High interrupting capacity paired with a robust double standard frame translates to dependable fault clearance and improved system availability. The 100 kA breaking capacity, along with a 5000 A service current rating, supports predictable coordination in motor control centers and switchgear, reducing downtime and energy waste. This is particularly valuable in high-demand manufacturing environments where uptime drives throughput and ROI. The PXR25 LSIGAM trip unit delivers precise, configurable protection curves, enhancing selectivity and lowering the risk of unnecessary trips during transients. For engineers, the result is easier tuning, faster fault diagnosis, and a safer work environment. The three-pole configuration with fixed horizontal mounting streamlines panel installation, minimizes wiring complexity, and supports compact rack layouts in new builds or retrofits. Global certifications and standards compliance provide confidence for cross-border projects and long-term asset integrity. Finally, the Magnum ecosystem integrates with Power Xpert Protection Manager for centralized monitoring and maintenance planning, delivering operational intelligence and reduced lifecycle costs.

FAQs

The MPSC503HEAXX2S uses a fixed horizontal mounting configuration and three-pole design, enabling straightforward replacement in Magnum panels or compatible switchgear. Verify fit by comparing the frame size (double standard frame) and mounting rails, then connect the Power Xpert Release trip unit wiring per the user manual. Confirm acceptable short-circuit current rating (up to 100 kA) and ensure proper clearance for the 16.8 in height and 31.1 in width footprint.
This breaker supports up to 100 kA interrupting capacity with a 5000 A service current and is equipped with the PXR25 LSIGAM trip unit for programmable protection curves. It is a three-pole device with fixed horizontal mounting, designed for precise protection coordination in heavy-duty applications while complying with UL, CE, and ANSI standards.
Yes. The three-pole, fixed horizontal design and high breaking capacity make it well-suited for motor control centers, switchgear assemblies, and other industrial power distribution applications that demand reliable short-circuit protection and coordinated protection schemes within highly loaded panels.
The MPSC503HEAXX2S carries UL Listed, CE Marked, ANSI/KEMA certification, plus SABA/NEMA compliance, and additional third-party certifications from Lloyd's Register, CSA, ABS, DNV GL, among others. This broad certification footprint helps satisfy regulatory and customer requirements across regional markets.
Integration with Power Xpert Protection Manager enables centralized monitoring, diagnostics, and proactive maintenance planning for Magnum breakers. This reduces unscheduled downtime, speeds fault prognosis, and supports optimized spare-part strategies, contributing to lower total cost of ownership over the asset lifecycle.
