FAQs
Install in a drawout vertical configuration using the provided extensions and motorized racking kit. Verify bus bar alignment and ensure PXR25 LSIGAM trip settings are configured via the protection manager. Follow Eaton’s interlock documentation to minimize rack time and ensure safe, repeatable rack/unrack cycles during maintenance.
The PXR25 LSIGAM provides adjustable protection curves, fast trip times for short circuits, and event logging for diagnostic reviews. This enables precise coordination between upstream and downstream devices, reduces nuisance trips, and supports protection analytics within Power Xpert Protection Manager for proactive maintenance.
Yes. With its PXR trip technology and four-pole design, the breaker supports selectivity schemes across feeders and motors. This ensures that a fault on one branch doesn’t trip upstream devices unnecessarily, preserving process continuity and reducing the scope of outages in complex distribution systems.
The unit carries UL Listed, Lloyd’s Register, ANSI, CSA, and CE marks, among others. These certifications simplify regulatory approvals, support global sourcing, and provide auditable assurance for quality and safety across multinational facilities, aiding adherence to industry standards in critical applications.
Expect reduced downtime from fewer nuisance trips, faster maintenance via motorized racking, and easier lifecycle management through protection manager integration. The device’s high interrupting capacity also reduces the need for upstream upgrades, delivering long-term capital efficiency and improved asset availability in demanding manufacturing environments.
