Drawout vertical mounting enables easy access during inspections and rapid replacement in crowded panels, reducing maintenance time and labor costs while boosting uptime. In motor control centers and switchgear, the Magnum frame preserves fault protection in tight spaces and simplifies replacement without removing entire assemblies. The 85 kA short-circuit rating provides high fault tolerance, limiting equipment damage and unplanned downtime in high-energy processes and large motor drives. Three-pole protection delivers balanced phase protection for three-phase systems, improving reliability in industrial distribution networks. The option to upgrade to Power Xpert Release trip units offers future-proof protection, enabling selective coordination and enhanced fault isolation while minimizing downtime and training needs. Certified to UL, CSA, and CE with additional global certifications, this breaker meets regulatory requirements across multiple regions, reducing compliance risk and speeding project sign-off.
