FAQs

Yes. The MPSC5N3HEAXXSW is designed for fixed horizontal mounting and three-pole protection in standard low-voltage panels and switchgear. Its dimensions (16.3 in L x 16.8 in H x 31.1 in W) and weight (237 lb) should be accounted for in enclosure planning, but it fits typical Magnum frame installations without special adaptors. Always verify enclosure space and mounting provisions before procurement.
The breaker supports a 5000 A current rating with a 100 kA short-circuit interrupt capacity, aligning with rugged industrial protection needs. This combination reduces fault energy transfer, enhances personnel safety, and minimizes damage to connected motors and feeders during fault events.
Yes, it is suitable for global installations. The unit carries UL Listed and ANSI certifications, CE Marking, and additional approvals including CSA, Lloyd's Register, KEMA, ABS, DNV GL, and SABA listings. These certifications support compliance across North America, Europe, and other regions, simplifying cross-border procurement and installation.
While the MPSC5N3HEAXXSW ships with no trip unit, there are communications and documentation assets for Magnum PXR protection and Protection Manager. Upgrading paths exist to add trip units later and integrate with protection management workflows, enabling selective coordination and enhanced monitoring in evolving automation schemes.
Expect robust, low-maintenance protection thanks to its fixed frame and no-trip-unit configuration. Routine checks should focus on enclosure environment, contact status, and connection integrity. For lifecycle optimization, plan for potential upgrade to PXr trip units or Protection Manager integration in future projects to extend protection features and align with evolving safety standards.
