High interrupt rating and current capability provide robust protection for heavy feeders, reducing arc flash exposure and equipment damage; the business impact is lower downtime and fewer spare parts. This is ideal for large manufacturing lines and data centers where reliability drives uptime and throughput. The PXR25 LSI ARMS trip unit enables zone-selective interlocking and coordinated protection, which translates to fewer nuisance trips and safer maintenance windows, especially during plant start-ups or load changes. The fixed horizontal mounting and standard frame simplify retrofits into existing switchgear and panel boards, cutting installation time and risk while preserving enclosure space. Comprehensive certifications and CE marking streamline multi-region procurement and regulatory compliance for global projects. Dimensions and weight (14.6 in depth, 16.8 in height, 16.2 in width, 118 lb) support planning in tight electrical rooms. Compatibility with Magnum PXR and Protection Manager enables centralized monitoring and remote configuration, improving asset visibility and lifecycle management. In practice, engineers gain confidence to consolidate protection schemes across sites, reducing total cost of ownership and accelerating project timelines.

FAQs

The MPSC323HEAXX2Q is a three-pole, standard-frame breaker designed for straightforward drop‑in installation in Magnum panels. It uses fixed horizontal mounting compatible with Magnum PXR trip units and Power Xpert Protection Manager ecosystems. For best results, verify enclosure space, wiring clearances, and alignment with the PXR25 LSI ARMS settings to ensure proper coordination and reliable protection without enclosure modifications.
3200 A Iu indicates the rated uninterrupted current the breaker can carry without tripping under normal conditions, while 100 kAIC is the interrupt rating, denoting the maximum short-circuit current the device can safely interrupt. This combination supports heavy feeders and large motors, reducing the risk of catastrophic damage and enabling safer, more reliable distribution in multi‑megawatt facilities.
Yes. With three-pole configuration, PXR trip unit, and high interrupt rating, the MPSC323HEAXX2Q is well suited for 3‑phase motor protection, main feeders, and distribution circuits in heavy manufacturing. Its selective coordination features help maintain motor protection while minimizing downtime during faults, and it integrates with protection management systems for enhanced monitoring and control.
This breaker carries UL Listed, CSA Certified, ANSI/KEMA/ DNvGL style certifications, along with CE Marked compliance. These credentials support global procurement by meeting widely accepted safety and performance standards, reducing risk in multinational projects, and simplifying qualification for regulated environments, audits, and supplier qualification processes.
Consider lifecycle costs tied to protection accuracy, uptime, and spare parts availability. The Magnum PXR with LSI ARMS reduces nuisance trips and enables predictive maintenance through Protection Manager integration. Renewal parts and service programs from Eaton help maintain consistent protection performance, while higher available fault current handling can reduce capital expenditures on downstream devices, contributing to a favorable return on investment over the system’s life.
