FAQs

The MPSC164WEAXX2S uses a standard Magnum frame with four poles and is designed for drawout vertical mounting in traditional power distribution panels. Its 1600 A Iu rating and 100 kAIC interrupt capability make it suitable for high-current feeders, motor control centers, and panelboard assemblies, while maintaining compatibility with Power Xpert Release trip units for optimized protection schemes.
Key specs include rated uninterrupted current Iu of 1600 A, interrupt rating of 100 kAIC, four-pole configuration, standard frame, and drawout vertical mounting. Overall dimensions are 14.6 in depth, 16.8 in height, and 21.2 in width with a weight around 160 lb. Trip unit is PXR25 LSIGAM, compatible with Magnum PXR protection schemes.
This model is UL Listed and CE Marked, with ANSI/CSA certification as part of its multi-region compliance. It also carries additional marks like NEMA compliance, CCC, SABA, Lloyd's Register, DNV GL, and ABS certifications, reinforcing global acceptance and reliability for industrial applications.
The PXR25 LSIGAM trip unit provides advanced protection logic, enabling zone selective interlocking and coordinated protection across panels. This reduces nuisance trips, speeds fault clearance, and improves coordination with upstream protection, enhancing safety and system reliability in complex electrical networks.
Plan for a drawout vertical-mount installation within standard Magnum frames, ensuring alignment with panel enclosures and space for four-pole breakers. Access and interchangeability with renewal parts and accessories are supported, which simplifies maintenance, minimizes downtime, and lowers lifecycle costs over the equipment’s service life.
