Four-pole, double standard frame enables high-current distribution with compact footprint, simplifying panel design and reducing enclosure size while maintaining robust protection. This translates to faster commissioning, improved equipment uptime, and lower installation costs in data centers and manufacturing lines. The 4000 A Iu rating supports large motor starting and heavy loads, improving dependability and reducing nuisance trips during surge events for critical processes. With a 100 kAIC interrupt rating, the breaker delivers enhanced fault clearance and system reliability, minimizing downstream damage and downtime in demanding environments such as metals, mining, and process industries. The PXR25 LSIGAM trip unit provides selective coordination and arc-safety features, enabling smarter protection schemes and easier settings management through Power Xpert Release integration. Compatibility with Power Xpert Protection Manager streamlines configuration, monitoring, and firmware updates, delivering centralized protection management for multi-bay installations. The fixed vertical mounting and four-pole design support straightforward installation in standard switchgear and panelboards, reducing engineering time and improving retrofit efficiency across legacy systems.

FAQs
The MPSC404VEAXX2S is designed for fixed vertical mounting in four-pole configurations with Magnum PXR trip units. It fits standard low-voltage panelboards and switchgear, and its 44.1 in width and 16.8 in height align with common rack footprints. For retrofit projects, verify space for mounting clearances and ensure the PXR trip unit firmware matches Power Xpert Protection Manager requirements.
This breaker carries UL Listed and CE Marked certifications, plus NEMA compliance. It also holds CSA, KEMA, Lloyd’s Register, ANSI, DNV GL, and ABS certifications, with additional approvals such as UL Certificate of Compliance for Magnum PXR assemblies. These certifications support global deployment and regulatory alignment for industrial facilities.
Yes. The MPSC404VEAXX2S uses the PXR25 LSIGAM trip unit, enabling precise coordination with upstream devices. Its 4000 A Iu and 100 kAIC ratings support reliable selective protection for large motor loads and critical feeders, reducing the risk of cascading trips and enabling safer, more maintainable protection schemes in manufacturing cells and automation lines.
Key specs include a rated uninterrupted current (Iu) of 4000 A, interrupt rating of 100 kAIC, and a four-pole configuration with a double-standard frame. The unit is designed for fixed vertical mounting and uses the Magnum PXR trip unit, balancing high capacity with precise protection settings suitable for high-demand power distribution.
Power Xpert Protection Manager integration centralizes trip-unit configuration, monitoring, and firmware updates, reducing commissioning time and ongoing maintenance costs. This unified approach lowers total cost of ownership by improving protection accuracy, speeding fault diagnosis, and enabling proactive protection strategy adjustments across multiple switchgear bays.
