FAQs

Plan for a standard Magnum frame device with drawout vertical mounting and motorized racking. Verify the enclosure footprint fits 16.2 in wide, 16.8 in high, and 14.6 in deep, with an approximate 118 lb weight. Use NEC-compliant wiring, proper lugs, and leave space for racking motion. Coordinate with existing protection schemes to ensure seamless switchgear operation.
Key specs include 3200 A current rating, 100 kA interrupting capacity, three-pole configuration, and PXR20 LSIAM trip unit. This enables reliable motor protection, safe fault interruption, and precise coordination with upstream devices. The drawout design also simplifies testing and replacement without energizing downstream circuits.
Yes. It is well-suited for process automation and heavy-duty motors where uptime and selective coordination matter. The PXR20 trip unit with LSIM allows adjustable protection and diagnostic visibility, while motorized racking reduces maintenance time and risk. For critical loads, pairing with Power Xpert Protection Manager improves monitoring and response.
It carries UL Listed, ANSI CSA Certified, and CE Marked certifications, with additional attestations from Lloyd's Register, KEMA, ABS, and DNV GL. This breadth supports global deployments, regulatory compliance, and supplier audits, reducing certification risk for panel builders and OEMs across regions. Other regional marks like SABA and NEMA compliance further expand acceptance.
The unit's drawout design, motorized racking, and compatible Power Xpert Protection Manager ecosystem reduce maintenance time and improve fault diagnosis. Availability of renewal parts and documented datasheets from Eaton support long lifecycle performance, lowering total cost of ownership through fewer unplanned outages and easier part replacement.
