Four-pole, drawout vertical mounting with the PXR20 LSIGAM trip unit enables precise protection and rapid replacement in heavy-duty motor control applications. This feature translates to shorter maintenance windows and reduced downtime, particularly in packaging lines and process manufacturing where uptime is critical. The unit’s interrupting capability up to 100 kA supports selective coordination, isolating faults quickly and limiting damage downstream—benefiting feeders and main buses in mixed-load environments. With a double standard frame and Magnum family compatibility, it fits standard enclosures and existing industrial switchgear footprints, accelerating retrofits and upgrades without extensive cabinet redesign. Compliance to UL Listed, CE Marked, and NEMA standards mitigates regulatory risk and streamlines cross-border deployments. Availability of renewal parts and accessories for PXR-equipped breakers reduces long-term spare parts inventory and maintenance costs. Integrating with Power Xpert Protection Manager enables proactive monitoring and fault analytics, improving asset management and uptime planning. In short, the MPSC5A4WEAXX2F combines rugged protection with installation flexibility and lifecycle cost savings for automation and power distribution projects.
