Feature → Business Impact → Application: The four-pole configuration on a Magnum PXR frame provides comprehensive phase protection, reducing cross-phase faults and improving system reliability in motor and feeder circuits used in manufacturing and processing facilities. This translates to lower downtime and smoother maintenance planning for plant operations, particularly in high-load electrical distribution cabinets. Application includes main feeders and panelboards in industrial environments where 4000 A Iu and 100 kAIC interrupt ratings are required for safe isolation during faults. Feature → Business Impact → Application: Fixed horizontal mounting simplifies cabinet layout and aligns with common DIN rail and enclosure designs, reducing install time and field wiring complexity. This improves project timelines and reduces total installed cost in new builds or retrofits. Feature → Business Impact → Application: No trip unit shipped with this unit minimizes initial procurement steps and enables customers to source a suitable trip option from the Power Xpert family as needed, enhancing flexibility for lifecycle planning. Feature → Business Impact → Application: Broad certifications (CE, UL Listed, ANSI, and more) support global compliance, easing cross-border procurement and reducing risk during audits in diverse manufacturing environments.

FAQs
The MPSC4A4HEAXXSW is a four-pole Magnum frame breaker with fixed horizontal mounting, designed to fit standard low voltage panels and cabinets. Verify enclosure width and mounting clearances (44.1 in width, 16.8 in height, 16.3 in depth) before retrofit, and confirm the panel supports four-pole devices and the required interrupt rating for your circuit. Consider using the Magnum PXR manual for installation steps and torque settings.
Key specs include a rated uninterrupted current (Iu) of 4000 A and an interrupt rating of 100 kAIC. The four-pole configuration supports full-phase protection in 3-phase systems. These values guide protection coordination, selectivity, and isolation in critical feeders, reactors, and motors, ensuring reliable fault clearance without unnecessary outages.
Yes. The four-pole Magnum frame is specifically designed for 3-phase distribution with equal protection across all poles. With a high interrupt rating and robust construction, it is well-suited for medium- to high-load industrial applications, such as metal fabrication, processing lines, and large motor drives, where dependable fault isolation is essential.
This breaker carries UL Listed and CE Marked certifications, along with ANSI and other recognized marks. It is also associated with multiple certifying bodies (KEMA, Lloyd's Register, CSA, DNV GL, ABS, etc.). This broad certification portfolio supports compliance with global electrical codes and helps streamline audits and cross-border procurement.
The unit ships without a trip unit, allowing you to select a Power Xpert Release option later if needed, which can optimize protection schemes and maintenance intervals. The high-quality Magnum frame minimizes wear in frequent switching environments, potentially reducing maintenance costs. Pairing with compatible accessories and scheduled inspections can improve uptime and extend service life in demanding industrial settings.
