Eaton MPSC164HEAXX2H Magnum PXR - 100 kAIC, UL Listed

Key electrical protections: The MPSC164HEAXX2H offers a 1600 A Iu rated uninterrupted current with a 100 kAIC interrupt rating, four poles, and a standard Magnum PXR frame. The PXR20 LSIAM trip unit provides fast, selective fault detection across feeders, enabling reliable coordination with downstream devices. In practice, this combination reduces nuisance trips during startup and load swings while preserving safety margins for motor and process protection. Installation efficiency: Fixed horizontal mounting and a standard frame simplify integration into existing switchgear and control panels. The four-pole design supports common industrial configurations, while panel footprint is predictable (14.6 in depth, 16.8 in height, 21.2 in width) and a rugged 160 lb enclosure suits harsh environments and long service life. Reliability and compliance: UL Listed, CE Marked, CSA Certified ensure regulatory acceptance across many markets, while the four-pole Magnum PXR supports safe, code-compliant protection for motors and feeders. This frame also aligns with common procurement specifications, reducing vendor ambiguity and accelerating parts stocking. Systems integration: Power Xpert Protection Manager compatibility enables remote monitoring, trip-event logging, and protection analytics. The PXR20 LSIAM unit supports scalable protection strategies for bigger plants, and the availability of application notes and datasheets aids engineers in designing selective coordination schemes. Lifecycle value: With robust fault interruption, arc energy control, and readily available technical resources, this breaker helps lower total cost of ownership by minimizing downtime and maintenance. Its compatibility with zone selective interlocking concepts in application papers demonstrates readiness for advanced protection schemes in heavy industries.
