FAQs
Installation involves a controlled, parallel-mount approach to the drawout breaker with the motorized racking mechanism enabled. Ensure the cabinet is de-energized per your lockout/tagout procedures, verify alignment with the drawout rails, and connect the PXR25 protection unit for coordinated operation. Follow manufacturer manuals for torque specs and seating to prevent misalignment and nuisance trips.
The MPS86A4MEAXX2Q offers a four-pole configuration with an 85 kA short-circuit rating and a 6000 A interrupt capacity (NABCNABC). It uses the PXR25 LSIAM trip unit for motor protection and selective coordination, and it supports motorized racking for fast, safe insertion and removal in drawout applications.
Yes. The four-pole, drawout design with motorized racking is ideal for motor control centers and large panels where uptime and easy maintenance are critical. The PXR25 trip unit supports precise coordination, while the rugged construction and high interrupt capacity protect against faults that could propagate through an MCC or panelboard.
The Magnum PXR family, including this model, carries UL Listed, CSA Certified, and CE Marked approvals, along with additional certifications such as KEMA and Lloyd's Register. These certifications confirm compliance with major global standards for safety, performance, and reliability in varied industrial environments.
Power Xpert Protection Manager enables centralized protection configuration, real-time diagnostics, and streamlined maintenance planning. This reduces unplanned downtime, improves fault diagnosis speed, and simplifies asset management, delivering a favorable ROI through lower maintenance costs, longer equipment life, and more predictable production schedules.
