High interrupt rating and Iu rating deliver reliable protection for large motor loads, enabling faster fault isolation and reduced downtime in manufacturing and process environments. The 85 kAIC capability minimizes fault energy transfer to equipment, supporting longer asset life and safer start-up sequences. Drawout vertical mounting with extensions and motorized racking simplifies maintenance and upgrades, reducing line-side interruption time and labor costs during panel servicing. The double standard frame and four-pole configuration ensure compatibility with existing MCCs and switchgear, streamlining installation and future expansion. Global certifications, including UL Listed and CE Marked, reduce compliance risk across sites and accelerate commissioning. The no-trip-unit configuration offers flexibility to tailor protection schemes with compatible trip units, optimizing protection without over-specification. Comprehensive physical dimensions and weight information support accurate enclosure planning and retrofits in tight spaces.
