Eaton EGR-5000-2B0CB1 Generator Relay - 50/60 Hz
Part Number: EGR-5000-2B0CB1
Quick Summary
Eaton generator relay is a protection device that guards generator systems and ensures reliable start-up and shutdown in industrial plants. Engineers often struggle with nuisance trips, integration gaps, and difficult remote monitoring when protecting generators. For critical facilities, the combination of differential protection, trip coil monitoring, and Ethernet connectivity helps reduce downtime and improve fault diagnostics. While industry standards like CE, SIL, and IP ratings are commonly sought for generator protection relays, verify compliance with the specific regional requirements and manufacturer certifications. This solution aligns with generator protection, protection relays, and remote management needs, delivering value through robust sensing, flexible I/O, and scalable monitoring suitable for modern plant automation.
