Drawout vertical mounting with motorized racking improves installation speed and safety. The motorized racking reduces manual handling and misalignment during insertion or withdrawal, shortening commissioning time and lowering arc-flash exposure for technicians. This is ideal for retrofit panels and new builds in heavy manufacturing and data centers where downtime costs matter. The PXR25 LSIAM trip unit provides precise trip curves and long-term stability for selective coordination. It enables tailored protection for feeders and motors, minimizing unnecessary outages while preserving safe margins under fault conditions. In practice, engineers can configure protection to align with zone-selective interlocking and downstream devices. With a 2500 A frame and 100 kA short-circuit withstand, this breaker handles large motor feeders and bus sections without compromising protection. The four-pole design supports balanced fault clearing, while the drawout form factor simplifies maintenance in vertical switchgear. Compliances include NEMA, CE Marked, SABA Listed, and UL Listed, enhancing global procurement and regulatory alignment. The Magnum ecosystem compatibility, plus Power Xpert Protection Manager integration, enables remote monitoring and diagnostics to reduce on-site service visits and extend asset life. This combination delivers faster fault isolation, reduced maintenance costs, and improved safety across industrial facilities.

FAQs
For new installations, plan for a drawout breaker with vertical mounting and motorized racking to maximize commissioning speed. Ensure the panel enclosure provides adequate clearance for rack-in/out operations and verify compatibility with Magnum accessories and protection manager software. Verify wiring, bus connections, and trip-unit settings are aligned with the system protection philosophy to optimize coordination and safety.
Key specs include a 2500 A current rating, 100 kA interrupting capacity, four-pole configuration, and a PXR25 LSIAM trip unit. It is a standard-frame, drawout breaker with motorized racking and supports selective coordination. These specs ensure robust protection for large feeders and motors while enabling fast fault clearing in demanding environments.
Yes. The 2500 A rating, 100 kA capacity, four-pole design, motorized racking, and advanced PXR trip unit make it well-suited for high-demand motor feeders and critical loads common in data centers and heavy manufacturing. Its protection coordination and robust construction help maintain uptime and reduce unplanned outages.
The device is UL Listed, CE Marked, and NEMA compliant, among other certifications such as CSA, ABS, DNV GL, and KEMA. These certifications support global compliance, simplify cross-border procurement, and help meet diverse regulatory requirements for equipment installed in multinational facilities.
Protection Manager integration enables remote monitoring, diagnostics, and streamlined configuration of trip settings, reducing on-site maintenance visits and accelerating fault diagnosis. The improved selectivity and rapid fault isolation translate to lower downtime, extended asset life, and a lower total cost of ownership over the breaker’s lifecycle.
