FAQs

The unit is designed for drawout vertical mounting with motorized racking in standard Magnum PXR frames, three-pole configuration, and a double standard frame. Check panel depth and clearance to ensure the 16.3 in length, 31.1 in width, and 16.8 in height fit your enclosure and allow for safe motorized operation.
Key specs are Iu of 4000 A and an interrupt rating of 100 kAIC, which support robust fault handling and short-circuit energy absorption. The PXR20 LSIGAM trip unit provides advanced protection logic, enabling selective coordination with downstream devices and improved reliability for large motors.
Yes. The three-pole, dual-frame Magnum PXR design with motorized racking simplifies maintenance in dense panel environments and supports precise protection coordination, critical for data centers and high-throughput manufacturing lines where uptime is essential.
It is UL Listed, KEMA Certified, ANSI, Lloyd's Register Certified, CSA Certified, DNV GL Certified, ABS Certified, and CE Marked with NEMA compliance, plus CCC Marked in applicable regions. This broad certification set supports global projects and compliance requirements.
Motorized racking reduces maintenance cycles by enabling quick, safe removal and replacement of breakers, cutting downtime during servicing. When combined with the PXR protection system and Power Xpert Manager integration, this can lower total cost of ownership through faster repairs, easier diagnostics, and improved protection coordination.
