Selling Policy 25-000 - Distribution and Control Products and Services
High impedance bus differential protection delivers selective fault detection, reducing nuisance trips and improving system reliability. This translates to shorter outage durations and lower maintenance costs in critical feeder configurations, making it ideal for main bus protection in medium- to large-sized switchgear where fault impedance can vary and fast clearance is essential. Projection panel mounting simplifies installation, reduces mounting footprint, and improves serviceability, enabling faster retrofits and less field downtime. The RJ45 MODBUS/DNP3 interface enables seamless SCADA integration and real-time alarms, supporting centralized protection control and easier regulatory reporting. A 5 A AC/DC contact rating ensures compatibility with trip and control circuits, reducing contact wear and improving safety for protection schemes. Burden of 10 W / 17 VA and energy rating of 5.2 kJ help manage thermal load in high-energy events, while operating temperature range of -20° to 60°C and a weight of 12.7 lb support practical field deployment in diverse environments.

FAQs
The EBR-3Z-2B0CA1-A uses projection panel mounting, which simplifies installation in existing enclosures and minimizes back-to-front clearance requirements. This mounting method accelerates retrofits and serviceability, reduces hardware complexity, and supports clean wiring pathways for reliable protection performance in medium to large switchgear configurations.
The relay provides a 5 A AC/DC contact rating, suitable for trip and control circuits in protection schemes. This rating supports reliable energization of alarm and trip coils without overloading the device, helping to maintain fast, accurate fault clearance while preserving switchgear integrity in demanding environments.
MODBUS/DNP3 over RJ45 enables straightforward integration with SCADA and energy management systems. It provides real-time status, alarms, and control signals, improving visibility into protection performance, enabling faster decision-making, and supporting compliant data logging and remote maintenance in industrial power networks.
Yes. Designed for busbar protection with high-impedance characteristics, this relay delivers selective fault detection important for main bus protection. Its robust mounting, communication options, and protective ratings make it well-suited for medium- to large-scale switchgear and distribution panel applications where fast, reliable fault clearance is critical.
Operate the relay within -20°C to 60°C and account for a burden of 10 W / 17 VA. The unit weighs 12.7 lb and uses projection mounting for easy replacement. Regular checks should verify mounting integrity, wiring connections, and SCADA communication health to sustain protection performance and minimize Downtime.
