FAQs

The MPS85N3WEAXX2Q uses the Magnum PXR trip unit family and is designed for drawout vertical mounting in three-pole configurations. It is compatible with Power Xpert Protection Manager for centralized protection coordination, diagnostics, and software-based configuration. This simplifies project design, allows seamless upgrades, and supports consistent settings across multiple breakers in distributed installations.
Key specs include a 3-pole configuration, 85 kA short-circuit withstand, and a 5000 A interrupting rating. The unit employs a PXR25 LSIAM trip unit for precise tripping, and the device is UL Listed and CSA Certified with CE Marking, ensuring reliability and cross-border compliance in industrial environments.
Yes, with the PXR trip unit and the high interrupting capacity, the Magnum is well-suited for selective coordination in medium to large switchgear and panel boards. When paired with proper relays and protection schemes, it minimizes upstream disturbances and improves service continuity for critical loads on manufacturing lines.
This model carries UL Listed, CSA Certified, CE Marked, and Lloyd’s Register certifications, along with ANSI, KEMA, ABS, and DNV GL approvals. These certifications support regulatory compliance, simplify supplier acceptance during audits, and enable deployment across diverse international sites with confidence in safety and performance standards.
The unit’s drawout design reduces maintenance time by enabling quick pull-out replacements, while the PXR trip unit simplifies diagnostics and configuration. Global certifications and extensive manuals accelerate commissioning. Collectively these factors reduce downtime, extend mean time between failures, and lower lifecycle costs when compared to non-compatible or non-diagnostic protective devices.
