FAQs

The MPS8404WEAXX2C is designed for a Magnum PXR drawout system with a double standard frame and four-pole configuration. It supports vertical mounting and is compatible with existing PXR accessories, enabling straightforward replacement or expansion in established switchgear or distribution panels while maintaining proper protection coordination.
With an 85 kAIC interrupt rating and a 4000 A Iu continuous rating, the device withstands heavy fault currents while maintaining service continuity for large feeders. This is critical in manufacturing floors, metal processing, and heavy industries where fault events can be severe and rapid isolation is essential.
Key certifications include UL Listed, CE Marked, and CSA Certified, along with additional approvals like Lloyd's Register and KEMA in various regions. These certifications support regulatory compliance, safer procurement, and smoother approvals for global projects.
The PXR20 LSIG trip unit enables precise, selective protection coordination by tailoring tripping characteristics to downstream devices and loads. This reduces unnecessary trips, shortens fault-clearing times, and improves system reliability in complex networks typical of process industries and data centers.
The four-pole arrangement provides balanced protection for three-phase systems with a neutral, while the drawout vertical mounting simplifies inspection, testing, and replacement. This design minimizes downtime during maintenance and allows rapid reconfiguration or upgrades within existing switchgear infrastructure.
