Eaton EBR-3Z-2B0EA0-A Bus differential relay - Profibus-DP
Part Number: EBR-3Z-2B0EA0-A
Quick Summary
Eaton Bus differential relay protects feeders by differential sensing in industrial power systems. This device detects internal faults quickly, enabling selective tripping and minimizing collateral damage across the electrical network. Engineers often face nuisance trips and protection coordination challenges when integrating complex bus layouts, leading to downtime and increased maintenance. In this class, CE-like compliance expectations, SIL-based safety concepts, and rugged IP-rated housings are common to ensure reliability in harsh environments. The EBR-3Z-2B0EA0-A delivers Profibus-DP communication, robust input/output capabilities, and a standard mounting footprint, enabling scalable feeder protection with straightforward PLC integration and improved uptime. This translates to lower total cost of ownership and faster plant expansions.

Selling Policy 25-000 - Distribution and Control Products and Services
Power supply range and compatibility are designed to support diverse plant architectures, including 19-300 Vdc and 40-250 Vac inputs, so you can centralize protection without reconfiguring power rails. Business impact: reduced inventory complexity and faster commissioning across multiple panels; Application: feeder protection in mixed AC/DC environments. The relay provides eight digital inputs and six digital outputs with a 5 A contact rating and a 10 W / 17 VA burden, delivering reliable signaling and interlocking without oversizing external power cabinets. This enables precise control logic and faster fault isolation, improving plant availability in manufacturing and processing sites. Communication is via Profibus-DP (RS485 / D-SUB interface), enabling seamless PLC integration and enhanced diagnostics. Business impact: accelerated debugging and maintenance planning; Application: distributed protection schemes in large distributions. The unit supports standard mounting and removable terminals for quick installation and serviceability, reducing downtime during upgrades and replacements. These mechanical advantages translate into lower installation risk and predictable maintenance windows. Operational temperature range of -20° to 60°C ensures stable protection in demanding environments, while the compact footprint fits standard panels, reducing enclosure costs. Warranty follows Eaton’s policy, offering long-term confidence for mission-critical feeder protection.
