FAQs

The MPSC124VEAXXSW is designed for fixed vertical mounting on a standard four-pole frame. It fits common industrial enclosures and panel assemblies, simplifying retrofits and new installations. Its fixed-mount configuration minimizes movement during operation and reduces wiring complexity, helping technicians achieve faster commissioning and more predictable maintenance timelines.
This model provides a 1200 A current rating with a 100 kA short-circuit interrupting capacity. It is a four-pole breaker with no trip unit installed, suitable for applications requiring robust basic protection with potential for future trip-unit upgrades while maintaining a compact, standardized footprint.
The specific MPSC124VEAXXSW unit ships without a trip unit. Magnum PXR trip units are available for compatible Magnum frames, providing an upgrade path for selective coordination. For new protection strategies, verify enclosure space, wiring, and control-system compatibility before retrofitting a PXR trip unit.
The device carries UL Listed and CE Marked certifications, along with additional compliance references such as ANSI, CSA, and other certs. It is designed to meet global regulatory requirements, including SABA listing and NEMA-related expectations, supporting compliance in multinational facilities and diverse project specs.
Ideal for motor control centers, feeder panels, and main distribution panels in manufacturing, data centers, and process facilities. Its high current rating and interrupting capacity make it well-suited for high-demand environments, while its fixed-vertical mounting simplifies installation and reduces integration risk in retrofit projects and new builds.
