FAQs

For fixed horizontal mounting, ensure adequate clearance for bus connections and sufficient space to accommodate the 14.6 in depth, 16.8 in height, and 16.2 in width. Verify panel cutouts align with the three-pole footprint, and allow room for PXR wiring and field wiring terminations. Compliance with mounting guidelines reduces installation time and minimizes misalignment risks.
The PXR20 LSI trip unit provides precise current sensing and logic-based tripping. This enables fast, selective fault isolation, limiting disturbance to unaffected portions of the system. In practice, this reduces upstream nuisance trips and short downtime, improving overall system reliability in multi-bus power distributions.
Yes, the MPSC203HEAXX2A carries UL Listed and CE Marking, along with additional certifications. This dual accreditation supports compliance with North American and European regulatory requirements, simplifies audits, and satisfies customer procurement standards in regulated industries such as energy, chemicals, and water treatment.
Engineers should verify compatibility with the Magnum PXR trip unit family and check renewal parts availability for ongoing maintenance. The MPSC203HEAXX2A supports Power Xpert Release integration, enabling straightforward upgrades from legacy breakers and streamlined spares management across existing switchgear fleets.
Expect reduced unplanned downtime due to faster fault clearance, lower downstream damage from high-energy faults, and simplified maintenance with standardized PXR components. The 2000 A frame and 100 kA rating provide robust protection for high-current feeders, translating to longer equipment life and lower lifecycle costs over retrofit or new installations.
