FAQs

This breaker uses a drawout vertical mounting with motorized racking, designed to fit standard Magnum enclosures and typical low-voltage switchgear footprints. Check panel opening width, busbar spacing, and internal clearance to ensure full travel of the racking mechanism. Weight and dimensional data (14.6 in depth, 16.8 in height, 21.2 in width; 160 lb) should align with cabinet ratings and mounting provisions to avoid interference with adjacent devices.
The PXR25 LSIAM trip unit provides advanced electronic protection with precise long-time, short-time, and instantaneous protection curves, enabling selective coordination across feeders. This supports tighter fault isolation, reduces nuisance trips, and aligns with modern protection schemes. When paired with Power Xpert Protection Manager, it also offers enhanced visibility, event logging, and remote configuration for complex industrial systems.
Yes. The MPSC304MEAXX2Q carries UL Listed and CSA Certified marks, plus CE Marked and NEMA Compliant status, with CCC Marked options as applicable. This broad certification suite supports international deployment across North America, Europe, and select markets, simplifying procurement, qualification, and cross-border maintenance for multinational facilities.
Motorized racking allows safe, quick removal and installation of the breaker without manual front-front handling or exposure to live parts in most configurations. This reduces maintenance time, lowers crew exposure to electrical hazards, and streamlines periodic replacement or testing cycles, delivering faster recovery after faults and easier scheduled maintenance in high-availability environments.
The upgrade delivers measurable ROI through reduced downtime from faster maintenance and safer retrofit operations, improved protective coordination with the PXR25 unit, and potential energy and fault-loss reductions from more precise protection. Global certification support also lowers lifecycle procurement friction for multi-site operations, while Power Xpert ecosystem compatibility enables proactive monitoring and informed maintenance planning.
