Drawout vertical mounting with motorized racking enables fast, safe breaker replacement and safer maintenance operations. This capability reduces downtime and minimizes arc-flash exposure during servicing, delivering tangible productivity gains in busy manufacturing lines. Use in motor control centers, switchgear, and feeder panels benefits from quick unit swaps without powered-down re-wiring, improving maintenance efficiency and uptime. With an 85 kA SCCR and a 6000 A frame rating, the breaker delivers robust protection for high fault currents in heavy machinery and process lines. The three-pole design provides balanced protection and consistent trip performance, while fan cooling supports reliability in hot plant areas, enabling selective coordination and reduced nuisance trips. Although sold as a no-trip-unit variant, it is designed to pair with Magnum PXR Power Xpert Release trip units for advanced protection schemes, delivering precise coordination and faster fault diagnosis. Built to comply with UL Listed, CSA, KEMA, Lloyd's Register, ANSI, DNV GL, ABS certifications, plus CE Marked and NEMA compliance, this unit simplifies global sourcing for multinational facilities. Its footprint fits standard mounting spaces in panelboards and switchgear, with dimensions of 16.3 in length, 31.1 in width, and 16.8 in height, weighing 237 lb, supporting straightforward retrofits and durable, long-life operation.
