The device uses a three-pole configuration with a 4000 A frame and a 100 kA interrupting rating, which enables rapid fault isolation in high-current environments and minimizes arc exposure in heavy industrial switchgear. This translates to shorter downtime and enhanced personnel safety during fault events, supporting reliable manufacturing operations and process control. Although shipped without a trip unit, the frame is engineered for easy retrofitting with Magnum PXR Power Xpert Release trip units, enabling advanced protection schemes when needed and reducing spare parts diversity during upgrades. Global certifications such as UL Listed, CE Marked, CSA, KEMA, ANSI, and Lloyd's Register streamline regulatory approvals and risk management across regions, while the renewal parts catalog supports long-term lifecycle planning and cost control. Fixed horizontal mounting and a 3-pole design simplify installation in existing layouts, reducing commissioning time and ensuring balanced phase protection. Compatibility with Power Xpert Protection Manager enables remote monitoring, event data access, and coordinated protection strategies for improved system reliability.
