Feature → Business Impact → Application: The Magnum MPSC203HEAXX2F uses the Power Xpert Release trip unit (PXR20 LSIGAM) to provide configurable overcurrent protection, improving selectivity and reducing the risk of cascading faults in motor feeders. This translates to shorter fault clearance times and lower energy losses during faults, which is critical in process plants and high-demand manufacturing lines. Application-wise, it suits panelboards and motor control centers requiring precise coordination with upstream protection devices and easy integration into Power Xpert Protection Manager for centralized diagnostics and event logging. Feature → Business Impact → Application: With a standard frame and fixed horizontal mounting, installation is accelerated and retrofit compatibility is enhanced across existing Eaton Magnum installations, reducing commissioning time by days and cutting installation costs. Application: Ideal for retrofit projects or new builds in industrial facilities with limited space where a compact footprint and robust mounting simplify mechanical design and reduce panel depth. Feature → Business Impact → Application: The 3-pole configuration delivers balanced protection across phases, enabling consistent fault interruption and safer motor starting sequences in demanding environments like packaging lines and continuous process industries. Application: Suitable for 2000 A frame assemblies in machine rooms and control panels. Feature → Business Impact → Application: The device achieves high reliability with certifications including UL Listed, CE Marked, and NEMA compliance, supporting global regulatory adherence and minimizing third-party qualification time. Application: Used in multinational plants requiring cross-border compliance. Feature → Business Impact → Application: Availability of renewal parts and extensive Eaton documentation (spec sheets, guides, and application notes) supports long lifecycle maintenance, reducing total cost of ownership and ensuring ongoing spare-part compatibility for years. Application: Critical for OEMs and service teams managing large installed bases across multiple sites.

FAQs

Yes. The MPSC203HEAXX2F is built on the Magnum PXR platform and uses the same fixed horizontal mounting footprint in standard, 3-pole low-voltage panel assemblies. When replacing older units, verify catalog number compatibility (MPSC203HEAXX2F), confirm mounting dimensions (14.6 in x 16.8 in x 16.2 in) and ensure the trip unit (PXR20 LSIGAM) aligns with your protection strategy and Power Xpert Protection Manager integration.
Key specs include a 3-pole configuration, standard frame size, 2000 A rating, and a 100 kA short-circuit interrupt capability. The unit uses the PXR20 LSIGAM trip unit for adjustable protection curves and fast fault clearing. Dimensions are 14.6 in length, 16.8 in height, and 16.2 in width, with a weight of 118 lb, making it suitable for robust industrial panels.
This breaker excels in heavy-industry environments such as manufacturing plants, motor control centers, and process facilities where high-current feeders and reliable protection coordination are essential. It supports selective coordination strategies, integrates with Power Xpert Protection Manager for diagnostics, and accommodates large panels that demand durable, long-life protection solutions.
The MPSC203HEAXX2F is UL Listed and CE Marked, with NEMA Compliant and SABA Listed status. It also carries broader certifications (KEMA, Lloyd's Register, CSA, ANSI, DNV GL, ABS) that underpin global applicability, asset reliability, and regulatory alignment for multinational projects and cross-border installations.
Eaton provides extensive manuals, data sheets, and renewal parts for Magnum breakers, including the MPSC203HEAXX2F. Access to Power Xpert Protection Manager compatibility and a wide catalog of accessories reduces downtime and maintenance complexity. The result is lower lifecycle costs, quicker spare-part availability, and improved return on investment through higher panel uptime and safer, more predictable performance.
