Wide power supply range and multi-voltage support simplify procurement and reduce inventory while enabling installation across diverse equipment. Result: faster commissioning and fewer spare parts. The 8 digital inputs, 6 digital outputs, and 1 current sensing input provide flexible local control and interlocking sequences, lowering wiring complexity and enhancing protection accuracy in feeders. With Profibus-DP over a fiber optics interface, you gain reliable, low-latency network communication, enabling remote diagnostics and tighter protection coordination across automation networks. The standard mounting method and removable terminals streamline retrofits and field wiring, cutting commissioning time and improving serviceability. A modest power draw of 10 W / 17 VA and a 5 A contact rating support steady operation in continuous-duty environments. The compact footprint (7.49 in x 8.62 in x 13.64 in) and 12.7 lb weight simplify panel layout and enclosure planning. Operating from -20°C to 60°C supports harsh industrial conditions, reinforcing uptime and reliability over the product lifecycle.

FAQs
EBR-3Z-2B0DA0-B supports standard panel mounting with removable terminals, making it suitable for retrofit into existing switchgear and new installations. It provides 8 digital inputs, 6 digital outputs, and 1 current sensing input, plus a 7.49 in L x 8.62 in H x 13.64 in W footprint and 12.7 lb weight for predictable panel allocation. The unit ships with a base relay, EBR-3000, and a Profibus-DP interface.
Power supply range covers 19-300 VDC and 40-250 VAC, with 50/60 Hz operation, enabling flexible integration across mixed generation and distribution equipment. The device consumes about 10 W (17 VA) and provides a 5 A contact rating for AC/DC signaling. These specs support reliable operation in standard industrial environments while minimizing energy impact.
Yes. The relay includes a Profibus-DP interface with fiber optics connectivity (ST connector), enabling fast, deterministic data exchange with automation controllers and SCADA. This supports remote monitoring, diagnostics, and coordinated protection schemes across distributed feeders. The 8 DI, 6 DO, and 1 current sensing input facilitate embedded control within networked protection architectures.
Designed for feeder protection in electrical protection and circuit control environments, the EBR-3Z-2B0DA0-B guards feeder integrity by detecting differential currents across bus sections. It supports standard mounting for straightforward installation in control panels and switchgear, enabling reliable fault isolation and fast restoration of service in critical manufacturing or data-center environments.
Maintenance is simplified by removable terminals and a standard mounting footprint, easing inspections and field wiring. Eaton provides a warranty under policy 25-000: one year from installation or eighteen months from shipment.
