FAQs

The MPSC4N3HEAXXSW is a three-pole, fixed horizontal mounting breaker designed for standard distribution panels. With dimensions of 16.3 in depth, 16.8 in height, and 31.1 in width and a 237 lb weight, ensure panel clearance and mechanical fit. Note it ships without a trip unit, but supports future upgrades to Magnum PXR protection units if required.
Key specs include a 100 kA short-circuit interrupting rating and a 4000 A frame (AABBCC). It is a three-pole unit intended for fixed mounting with no integrated trip unit, suitable for high-current feeders in large distribution panels.
Yes. Its high interrupt rating and fixed horizontal mounting make it well-suited for motor control centers and main feeders in large switchgear. If future protection enhancements are planned, you can upgrade to Magnum PXR trip units via Power Xpert Release.
This model carries UL Listed, ANSI, CSA, and CE certifications, along with other compliance marks. These certifications facilitate procurement, reduce regulatory risk, and support cross-border installations in North America and internationally.
Because the unit ships without a trip unit, you can time a trip-unit upgrade to match protection strategy using Magnum PXR when ready. Renewal parts and accessories are available, supporting longer equipment life and reduced downtime, with a clear upgrade path that protects existing investments.
