Feature: Three-pole, standard-frame Magnum PXR assembly delivers consistent protection across all phases, enabling modular protection strategies. Business Impact: Improves selective coordination with downstream devices, reducing nuisance trips and stabilizing bus performance in high-demand lines. Application: Ideal for distribution panels, motor control centers (MCCs), and switchgear in manufacturing and process plants requiring scalable protection and quick retrofits. Feature: 100 kAIC interrupt rating withstands high-energy fault currents common in large motors and feed-throughs. Business Impact: Minimizes equipment damage and downtime by absorbing fault energy, supporting faster recovery and safer maintenance. Application: Suitable for feeder cables, transformer feeders, and critical lube systems in heavy industry and data centers where fault energy must be limited. Feature: Rated uninterrupted current (Iu) of 2500 A with the PXR25 LSI ARMS trip unit delivers precise overload protection and arc-energy management. Business Impact: Reduces unplanned outages and improves protective coordination with downstream devices through ARMS-based selective protection. Application: Large load circuits and high-capacity motor loads, such as extrusion lines and stamping presses. Feature: Drawout vertical mounting with motorized racking simplifies maintenance and testing. Business Impact: Cuts maintenance time, improves safety during pull-out operations, and enables remote or automation-assisted trip unit replacements. Application: Panelboards and switchgear assemblies in high-availability environments where downtime must be minimized. Feature: Magnum PXR family in a standard frame supports easy upgrades and cross-reference with existing stock. Business Impact: Lower lifecycle costs by enabling retrofits, spare parts commonality, and simplified field service. Application: Retrofit projects across legacy installations and new builds with consistent protection devices. Feature: Broad certifications including UL Listed, CSA Certified, ANSI, Lloyd's Register, CE Marked; SABA Listed; NEMA Compliant. Business Impact: Ensures procurement compliance across US, Canada, and Europe, simplifying supplier qualification and regulatory adherence. Application: Global manufacturing, food and pharma facilities, and energy-intensive industries with strict standards. Feature: 14.6 in depth, 16.8 in height, 16.2 in width, 118 lb weight. Business Impact: Provides predictable footprint for panel planning and installation, reducing space-planning risk. Application: OEM equipment retrofits and new builds with tight space constraints.

FAQs
The MPSC253MEAXX2Q uses a drawout vertical mounting with motorized racking, compatible with standard Magnum panel configurations. Wire the three poles to the correct line and load terminals per the included wiring diagrams, ensuring proper clearances and secure connections. The PXR25 LSI ARMS trip unit supports coordinated protection and straightforward field servicing.
The 100 kAIC interrupt rating equips the breaker to safely interrupt high-energy faults, reducing the risk of equipment damage and arc flash energy. This translates to lower repair costs and shorter downtime in facilities with large motor loads or high fault currents, while maintaining selective coordination with downstream devices.
Yes. The three-pole Magnum PXR device with a 2500 A Iu and 100 kAIC rating is well-suited for MCCs and heavy-load panels in manufacturing environments. Its motor protection compatibility, drawout design, and protection coordination help protect motors and feeders from overloads and faults, supporting high availability on critical production lines.
This breaker carries UL Listed, CSA Certified, and CE Marked certifications, among others, signaling compliance with US, Canadian, and European standards. For global deployments, these certifications streamline supplier qualification, regulatory approvals, and cross-border procurement, reducing project risk and ensuring consistent performance across sites.
Expect reduced maintenance time due to motorized racking and a safer pull-out process, which lowers labor costs and downtime. The durable Magnum PXR protection and wide certification footprint also minimize spare parts variety and simplify replacements, contributing to a lower total cost of ownership over the equipment lifecycle.
