FAQs
The EBR-3000-2B0CA1 uses projection panel mounting, which simplifies retrofit into existing switchgear. Ensure adequate chassis clearance, proper RJ45 MODBUS/DNP3 terminations, and space for the 7.49 in L, 8.62 in H, 6.82 in W footprint. Plan for a 5 A signal path and account for the 10 W / 17 VA burden in panel calculations.
Yes, the device is rated for 50/60 Hz operation and features a 5 A AC/DC contact rating. This makes it compatible with standard protection circuits and control interlocks used in industrial substations and switchgear cabinets.
High-impedance differential protection minimizes false trips during external disturbances and magnetizing conditions, while still rapidly isolating actual bus faults. This improves reliability, reduces unplanned outages, and enhances coordination with feeder protections critical to substations and large industrial plants.
The relay provides MODBUS/DNP3 over RJ45, enabling seamless data exchange with SCADA and energy-management systems. This supports remote monitoring, fault event logging, and easier integration into digital plant architectures.
Protection scope centers on bus differential protection for busbars in switchgear and substations. Mounting is projection panel type, which facilitates retrofits and compact installations. For design planning, consider the 7.49 in length, 8.62 in height, and 6.82 in width, plus the 5 A contact rating and 10 W / 17 VA burden.
