FAQs

The MPSC323MEAXX2C uses a standard Magnum drawout vertical mounting with motorized racking, designed for compatibility with typical low-voltage panels and Eaton power distribution equipment. This enables quick replacement, safer rack operations, and straightforward integration into existing switchgear without custom adapters.
Key ratings include a 3200 A current rating and 100 kA short-circuit interrupting capacity. The unit uses a Power Xpert Release (PXR20 LSIG) trip unit, offering adjustable protection curves and coordinated protection with other devices for selective tripping and improved system reliability.
Yes. With three-pole configuration, drawout mounting, and high interrupting capacity, it is well-suited for heavy motor feeders and feeders in packaging and process lines. The LSIG trip units and PXR coordination help minimize nuisance trips while maintaining robust motor protection.
The unit carries UL Listed, CE Marked, and CSA Certified credentials, along with ANSI and other industry certifications. This broad certification footprint supports compliance in global markets and helps align with local safety, electrical, and performance codes.
Integration with Power Xpert Protection Manager enables remote monitoring, simplified fault diagnostics, and streamlined protection coordination. This reduces mean time to repair, lowers maintenance labor, and improves asset utilization, contributing to a lower total cost of ownership over the breaker’s lifecycle.
