FAQs
The MPS86A4GEAXX2Q uses a four-pole, drawout vertical design with extensions and motorized racking mounting. Plan for a Drawout vertical frame with a 16.3 in depth, 16.8 in height, and 44.1 in width footprint, with an approximate weight of 319 lb. Confirm panel bus connections and frame compatibility align with Magnum PXR units to ensure safe, compliant integration.
The 6000 A Iu rating provides robust uninterrupted current handling for heavy loads, while the 85 kAIC interrupt rating ensures rapid and reliable fault interruption. This combination reduces motor stall risk, minimizes arc energy exposure, and supports compliant protection during high-current startup transients typical in large motors and feeders.
Yes. The Magnum PXR trip unit (LSI ARMS) enables precise, adjustable protection settings that support selective coordination across multiple devices. This allows upstream devices to back off during a fault, isolating only the affected area and preserving continuity for non-impacted loads in critical processes.
This unit carries UL Listed, CSA Certified, CE Marked, and Lloyd's Register Certified marks, among others. The combination of these certifications, along with comprehensive manuals and application papers, simplifies procurement, audits, and cross-border commissioning for multi-site deployments.
The motorized racking and drawout design shorten maintenance windows by enabling quicker, safer breaker swaps, reducing panel downtime. The high Iu and 85 kAIC ratings reduce the likelihood of costly fault events, while global certifications streamline installation aboard diverse sites, contributing to lower lifecycle costs and a faster payback period.
