High interrupt rating of 85 kAIC provides robust feeder protection for demanding loads, reducing the risk of cascading faults and unplanned downtime. This translates to lower maintenance costs and improved system availability, particularly in large switchgear or panelboard assemblies where space is at a premium. The 5000 A Iu rating supports continuous operation for heavy motor circuits, enhancing uptime and operational efficiency in manufacturing lines or process plants. The PXR25 LSI ARMS trip unit offers precise line-side coordination, enabling selective fault isolation and faster fault clearing, which minimizes downstream impact and improves safety. The double standard frame and fixed vertical mounting simplify installation and replacement, reducing commissioning time and field labor costs while ensuring consistent alignment in dense switchgear. Comprehensive certifications (UL Listed, CE Marked, CSA Certified, Lloyd's Register) help you meet regulatory requirements across regions, accelerating project approvals and procurement cycles. Compatibility with Magnum PXR and Power Xpert Protection Manager enables seamless integration with digital protection schemes and remote monitoring, supporting Industrie 4.0 initiatives and long-term ROI through improved asset visibility.

FAQs

The MPS85N3VEAXX2Q uses the Magnum PXR trip architecture and is designed for compatibility with Power Xpert Release (PXR) trip units, specifically the PXR25 LSI ARMS. This enables integrated protection management within the Power Xpert Protection Manager ecosystem, supporting coordinated protection, remote monitoring, and simplified aftermarket upgrades across Magnum PXR breakers in existing panels.
This model is a three-pole unit with fixed vertical mounting, arranged in a double standard frame. The three-pole design is suited for three-phase distribution and motor protection schemes, while fixed vertical mounting simplifies alignment and vertical rack installation in panelboards and switchgear assemblies.
Key ratings include a rated uninterrupted current (Iu) of 5000 A and an interrupt rating of 85 kAIC. These specifications indicate strong fault-duty capability for large feeders and motor circuits, enabling reliable protection in demanding industrial applications while maintaining system uptime and facilitating proper coordination with downstream devices.
This breaker carries UL Listed, CE Marked, and CSA Certified approvals, and is also certified by Lloyd’s Register. Additional certifications include KEMA, ANSI, DNV GL, and ABS, reflecting broad regulatory acceptance for global projects. These certifications help streamline procurement, reduce vendor risk, and support cross-border installation without requalification.
Zone Selective Interlocking (ZSI) is supported through the Magnum PXR platform and available application guidance. For installation, ensure proper panel space for the 16.3 in length, 16.8 in height, and 31.1 in width, with fixed vertical mounting in a double standard frame. Refer to the ZSI application papers and Magnum PXR manuals to optimize fault isolation, coordination, and protection timing in complex distributions.
