Eaton MPSC323HEAXXSW Magnum low voltage power circuit breaker - UL Listed

High current capability with 3200 A rating ensures protection for large feeders and MCCs, reducing the risk of transformer and bus faults while enabling more compact protection schemes. Business impact: improved uptime and safer fault isolation in critical power paths; Application: upstream distribution panels and motor control centers in manufacturing facilities. The 100 kA interrupting rating provides a robust fault response, limiting arc energy and downstream damage, lowering maintenance costs and downtime during short-circuit events. Application: high-energy faults in large industrial plants and data centers. This model arrives without a trip unit, offering a clean base frame that can be upgraded to Power Xpert Release trip units as needs evolve, delivering long-term cost control and flexibility. Business impact: deferred capital expenditure and scalable protection. Compatibility with fixed horizontal mounting and three-pole configuration simplifies retrofit into existing infrastructures, enabling quick field installation with standard hardware. Application: retrofit projects and new panel builds across control rooms and switchgear banks. Dimensions and weight (14.6 in L, 16.8 in H, 16.2 in W, 118 lb) support precise panel planning and stable mounting in tight installations, reducing installation time and the need for custom handling equipment. Added certifications (CE Marked, UL Listed, ANSI/CSA) provide regulatory confidence and ease cross-border procurement. Business impact: compliance assurance and smoother supplier audits. The Magnum PXR frame supports integration with Eaton’s protective-management ecosystem, giving engineers the option to scale protection with PXR trip units and Protection Manager tooling for advanced coordination and reporting.
