This design reduces commissioning time, improves fault isolation during maintenance, and minimizes panel downtime. It is compatible with standard Magnum frame enclosures and can be integrated into existing four-pole, drawout-ready assemblies without heavy rewiring.
This breaker features a four-pole configuration with a high interrupt rating up to 100 kA and a 5000 A frame rating (NNAABBCC). These specifications translate to robust protection for large motor drives and feeder circuits, enabling fast, reliable fault clearance in demanding industrial environments while maintaining panel integrity.
Yes. The unit is UL Listed and CE marked, with CSA certification and NEMA compliance noted for global deployment. Additional certifications in the Magnum family include KEMA, Lloyd’s Register, DNV GL, and ABS, offering broad regulatory acceptance and smoother cross-border commissioning in multinational facilities.
The Magnum line supports Power Xpert Release trip units, allowing future upgrade without replacing the breaker body. This provides advanced protective functions, improved coordination, and easier integration with Power Xpert Protection Manager for enhanced monitoring and fault reporting, reducing total cost of ownership over the asset lifecycle.
With its drawout design and modular trip-unit compatibility, maintenance actions are streamlined, reducing downtime and labor costs. The upgradable PXr path enables longer asset life, improved protection coordination, and faster fault diagnosis, delivering measurable ROI through reduced unplanned outages and extended equipment life in automated facilities.
