High-current capability and robust frame drive reliable protection for heavy feeders in manufacturing and processing plants. This translates to fewer breaker replacements, reduced downtime during fault events, and lower total cost of ownership for critical lines. The MPSC203HEAXX2C supports precise protection coordination with the Power Xpert Release (PXr) trip units, enabling selective tripping that minimizes impact on healthy circuits and speeds fault isolation in automated lines. The three-pole design with fixed horizontal mounting simplifies retrofits in crowded panels, improving installation speed and consistency while maintaining safe clearances and wiring practices. Compliance with UL Listed, CE Marked, CSA, and other international approvals reduces procurement risk and streamlines audits across multinational sites. The combination of 2000 A power frame, 100 kA interrupt rating, and compatible protection management tools delivers measurable improvements in reliability, maintenance planning, and operational efficiency. Engineers gain confidence knowing renewal parts, compatibility with existing Eaton accessories, and documented installation guidance support long-term serviceability in evolving automation environments.
