Eaton MPSC5N3VEAXX2C Magnum PXR breaker - 100 kAIC

Outstanding electrical robustness is achieved with a rated uninterrupted current (Iu) of 5000 A and an interrupt rating of 100 kAIC, enabling the breaker to reliably protect feeders and motor circuits under heavy fault conditions. This translates to reduced thermal stress on conductors and minimized downtime from arc flash events, especially in large switchgear and data-driven facilities. In practice, engineers can confidently coordinate with upstream devices to achieve selective protection in complex industrial networks. Magnum PXR with LSIG trip unit delivers fast, accurate fault detection and adjustable protection settings. The LSIG mechanism enhances selective coordination, reducing unwanted trips and preserving essential loads during faults, which is critical for process industries with variable starting currents. This model’s double-frame, three-pole design with fixed vertical mounting simplifies installation in existing panels while providing a robust footprint for future expansion. Comprehensive certifications—UL Listed, CE Marked, NEMA Compliant, CSA/KEMA/ABS/DNV GL as applicable—minimize compliance risk across global sites and support long-term serviceability. Integration with Power Xpert Protection Manager enables remote monitoring, diagnostic access, and proactive maintenance planning, improving asset uptime. In practice, installers benefit from consistent mounting practices, documented manuals, and a shared product ecosystem that reduces spare-part proliferation and training time.
