The MPSC324HEAXXSW is rated to carry 3200 A Iu with a 100 kAIC interrupt rating, four-pole configuration, providing robust protection for high-current feeder circuits and heavy equipment. This translates to reduced equipment damage, lower downtime, and improved overall plant reliability in heavy manufacturing lines and distribution panels. The standard frame and fixed horizontal mounting simplify installation, align with common enclosure footprints, and accelerate commissioning in new builds and retrofits. Although shipped without a trip unit, the breaker is field-upgradeable to Power Xpert Release trip units, enabling selective coordination and future-proof protection without hardware replacement. Certifications including UL Listed, CE Marked, CSA Certified, and additional international approvals support cross-border projects and regulatory compliance, reducing procurement risk. With a 160 lb weight and dimensions of 14.6 in depth, 16.8 in height, and 21.2 in width, the unit fits large enclosures while delivering long service life in demanding environments. The design also supports easy integration with Magnum PXR protection schemes and standard busbar configurations for fast, reliable upgrades.

FAQs

Yes, the MPSC324HEAXXSW ships without a trip unit but is fully compatible with Power Xpert Release trip units for Magnum PXR. It uses a standard four-pole, fixed horizontal mounting and a standard frame, making retrofits straightforward in existing panels. Verify busbar alignment and trip unit harness compatibility, and use Eaton’s product aids for proper sequencing and wiring.
Key ratings include a rated Iu of 3200 A and an interrupt rating of 100 kAIC for three-phase fault protection. This enables safe interruption of high-current faults, protecting transformers, motors, and feeders. The four-pole design ensures complete three-phase isolation, supporting reliable protection schemes in harsh industrial environments and enabling coordinated protection with other devices.
Ideal for heavy manufacturing, large panel boards, data centers, and utilities feeders where high fault currents and stringent protection are common. The rugged, standard-frame design suits large-power distribution systems, while field-upgradable trip units support evolving protection needs without hardware replacement, making it suitable for evolving plants and expanding facilities.
The MPSC324HEAXXSW carries UL Listed, CE Marked, and CSA Certified approvals, complemented by Lloyd's Register, ANSI, KEMA, ABS, and DNV GL certifications. This broad certification portfolio supports global deployments, helps meet safety and regulatory requirements across industries, and reduces approval cycles for multinational projects.
The breaker offers a clear upgrade path to Power Xpert Release trip units, enabling selective coordination and advanced protection without replacing the base hardware. This reduces downtime during modernization, lowers capex for future protection upgrades, and extends equipment life by enabling scalable protection strategies aligned with evolving automation and safety standards.
