Eaton EBR-Z-2A1 Bus differential relay - Projection Mount
Part Number: EBR-Z-2A1
Quick Summary
Eaton Bus differential relay is designed for high-impedance feeder protection in electrical distribution panels. Engineers often face nuisance trips and slow fault isolation under dynamic fault conditions. Certification details should be confirmed with the manufacturer, with potential considerations for CE, IP ratings, and SIL depending on configuration. In practice, this solution delivers reliable feeder protection with a projection mounting advantage and compatibility with Eaton's EBR-3000 base relay, enabling faster integration into existing protection schemes while reducing panel footprint and lifecycle cost.

High-impedance protection delivers precise fault discrimination, reducing nuisance trips and improving overall system uptime, which translates to greater machine availability and lower maintenance overhead in feeder protection scenarios. The device carries a 5200 Joules energy rating, providing robust surge resilience that minimizes transient damage during fault events and supports longer equipment life. Projection panel mounting simplifies installation, reduces space requirements, and speeds commissioning in compact switchgear, a value driver for panel builders and installers working in tight enclosures. Compatibility with the EBR-3000 base relay tightens integration with Eaton protection schemes, lowering spare-part complexity and accelerating retrofits or expansions. The operating temperature range of -20°C to 60°C ensures reliable operation across typical industrial environments, while a straightforward warranty and manufacturer support add reassurance for procurement teams seeking predictable total cost of ownership. This combination of protection accuracy, durability, and installation efficiency makes the EBR-Z-2A1 well-suited for feeder protection in manufacturing plants, data centers, and utility-grade panel assemblies.
