Feature: Magnum PXR trip unit family provides coordinated protection with adjustable electronic release. Business Impact: enables precise current-based protection and faster fault isolation, reducing unplanned downtime. Application: ideal for motor control centers and panel boards where selective tripping and remote monitoring improve maintenance windows and safety. Feature: High interrupt capability of 5000 A and 85 kA SCCR supports heavy-duty fault handling. Business Impact: greater fault tolerance prevents cascading trips and minimizes equipment damage, lowering maintenance costs. Application: large machines and feeders in process lines where fault currents can spike. Feature: Three-pole, fixed vertical mounting reduces footprint and simplifies retrofit. Business Impact: saves panel space and simplifies mounting in existing switchgear; supports quick upgrades during outages. Application: upgrading legacy MCCs or panel boards in new builds. Feature: Broad compliance and global certification set (UL Listed, CE Marked, ANSI/CSA). Business Impact: smooth cross-border deployment and easier supplier qualification, saving engineering time. Application: multinational facilities and compliance-driven projects. Feature: Documentation and toolchain integration with Power Xpert Protection Manager; availability of manuals, application notes, and time/current curves. Business Impact: enables faster commissioning, easier configuration, and centralized protection management for plant-wide reliability. Application: enterprise-wide protection schemes and remote monitoring environments.

FAQs

Verify panel compatibility with fixed vertical mounting, then shut down power and follow the manufacturer's wiring diagram. Mount the breaker in the designated slot, connect L1-L3 with proper torque, install the PXR25 trip unit, and program any required trip setpoints. Perform a functional test per the Magnum PXR manual and zone interlocking guidelines to ensure correct operation.
The unit is a three-pole device with a 5000 A interrupt rating (AIC) and a short-circuit current rating of 85 kA. It uses the PXR25 LSIAM trip unit and is designed for fixed vertical mounting, aligning with Magnum PXR specifications for reliable protection in industrial power distribution.
Yes. The PXR trip unit family supports coordinated protection, and when paired with zone selective interlocking and proper device selection in MCCs, it enables selective tripping. This minimizes unnecessary outages while preserving rapid isolation of faulted circuits, a key requirement in modern motor control centers.
This breaker carries UL Listed certification and CE Marking, along with ANSI and CSA certifications. Additional approvals include KEMA, Lloyd's Register, ABS, DNV GL, and other recognized bodies, reflecting broad compliance for global deployment in accordance with regional electrical codes.
Access engineering manuals, application notes, and renewal parts through Eaton's documentation library. Compatibility with Power Xpert Protection Manager supports centralized configuration and monitoring. Regularly updating trip unit firmware, training operators, and leveraging available service documentation helps reduce downtime and extend service life of the protection scheme.
