Four-pole design provides complete phase protection and simplifies coordination in complex feeders, delivering accurate protection and reducing the likelihood of simultaneous trips. This translates to fewer unplanned outages and faster restoration, especially in mixed-load environments like manufacturing lines and process plants. The 85 kA interrupting capacity and 5000 A short-circuit withstand (NNAABBCC) establish a robust safety envelope for high-energy events, supporting selective coordination strategies that protect upstream equipment while isolating faulted sections. The PXR20 LSIAM trip unit enables precise, adjustable protection settings and communication with Power Xpert Protection Manager, aiding predictive maintenance and remote diagnostics. Drawout vertical mounting and a Magnum double standard frame simplify integration into existing racks, minimizing installation time and reducing labor costs. Compatibility with renewal parts and accessories ensures long-term reliability and easy lifecycle support. Industry-focused validation and certifications help meet rigorous compliance requirements and streamline procurement and audit processes.
