FAQs
Fixed vertical mounting simplifies cabinet design and provides a stable, space-efficient footprint. Ensure enclosure clearances match the 16.3 in depth, 16.8 in height, and 44.1 in width, and accommodate the 319 lb weight. Use correct torque settings for bus connections and verify mounting plane alignment to maintain optimal trip performance and safety.
The PXR25 LSIGAM trip unit delivers electronic protection settings that enhance selectivity and fault isolation speed. It supports zone-selective coordination when paired with compatible protection schemes, reducing nuisance trips and shortening downstream fault clearing times. This helps protect critical loads while lowering maintenance complexity in motors and drives applications.
Yes. The MPSC4A4VEAXX2S is UL Listed, CE Marked, and CSA Certified, with additional approvals including NEMA Compliance, SABA Listing, and other regional certifications (Lloyd's Register and KEMA among them). This broad certification profile supports global procurement, cross-border installations, and consistent performance across multiple markets.
Ideal for industrial power distribution and control panels, this four-pole breaker is well-suited for manufacturing lines, process industries, and data centers. Its high short-circuit rating and robust protection features support heavy-duty motors, conveyors, presses, and other high-inertia loads, enabling safer operation, reduced downtime, and easier system upgrades.
Integrating Magnum PXR with Power Xpert Protection Manager enables remote health monitoring, proactive maintenance planning, and streamlined spare-part management. The combination reduces unplanned outages, extends service life, and improves overall asset reliability. Although initial integration requires configuration, long-term energy efficiency and uptime gains typically deliver a favorable ROI.
