The Magnum MPSC603MEAXX2Q combines a three-pole, drawout vertical design with motorized racking, enabling fast, safe maintenance in crowded switchgear enclosures. The Power Xpert Release (PXR) 25 LSIAM trip unit delivers precise overcurrent protection and selective coordination, reducing the likelihood of cascading trips and improving overall system uptime. With a high 100 kA interrupting capacity and a 6000 A breaking capability (ABCABC), plus fan-cooling, the breaker handles demanding motor loads and short-circuit events with confidence, protecting both equipment and personnel. The unit’s dimensions (16.3 in depth, 16.8 in height, 31.1 in width) and weight (237 lb) reflect a robust, durable chassis compatible with Magnum framing and existing bus assemblies, ensuring straightforward replacement or retrofit. Certification breadth—UL Listed, CSA Certified, CE Marked, and additional international approvals—helps meet global compliance requirements across facilities and supply chains. In practice, this means reduced compliance risk, streamlined procurement, and lower lifecycle costs through longer service intervals and easier renewal-part access.
