High interrupting capacity and a four-pole configuration deliver dependable protection for large feeders and high-demand motor circuits, mitigating fault cascades and enabling safer shutdowns with minimal collateral damage. This translates to reduced downtime costs and easier regulatory compliance in heavy industry environments. The PXR20 LSIGAM trip unit offers adjustable protection curves and arc-flash mitigation options, supporting tailored protection schemes and improved selective coordination across multi-feeder panels. In practice, this means faster fault isolation and clearer diagnostics during commissioning and routine testing. The drawout vertical design with motorized racking mounting streamlines maintenance, enabling safer, faster breaker replacements during outages and scheduled downtimes. Compatibility with Magnum PXR trip units and the Power Xpert Protection Manager enhances remote monitoring and preventative maintenance planning. Robust certifications and a 100 kA rating support global deployments in data centers, petrochem, and large manufacturing facilities, while the unit’s size and weight speak to its rugged enclosure integration and long-term reliability.
