High interrupting capacity and a PXR20 LSIG trip unit ensure selective protection and fast fault clearing. This combination limits arc energy, reduces downstream damage, and improves coordination with upstream breakers in complex motor feeders. In practice, you gain fewer nuisance trips during transient faults and more predictable operation in motor start-ups. Fixed vertical mounting simplifies integration into standard enclosures and reduces installation time. The four-pole frame aligns with common MCCB configurations, while fixed mounting supports clean wiring access and safer maintenance. This design minimizes field modifications and improves panel density in compact control rooms. Power Xpert Release with LSIG technology provides advanced protection and digital diagnostics, enabling selective coordination, easier testing workflows, and reliable commissioning in new builds or upgrades. Certified to UL, CE, and international standards with Lloyd’s Register and KEMA marks, this breaker supports global specification requirements and auditing. Compatibility with Power Xpert Protection Manager workflows streamlines monitoring, preventative maintenance, and long-term asset management. Long-life components and standardized parts help reduce spare-part inventories and maintenance overhead, while LSIG trip unit simplifies replacement and diagnostics, shortening downtime during servicing. Overall, the solution contributes to lower total cost of ownership while maintaining high safety margins.
