FAQs

The MPSC4N3MEAXX2A uses a drawout vertical mounting with motorized racking, designed for easy integration into standard panels and motor control centers. Its double-standard frame and three-pole configuration support scalable protection while minimizing panel downtime during upgrades or maintenance. This makes retrofits straightforward and aligns with Power Xpert Protection Manager workflows for centralized protection management.
Key ratings include an Iu of 4000 A and an interrupt rating of 100 kAIC, meaning the device can carry high continuous currents and interrupt substantial fault currents safely. These ratings are essential for protective coordination in heavy-duty motor loads, large drives, and distribution feeders in process industries and heavy manufacturing.
This Magnum breaker carries UL Listed, ANSI, CSA, CE Marked, KEMA Certified, and Lloyd's Register Certified statuses, among others. Such certifications support regulatory compliance across North America and Europe, reduce supplier risk, and simplify acceptance testing during site commissioning and audits.
Yes. The Magnum PXR trip unit is designed for integration with Power Xpert Protection Manager, enabling centralized protection configuration, event logging, and quick diagnostics. This compatibility supports scalable protection architectures and easier maintenance planning across multiple panels and sites.
The drawout vertical design with motorized racking minimizes manual handling and speeds replacement or testing of breakers, while the three-pole, double-standard frame fits standard installations without custom fabrication. Coupled with the PXR trip unit and compatible accessories, this reduces downtime, simplifies commissioning, and supports safer startup sequences.
