FAQs

The MPS8503MEAXX2S uses a drawout vertical mounting with motorized racking, designed for retrofit into Magnum frame-compatible panels. When planning installation, verify frame compatibility, ensure proper clearance for the 31.1 in width, and follow the motorized racking sequence to minimize arc exposure. Confirm wiring torque specs and connect to the PXR25 LSIGAM trip unit for coordinated protection. Use the zone-interlocking guidance papers for best results in selective coordination and safe maintenance.
This breaker offers an 85 kA interrupting rating with a 5000 A ABCABC frame capability, making it suitable for high fault-current environments. Choose 85 kA in applications with high short-circuit potential, such as large motors, pumps, or feeders subject to brief-circuit events. For enhanced coordination and diagnostic capabilities, pair with Power Xpert Release trip units and adopt selective coordination strategies to minimize nuisance trips.
Yes. The MPS8503MEAXX2S is designed for motor-protection-centric applications, leveraging the PXR25 LSIGAM trip unit for precise protection. It supports motor startups, overload protection, and coordinated tripping with downstream devices. For best results, align protection settings with motor FLA, startup currents, and panel coordination plans, and utilize the Power Xpert ecosystem for remote monitoring and maintenance planning.
The unit features UL Listed, CE Marked, and CSA Certified approvals, with additional certifications from Lloyd's Register, KEMA, ABS, DNV GL, and others noted in the documentation. It also meets NEMA compliance requirements and SABA listing per the provided specs. These certifications support global deployment, regulatory adherence, and customer confidence in safety and performance across multiple regions.
Motorized racking enables safer, faster insertion and removal without manual manipulation of hot connections, reducing risk during maintenance. The drawout vertical design simplifies fault isolation and testing, shortening maintenance windows and improving uptime. Combined with the PXR trip unit, it also supports quicker diagnostics and streamlined firmware updates, delivering lower total cost of ownership over the equipment lifecycle.
