Eaton MPSC404HEAXX2Q Magnum low voltage power circuit breaker - UL Listed

PXR25 LSIAM trip unit provides precise protection and advanced arc fault minimization; Business impact is improved selective coordination, faster fault diagnosis, and easier maintenance planning. Application: protects large feeders and motor circuits with clear visibility into protection settings and event logs. The four-pole, fixed horizontal mounting design delivers robust mechanical stability and straightforward retrofit in standard switchgear, reducing installation time and commissioning risk. This results in reliable protection for complex distribution schemes and easier spare parts management for multi-site deployments. The unit’s 4000 A frame and 100 kA interrupting capacity translate into high fault tolerance, enabling safe operation of high-demand feeders and motors in demanding environments. In practice, engineers experience fewer nuisance trips and improved coordination during multi-load events, supporting uptime commitments in manufacturing and data center environments. Global certifications including UL Listed, CE Marked, and CSA Certified simplify procurement and cross-border project execution, while the PXR25 trip unit supports scalable protection strategies as systems grow. Power Xpert Protection Manager integration enables centralized monitoring and fast protection adjustments, reducing maintenance labor and MTTR. Zone-selective interlocking guidance further informs arc-energy management in high-energy installations, aligning with industry best practices for safe, resilient power protection.
