FAQs
For installation, plan to pair the EBR-Z-2B0 with the EBR-3000 base relay in a standard mount configuration. Ensure panel space accommodates the 7.49 in L × 8.62 in H × 6.82 in W footprint and a weight of about 7.4 lb. Account for wiring access, cooling, and clearance around the unit to maintain cooling and serviceability during commissioning.
The High Impedance Module delivers selective protection by reducing the likelihood of nuisance trips in networks with varying fault currents. This improves coordination between feeders and reduces unnecessary outages. In practice, it helps maintain fast clearance for true faults while avoiding false operations in complex fault energy environments.
Yes. The EBR-Z-2B0 is designed to work with Eaton’s EBR-3000 base relay and supports standard mounting for feeder protection applications. This compatibility enables straightforward upgrades and retrofit projects within existing Eaton protection schemes, reducing engineering time and streamlining field installation.
The data indicates ‘Compliances: Contact Manufacturer,’ so confirm exact certifications with Eaton. Typical protections in this category often involve CE marking and enclosure IP considerations; verify with Eaton for your region and installation, and license any applicable UL/CSA or SIL requirements as part of your procurement package.
The EBR-Z-2B0 supports reliable feeder protection with a robust energy rating of 10400 Joules and a wide operating temperature range (-20 to 60°C), contributing to reduced downtime and longer component life. Coupled with a one-year warranty (or 18 months from shipment) and simpler field installation with standard mounting, the solution offers predictable maintenance and favorable total cost of ownership.
