High-current protection with a rated uninterrupted current (Iu) of 5000 A and an interrupt rating of 100 kAIC. This capability minimizes fault energy exposure, improves safety margins, and reduces unplanned downtime in heavy-load plants. Suitable for large industrial feeders, panelboards, and motor control centers where high fault currents are expected. The PXR20 LSI trip unit enables zone selective interlocking and precise fault sensing. This improves selectivity, reduces nuisance trips, and allows faster clearances upstream, ideal for data centers, foundries, and continuous-process lines requiring tight coordination with upstream devices. Magnum PXR double standard frame with fixed vertical mounting, three poles, provides robust, stable installation in large panels while simplifying field service with common mounting interfaces. This is particularly advantageous for large switchgear and wall-mounted panels where space and alignment matter. The breaker carries broad certifications (UL Listed, ANSI/KEMA, Lloyd's Register, CSA, ABS, DNV GL) and CE/NEMA compliance, supporting global deployments and streamlined procurement workflows. compatibility with Magnum PXR trip units and Power Xpert Release trip units, plus integration with Power Xpert Protection Manager, enables scalable protection strategies, centralized monitoring, and easier upgrades for both new builds and retrofit projects.

FAQs

The unit is designed for fixed vertical mounting in a three-pole, double standard frame. Plan for a 31.1 in wide footprint with 16.3 in depth and 16.8 in height, and prepare for a 237 lb installation. Verify panel clearance, busbar alignment, and mounting rails per Eaton installation guidance to ensure reliable operation and serviceability.
Key ratings include a rated uninterrupted current (Iu) of 5000 A and an interrupt rating of 100 kAIC. The device uses a PXR20 LSI trip unit for selective coordination and is configured as a three-pole breaker with a fixed vertical mount, suitable for large feeder protection and motor circuits.
Yes. With the PXR20 LSI trip unit and the Magnum PXR frame, the breaker supports zone selective interlocking and precise fault sensing. This enables improved selectivity, reduced nuisance trips, and faster fault clearance upstream, which is essential for data centers, manufacturing lines, and large motor feeders seeking reliable protection coordination.
This model carries UL Listed, ANSI/KEMA Certified, Lloyd's Register Certified, CSA Certified, ABS Certified, and DNV GL Certified, along with CE Marked and NEMA compliance. These certifications support global deployments, simplify supplier qualification, and help meet regulatory requirements across multiple regions, reducing project risk.
The ROI comes from high fault protection, reduced downtime, and compatibility with Power Xpert Release trip units and Power Xpert Protection Manager for centralized monitoring. The robust build, broad certifications, and availability of renewal parts help lower maintenance costs and extend service life in critical facilities.
