Drawout vertical with motorized racking enables safe, rapid breaker replacement during commissioning or maintenance, reducing arc-flash exposure and downtime. In panel designs, this compatibility supports hot-swapping without full-system shutdown, accelerating project timelines and lowering maintenance costs. Three-pole construction with a 5000 A interrupting capacity (ABCABC) and a 100 kA short-circuit rating delivers robust protection for feeders and motors, improving uptime in heavy-usage environments and reducing fault-related damage. The no trip unit configuration simplifies procurement and minimizes upfront costs while still enabling coordination with Magnum PXR protection if future upgrades are pursued. The compact yet substantial footprint (16.3 in L, 16.8 in H, 31.1 in W) and a 237 lb weight enable integration into standard switchgear racks, reducing design concessions and enclosure complexity. Global compliance is built in through UL Listed, CE marked, ANSI, and NEMA certifications, supporting international projects. Although shipped without a trip unit, it remains compatible with Power Xpert Release units for advanced coordination, giving users a clear migration path as protection needs evolve.

FAQs

Installers should ensure vertical drawout mounting space within standard enclosures, verify clearance for motorized racking operation, and confirm alignment with panelbus stabs. Allow for service clearances on both sides to enable safe rack-and-replace procedures and cable management within the enclosure.
It is a three-pole device with a 5000 A interrupting capacity (ABCABC) and a 100 kA short-circuit rating, suitable for heavy feeders and motor circuits in demanding industrial environments. The unit ships without a trip unit, enabling tailored coordination with compatible protection modules if desired.
Yes. The breaker carries UL Listed and CE marked certifications, and complies with ANSI and NEMA requirements, supporting usage in globally regulated panel assemblies and equipment builds.
The current unit ships without a trip unit, but it is compatible with Magnum PXR protection units. This provides a pathway to advanced coordination and protection upgrades without replacing the breaker housing.
Motorized racking supports safer, faster breaker removal and installation, reducing exposure to live parts during maintenance. It enables efficient hot-swapping and simplified maintenance planning, which translates to lower downtime and improved overall equipment effectiveness.
