FAQs

The MPSC164HEAXX2C is designed with a standard Magnum frame, four-pole configuration, and fixed horizontal mounting, ensuring straightforward integration into compatible switchgear. It supports the Magnum PXR protection scheme and LSIG trip units, enabling seamless coordination with Eaton protection devices. For retrofit projects, verify panel busbar spacing and mounting clearance to confirm fit and alignment with your current protection strategy.
Key specs include a 1600 A Iu rated continuous current and a 100 kAIC interrupt rating, four-pole configuration, and a PXR20 LSIG trip unit. These characteristics enable robust fault clearance for high-demand feeders and reliable operation under short-circuit conditions. It also aligns with common LV circuit protection standards across regional markets.
Yes. The 100 kAIC interrupt capacity minimizes arc energy during faults, protecting motor loads and feeders. The LSIG trip unit provides precise, coordinated protection to reduce unnecessary trips, which is essential for manufacturing lines and critical power circuits. This makes it well-suited for large motors, pumps, and conveyors in industrial environments.
The unit carries UL Listed, CSA Certified, CE Marked, and NEMA Compliant certifications, with additional regional marks as applicable. These certifications support regulatory acceptance in multiple regions, simplify procurement for global projects, and help ensure safety, environmental, and performance requirements are consistently met across sites.
Maintenance considerations focus on readily available renewal parts, comprehensive datasheets, and compatibility with Eaton's protection management tools like Power Xpert Protection Manager. This enables faster commissioning, centralized configuration, and predictable service intervals, reducing field visits and improving uptime. Over the product life, this translates to lower total cost of ownership and easier spares planning.
