FAQs
The relay uses projection mounting with removable terminals for quick wiring and service access. It supports a wide power range (19-300 Vdc or 40-250 Vac) and 50/60 Hz operation, helping it slot into both new builds and retrofits without major enclosure changes. Plan for secure fiber optic or network connections for Mbus or DNP3 communications and ensure protection logic aligns with your generator protection scheme.
EGR-5000-2B1LB1 provides 8 digital inputs, 9 digital outputs, and 2 analog inputs plus 2 analog outputs, along with 2 current sensing inputs. Sensing covers differential protection, current protection and metering, voltage protection and metering, and power protection and metering, enabling precise protection coordination and accurate energy measurements.
Ideal for generator protection in standby and prime power installations, including data centers, industrial plants, and power generation facilities. Its Mbus TCP or DNP3 TCP/UDP over LC duplex FO Enet, URTD interface, IRIG-B, and Sensitive Ground Input options support integration with SCADA, time synchronization, and advanced protection schemes in harsh environments.
The product specifies Compliances as Contact Manufacturer, so certification details can vary by region and installation. Typical projects verify CE or other regional safety certifications as required. For exact certification scope, consult Eaton and provide your installation location and standards to ensure compliance.
Warranty follows Eaton’s policy: one year from installation or 18 months from shipment, whichever occurs first. Features such as conformal coating, removable terminals, and a robust protection suite reduce maintenance frequency and downtime. Combined with scalable communications and efficient protection logic, this can lower lifecycle costs and improve asset uptime.
