High interrupting capacity and frame rating give the MPSC203WEAXX2F the resilience to safely interrupt fault currents on large feeders. With a 2000 A frame and 100 kA short-circuit interrupting capability, this three-pole device handles motor loads and high-demand distribution without compromising upstream equipment. Its drawout vertical mounting simplifies installation and maintenance in crowded switchgear and MCCs. Featuring the PXR20 LSIGAM trip unit, it provides advanced protection logic and arc-energy reduction options. This improves selective coordination with upstream breakers and reduces arc flash energy by enabling settings that match system protection goals. Drawout mounting and standard frame size streamline retrofit and spare parts planning, speeding commissioning and reducing downtime. The unit’s UL listed, CE marked and NEMA compliant design supports regulatory acceptance across facilities, while certifications like KEMA certify performance under harsh conditions. Compatibility with Power Xpert Protection Manager enables centralized monitoring and easier troubleshooting across the protection stack. Overall, this combination delivers measurable efficiency gains, lower maintenance costs, and improved system uptime in demanding industrial environments.
