FAQs

This model features fixed horizontal mounting and a four-pole design, intended for main feeders and distribution panels. It plugs into standard LV panel architectures with Magnum PXR frame compatibility. When replacing older breakers, verify panel rating and torque requirements, ensure clearance for the 44.1 in width footprint, and plan for any necessary wiring harnesses or accessories to maintain safe, code-compliant installation.
Core specs include 5000 A Iu and 100 kAIC interrupt rating, four poles, and a double-standard Magnum PXR frame. These ratings support high-current fault interruption and protection for demanding feeders, reducing equipment damage risk. The lack of an integral trip unit means simpler protection settings today, with the option to upgrade to Power Xpert Release in the future for enhanced coordination.
Yes, it is designed for demanding industrial feeders thanks to its 5000 A Iu and 100 kAIC rating. For selective coordination, you can upgrade to Magnum PXR Power Xpert Release trip units, enabling coordinated protection with downstream devices and improved fault isolation without compromising existing hardware investments.
The device carries UL Listed, CSA Certified, and CE Marked status, along with NEMA compliance and additional certifications such as SABA, CCC, KEMA, Lloyd's Register, ANSI, ABS, and DNV GL where applicable. These approvals streamline regulatory acceptance in North America, Europe, and many international markets, supporting cross-border projects and supplier qualification processes.
Lifecycle value comes from long equipment life and renewal-part availability. The unit supports Magnum renewal parts and accessories, ensuring lifecycle cost control and easier spares planning. While no trip unit is included at purchase, upgrading later to a PXR release unit can deliver sustained protection performance, reducing maintenance interventions and improving uptime.
