FAQs

This model features drawout vertical mounting with motorized racking, enabling quicker, safer maintenance and easier replacement of the trip unit or breaker module. Ensure the rack position aligns with the cabinet design and verify clearance for robotic or manual racking equipment to prevent interference with nearby components.
The breaker uses a Power Xpert Release (PXR) with the LSIAM protection unit, delivering advanced protection, improved selectivity, and coordinated tripping across stages. This reduces nuisance trips while preserving downstream equipment, improving uptime in demanding industrial processes.
Yes. It provides a 100 kA short-circuit current rating (SCCR) and a 5000 A frame, enabling reliable interruption of high fault currents typical in large facilities. This makes it well-suited for manufacturing, process industries, and critical infrastructure where robust fault handling is essential.
The unit bears CE marking, UL listing, and NEMA compliance, along with additional certifications listed by Eaton. These approvals support international deployments and simplify regulatory qualification, especially in regions with stringent electrical safety requirements.
Integration with Power Xpert Protection Manager enables remote monitoring, firmware updates, and protection analytics, reducing on-site visits and enabling proactive maintenance. This translates to lower total cost of ownership, faster fault diagnosis, and improved asset lifecycle management.
