The four-pole Magnum frame uses a double-standard design with drawout vertical mounting and extension options, enabling straightforward integration into legacy switchgear and MCCs. This compatibility reduces retrofit time, minimizes field wiring changes, and lowers installation risk. It’s well suited for feeders, motor circuits, and multi-circuit distributions in manufacturing and process industries. The Magnum PXR20 LSIG trip unit provides precise protection curves and a stable trip profile across loads. This improves selective coordination and reduces nuisance trips, contributing to higher line availability. When paired with Power Xpert Protection Manager, operators gain real-time visibility and easier configuration for centralized protection management. With an 85 kAIC interrupt rating and a 6000 A rated uninterrupted current (Iu), it withstands high fault currents inherent to large feeders. This translates to better equipment protection and reduced risk of cascading outages in critical facilities. Drawout vertical mounting with extensions simplifies maintenance and allows easier removal and replacement without disturbing neighboring devices. Its compatibility with legacy bus systems and modular protection layers supports phased upgrades across plants. UL Listed, CE marked, and multiple third‑party certifications reinforce compliance, reduce procurement risk, and streamline cross-border deployments.
