliver confidence for global projects. Business impact: simplifies procurement and speeds project sign-off; Application: multinational facilities with strict regulatory requirements. Zone selective interlocking and installation guidance are reinforced by Eaton’s application papers, enabling safer, faster, and more predictable protection strategies. Business impact: improved fault discrimination and reduced downtime across multi-feeder schemes; Application: complex switchgear where selective coordination is essential. Installation compatibility is reinforced by fixed-vertical-mount design and standard Magnum frames, enabling smoother integration with Power Xpert protection ecosystems. Business impact: reduced commissioning risk and streamlined panel-to-panel expansion; Application: retrofit projects that must align with existing Power Xpert components and protection plans.

FAQs

The MPS8404VEAXX2C uses a fixed vertical mounting compatible with Magnum PXR frames. Ensure panel space accommodates 16.3 in depth, 16.8 in height, and 44.1 in width as per catalog specifications. Follow the user manual mn013016en for torque values and wiring sequence, and verify coordination with adjacent breakers to maintain selective protection.
Key ratings include a 4000 A current rating and 85 kA interrupt capacity, four-pole configuration, and the PXR20 LSIG trip unit. It is designed for fixed vertical mounting in standard Magnum frames, with UL Listed, CE Marked, and CSA Certified approvals to support global compliance and reliable operation on demanding feeders.
Yes. The MPS8404VEAXX2C supports selective coordination when paired with compatible LSIG trip units and protection schemes. The PXR20 LSIG enables precise fault discrimination, while Eaton’s zone interlocking and coordination guidance papers help optimize protection across multi-feed distributions in manufacturing environments.
This breaker is UL Listed, CE Marked, and CSA Certified, with additional third-party approvals from Lloyd's Register and ANSI. It also aligns with other certifications noted in Eaton’s datasheets, ensuring suitability for global projects and regulated facilities.
Resources include the Magnum PXR user manuals, application notes (zone selective interlocking, selective coordination), product datasheets, and quick-start guides. Online papers on protection coordination and Power Xpert Protection Manager compatibility support design accuracy, accelerating commissioning and reducing downtime, which improves return on investment over panel life cycles.
