FAQs

This model uses a drawout vertical mounting with extensions, designed for standard double-standard frames and four-pole configurations. It fits most LV distribution panels built for Magnum PXR devices and pairs with common rail systems. Ensure adequate clearance for the 16.3 inch depth, 16.8 inch height, and 44.1 inch width, and verify compatibility with existing protection schemes and mounting rails.
The PXR20 LSI trip unit delivers fast, selective tripping based on load current and fault sensing, improving coordination across feeder stages. It supports precise fault isolation, reducing nuisance trips and enabling faster restoration. It also offers advanced diagnostics compatible with Power Xpert Protection Manager for remote visibility and event analysis.
Yes. With a 6000 A Iu rating and 85 kAIC interrupt capability, the MPS86A4EEAXX2A is suited for high-demand, mission-critical loads found in data centers and motor-driven processes. The four-pole, drawout configuration supports reliable phase coordination, while UL Listed and CE Marked certifications meet industry safety and regulatory standards.
The breaker carries UL Listed and CE Mark certifications, along with ANSI, CSA, KEMA, ABS, Lloyd's Register, and DNV GL endorsements. NEMA compliance and CCC Marking also appear in the spec sheet. This broad certification set supports cross-border deployments, audits, and license-to-operate in diverse markets.
Maintenance benefits come from access to Magnum renewal parts and documented spare-parts availability. The device is integrated into Eaton’s protection ecosystem, enabling streamlined upgrades and serviceability. When planning lifecycle costs, consider availability of replacement trip units and drawout extensions, as well as compatibility with Power Xpert Protection Manager for ongoing health checks.
