FAQs
This three-pole unit uses a drawout vertical mounting in a double standard frame, making installation and maintenance straightforward in control panels and switchgear. Plan for adequate space in front of the panel for removal and testing, ensure compatibility with existing Magnum PXR trip units, and verify panel bus bar clearances to avoid contact during maintenance.
The breaker provides 6000 A rated uninterrupted current (Iu) and an 85 kAIC interrupt rating, enabling it to handle high fault currents without nuisance trips. With a three-pole configuration and PXR25 LSI ARMS trip unit, it supports selective tripping, improving feeder protection and minimizing collateral damage during faults.
Yes. The PXR25 LSI ARMS trip unit is designed for advanced protection coordination, enabling selective tripping across feeders. This reduces the scope of outages and improves system reliability, especially in complex distributions found in manufacturing and data center environments.
The unit carries UL Listed and CE Marked certifications, along with KEMA Certified status and CSA Certification. Additional approvals include ANSI, Lloyd's Register, ABS, and DNV GL, supporting global deployment and regulatory compliance across industries.
Plan for periodic verification of trip unit settings and mechanical operation, especially after firmware or protection-manager updates. The Power Xpert Protection Manager integration supports remote monitoring and diagnostics, enabling proactive maintenance and potentially extending service life while reducing unplanned downtime.
