FAQs
To install the EBR-3Z-2B0DA1-A, mount the unit on a projection panel and secure removable terminals for wiring. Plan lead lengths to minimize shielding issues for Profibus-DP communications, route communications and power separately, and verify panel clearance for heat dissipation. Ensure the 8 inputs, 6 outputs, and 1 current sensing input are wired according to your feeder protection logic. After wiring, perform a functional test with a known fault to confirm correct differential protection behavior.
The relay supports 40-250 Vac and 19-300 Vdc power, with 50/60 Hz operation. It provides a 5 A AC/DC contact rating and a burden of 10 W / 17 VA. It includes 8 digital inputs, 6 digital outputs, and 1 current sensing input. Operating temperature ranges from -20°C to 60°C, and it is designed for panel-mounted protection with removable terminals for easy wiring and service.
Yes. The EBR-3Z-2B0DA1-A includes a Profibus-DP fiber optics interface (ST connector), which provides robust network communications with PLCs and SCADA systems. This enables seamless integration into industrial automation architectures, reduces communication noise susceptibility, and simplifies commissioning in networks that require fiber-based diagnostics and data exchange.
The product carries Eaton’s warranty policy of one year from the date of installation or 18 months from shipment, whichever occurs first. For service and post-sale support, refer to Eaton’s Selling Policy 25-000 and contact Eaton support or your distributor to discuss replacement, spare parts, and maintenance planning for ROI optimization.
Typical applications include feeder protection in industrial plants and OEM panels where rapid isolation of faults is critical.
