FAQs

The MPSC503MEAXX2H uses a drawout vertical design with motorized racking, enabling safe, rapid insertion and withdrawal in panelboards and motor control centers. This minimizes maintenance exposure, reduces downtime during servicing, and simplifies retrofits in existing switchgear while preserving alignment with standard mounting footprints.
This is a three-pole Magnum breaker with a 5000 A frame rating (ABCABC) and a 100 kA short-circuit current rating. It employs the PXR20 LSIAM trip unit for precise protection logic. Dimensions are 16.3 in depth, 16.8 in height, and 31.1 in width, with a weight of 237 lb, making it suitable for large panelboards and MCCs.
Yes. The unit is UL Listed and CE Marked, among other certifications including CSA Certified, KEMA, DNV GL, ANSI, and others. This broad certification suite simplifies procurement, facilitates cross-border deployments, and supports compliant installations in diverse regulatory environments.
Industries with high fault-current exposure and stringent reliability needs benefit most, including manufacturing, oil and gas, data centers, and process industries. The PXR20 LSIAM trip unit provides selective coordination and arc-energy management, helping to minimize outages and protect critical equipment.
Motorized racking streamlines breaker replacement and inspections, reducing manual handling and exposure to live components. The resulting time savings, safer operation, and improved uptime translate to lower maintenance labor costs, faster project completion, and a faster return on investment for facility modernization programs.
