Quick Summary

Eaton Magnum low voltage power circuit breaker protects electrical distribution by interrupting fault currents in industrial plants. Engineers often face nuisance trips and unplanned downtime when protection isn't selective or quickly retrievable for servicing. UL Listed, CE Marked, and NEMA Compliant certifications ensure global acceptance and reliable performance in demanding environments. Coupled with the Power Xpert Release PXR20 trip unit, it accelerates maintenance, improves coordination, and supports scalable automation projects. In high-demand facilities, the three-pole, 800 A frame with motorized racking reduces downtime during maintenance and retrofit cycles. This combination delivers safer, faster trips and easier retrofits for motor control centers and panel boards.

FAQs

Installation uses the drawout vertical mounting with motorized racking for safe, rapid insertion and removal. Ensure clearance for the standard frame, connect the three-pole assembly to the bus and feeder wiring, then configure the PXR20 LSIG trip unit settings via the protection manager tools. This enables efficient commissioning and minimal downtime during panel upgrades.
The PXR20 LSIG trip unit provides precise overcurrent protection with programmable coordination, improving selectivity and reducing nuisance trips. It supports advanced protection schemes and easier troubleshooting, which is critical for motor control centers and high-demand manufacturing lines seeking reliable fault isolation without unnecessary interruptions.
Yes. The MPSC083MEAXX2C carries UL Listed and CE Marked certifications, along with NEMA Compliance, CCC Mark, and other recognized standards. This combination ensures acceptance across North American and international projects, simplifying procurement and installation in multi-site operations.
Plan routine checks of the trip unit calibration, lubrication of drawout components, and periodic actuations to verify motorized racking is functioning. With the PXPM integration, you can schedule remote health checks and firmware updates to minimize on-site service time while sustaining protection performance for 800 A loads and 100 kA fault currents.
The unit's high interrupting capacity, ride-through reliability, and factory-certified protections reduce unplanned downtime and equipment damage. The motorized racking and PXPM compatibility streamline maintenance and monitoring, delivering longer service intervals, easier upgrades, and lower total cost of ownership for large-scale automation projects.
