Part number
EMR-5000-2B0FB1

Quick Summary

Eaton motor relay EMR-5000-2B0FB1 protects motors and drives in industrial electrical systems. It consolidates protection, metering, and remote communication in a single, rugged package. End users often face wiring clutter, delayed fault diagnosis, and coordination gaps in legacy relays; this model reduces those pain points with fiber-optic Modbus RTU or DNP3 RTU interfaces, 50/60 Hz compatibility, and removable terminals for fast field service. Compliance specifics vary by region; confirm with Eaton for CE, UL/CSA listings, and IP-rated enclosure options. The product's scalable I/O, compatibility with the EMR-4000 base relay, and built-in zone selective interlocking deliver measurable improvements in reliability, maintenance efficiency, and total cost of ownership for motor-protection applications.

FAQs

EMR-5000-2B0FB1 is designed to work with Eaton's EMR-4000 base relay. It uses removable terminals for quick field wiring and supports projection mounting. Ensure control cabinet space accommodates its 8.7 in height, 9.72 in width, and 8.06 in depth, and verify 50/60 Hz sourcing for proper operation.
Key specs include 19-300 Vdc and 40-250 Vac operation, 50/60 Hz, analog I/O: 2 inputs and 2 outputs, digital I/O: 8 inputs and 9 outputs, and phase current options of 5A and 1A. It supports Modbus RTU or DNP3 RTU over fiber optic ST for robust field communication and remote diagnostics.
Yes. The unit features Zone Selective Interlocking (ZSI) with one interlock channel and sensing inputs covering Power, Voltage, Current, and Differential Protection. This enables selective feeder tripping and improved coordination in multi-motor drives, reducing fault energy and improving system stability.
The relay supports Modbus RTU or DNP3 RTU over Fiber Optic ST, and includes an IRIG-B URTD interface option. Fiber optics provide noise immunity, secure long-distance communication, and reliable remote diagnostics in electrically harsh or EMI-heavy environments.
Warranty follows Eaton Selling Policy 25-000: one year from installation or eighteen months from shipment, whichever comes first. Support includes access to Eaton’s specification sheets, service guidance, and optional field support through authorized partners.
