Four-pole construction with a double standard frame enables seamless replacement and uniform mounting in high-density panels. This translates into reduced spare-part variety and faster commissioning on new builds. Applications include distribution boards and motor-control centers where space is at a premium and protection coordination matters. High interrupt rating of 85 kAIC and an Iu of 5000 A provide robust fault protection for large feeders and downstream equipment, minimizing trips from faults and improving uptime in demanding plants. In practice, this reduces nuisance trips and enhances reliability across critical lines. PXR25 LSIAM trip unit enables precise protection with selective coordination, improving service continuity in multi-feeder environments and enabling smarter integration with Power Xpert Protection Manager for centralized monitoring. Drawout vertical mounting simplifies maintenance, testing, and replacement without full de-energization, promoting safer, faster swaps and compatibility with existing Magnum PXR installations. Certifications and cross‑compatibility with the Magnum PXR family support regulatory compliance and streamlined procurement across industries, while enabling advanced protection schemes for safer, more efficient operations.
