FAQs

The MPSC4N3VEAXX2H is a three-pole, fixed-vertical-mount Magnum breaker designed to fit standard LV switchgear frames. Its double standard frame and compatible PXR trip unit simplify replacement in motor control centers and feeders, reducing commissioning time and wiring errors during retrofit projects.
It provides a rated uninterrupted current (Iu) of 4000 A and an interrupt rating of 100 kAIC. The unit uses the Magnum PXR trip mechanism, enabling precise protection for high-current loads in three-pole configurations with reliable fault interruption.
Yes. The MPSC4N3VEAXX2H incorporates a PXR20 LSI ARMS trip unit, which supports zone selective interlocking. This enables faster fault isolation and reduced arc energy, improving safety and minimizing downtime in complex switchgear assemblies.
The breaker carries UL Listed and CE Marked certifications, along with Lloyd's Register and other regulatory certifications (ANSI/CSA). This broad certification footprint supports global deployments and simplifies compliance across multiple markets.
The combination of high Iu capacity, 100 kAIC interrupt rating, and ZSI capability reduces unplanned outages and speeds fault isolation. Coupled with Magnum’s proven durability and comprehensive Eaton documentation, maintenance planning becomes more predictable and lifecycle costs decrease over time.
