Eaton EBR-3Z-2B0DB0-A Bus differential relay - Profibus
Part Number: EBR-3Z-2B0DB0-A
Quick Summary
The Eaton Bus differential relay protects feeders by detecting differential currents across 40-250 Vac and 19-300 Vdc systems. Operators often battle uptime losses due to nuisance trips or slow fault isolation that disrupt production. Certification status varies by region; confirm CE, UL/CSA and SIL readiness with Eaton to ensure regional approvals. With Profibus-DP fiber optic communication and conformal coated circuit boards, the unit supports reliable diagnostics and installation in harsh environments. Its eight digital inputs, six outputs, and removable terminals streamline wiring and maintenance, delivering measurable uptime gains and lower lifecycle costs.

Eight digital inputs and six digital outputs enable real-time status signaling and simple interlocks, reducing wiring errors and enabling fast fault indication. This delivers faster fault isolation in critical feeder circuits and improves overall plant reliability. Application: ideal for industrial feeders with compact control schemes. Power supply range of 19-300 Vdc and 40-250 Vac with 50/60 Hz compatibility allows universal deployment across global plants, minimizing inventory and enabling single-sourcing for multi-site operations. The Profibus-DP fiber optic interface provides robust, noise-immune communication and easier remote diagnostics, cutting maintenance overhead and enabling safer asset monitoring from control rooms. Conformal coated circuit boards extend service life in humid or corrosive environments, while removable terminals simplify field wiring, panel upgrades, and retrofits without instrument-level rewiring. Compact integration with the EBR-3000 base relay and an 8/6 IO footprint supports streamlined installation, reduced panel space, and faster MTBF improvement.

FAQs
The EBR-3Z-2B0DB0-A supports a wide voltage range from 19-300 Vdc and 40-250 Vac, operates at 50/60 Hz, and integrates with an eight-input, six-output IO scheme. It is designed to work with the EBR-3000 base relay and includes a Profibus-DP fiber optic interface for reliable field communications, simplifying multi-site installations.
Begin by mounting the unit via standard mounting methods and connect the removable terminals for easy wiring. Attach the Profibus-DP fiber optic interface (ST connector) for comms, wire the eight digital inputs and six digital outputs to your control scheme, and ensure the device is powered within 19-300 Vdc or 40-250 Vac ranges. Follow Eaton’s installation guidelines for correct grounding and protection.
Expect robust protection with a 5 A contact rating (AC/DC) and a burden of 10 W / 17 VA. The device handles -20°C to 60°C operation, supports 50/60 Hz, and provides 8 DI, 6 DO for detailed signaling. It is designed to deliver rapid fault detection in feeder circuits while enabling remote monitoring via Profibus-DP.
The product listings indicate Compliances require manufacturer confirmation. For CE, UL/CSA, SIL certifications specific to your region, contact Eaton or your authorized distributor to verify current approvals and any regional labeling requirements before procurement or deployment.
By reducing nuisance trips and accelerating fault isolation, the EBR-3Z-2B0DB0-A lowers unplanned downtime and service calls. The conformal coating enhances reliability in challenging environments, while removable terminals simplify maintenance and retrofits. The warranty offers one year from installation or 18 months from shipment, whichever occurs first, helping to manage total cost of ownership.
