FAQs
The EBR-3Z-2B0CA0-B uses a standard mounting method designed for common switchgear bezel configurations. For installation, verify the enclosure depth (7.49 in), height (8.62 in), and width (13.64 in) fit within the panel, connect the MODBUS/DNP3 RJ45 interface for integration with SCADA, and ensure wiring meets the 5 A AC/DC contact rating. Proper torquing and clearance around the module are essential for reliable operation.
This relay employs high-impedance bus differential protection to detect internal faults with fast, selective tripping. The 10.4 kJ energy handling supports robust fault energy absorption, reducing nuisance trips. In practice, this improves system uptime, enables precise feeder protection, and enhances coordination with adjacent protection devices in multi-bus configurations.
Yes. The relay includes MODBUS/DNP3 (RJ45) communication support, enabling integration with SCADA and HMIs. This allows real-time status, fault records, and alerts to be transmitted to your control room. When planning integration, confirm baud rate, addressing, and security settings with your SCADA vendor to ensure seamless interoperability.
Key specs include 50/60 Hz operation, 5 A contact rating (AC/DC), burden of 10 W / 17 VA, and operating temperature from -20°C to 60°C. Dimensions are 7.49 in depth, 8.62 in height, and 13.64 in width. The device is designed for standard mounting and is compatible with the EBR-Z High Impedance Module in a common bezel.
