Eaton EBR-3Z-2B0IB0-B Bus Diff Relay – High-Impedance
Part Number: EBR-3Z-2B0IB0-B
Quick Summary
The Eaton Bus differential relay is a high-impedance protection device designed for fast fault isolation in medium- to large-scale switchgear. In busy electrical installations, nuisance trips and miscoordination can drive outages and maintenance costs, so reliable differential protection is critical. Industry-standard certifications to verify for protection relays often include CE marking and IP-rated enclosures, with SIL assessments performed as part of system safety analyses. Its conformal coating, Modbus/DNP3 (RS485 or RJ45) communications, and standard mounting streamline integration, delivering faster commissioning and measurable improvements in protection accuracy for your bus system. This combination supports faster time-to-value for engineering teams and reduces lifecycle costs.

High-impedance bus differential protection provides precise fault detection by comparing currents across bus sections, reducing nuisance trips and improving system reliability. Business impact: higher availability and lower maintenance costs; Application: substations and industrial switchgear where fast isolation is essential. The integrated MODBUS/DNP3 communications over RS485 or RJ45 enables seamless SCADA integration, reducing commissioning time and configuration errors. Application: plant-wide protection schemes and remote monitoring. Conformal coating and a wide operating range (-20°C to 60°C) deliver robust performance in harsh environments, decreasing field service visits. Business impact: longer mean time between failures and lower retrofit costs; Application: outdoor enclosures and rugged indoor spaces. With a 5 A contact rating and a 10 W / 17 VA burden at 50/60 Hz, the unit aligns with common control power budgets, improving energy efficiency. Application: direct triggering and integration with control circuits. The standard mounting and practical enclosure footprint—7.49 in depth, 8.62 in height, 13.64 in width, 12.7 lb—simplify panel design and retrofits. Business impact: faster installs and scalable configurations;Warranty support reinforces ROI with a one-year policy from installation or 18 months from shipment.

FAQs
Install the unit using the standard mounting method in a suitable enclosure. Route current paths to the bus sections to be protected, connect communications via RS485 for Modbus or RJ45 for DNP3, and verify correct wiring of the 5 A contact circuit. Ensure the panel environment meets the -20°C to 60°C range and that the device is securely mounted to prevent vibration-induced faults.
The relay operates at 50/60 Hz with a 5 A contact rating (AC/DC). It presents a burden of 10 W / 17 VA and provides conformal coating for rugged environments. The operating temperature range is -20°C to 60°C, supporting reliable performance across typical industrial environments.
Yes. The device is designed for high-impedance bus differential protection, enabling accurate fault detection within bus sections and reducing the risk of unnecessary trips in complex 3-phase distributions.
Yes. The EBR-3Z-2B0IB0-B provides MODBUS and DNP3 communication options over RS485 or RJ45, facilitating seamless integration with SCADA, protection schemes, and remote monitoring systems.
