Description
The ABB REJ601BE446BB1NH appears to be a specific variant of the ABB REJ-601 feeder protection relay designed for use in medium-voltage electrical distribution systems. Here’s what I can tell you based on available information:
Function:
- Similar to the base REJ-601 model, the REJ601BE446BB1NH functions as a feeder protection relay for fault protection and monitoring within a medium-voltage power system.
- It protects feeders from various electrical faults, including overcurrents, earth faults (ground faults), and short circuits.
- It monitors electrical parameters (voltage, current) to detect these faults.
- Based on these detections, it can trip circuit breakers to isolate faulty sections and minimize equipment damage.
Finding Specific Information:
A dedicated datasheet specifically for the REJ601BE446BB1NH might be difficult to find publicly. However, there are ways to gather information about its functionalities:
- Online Marketplaces: Industrial parts distributors occasionally list the REJ601BE446BB1NH on online marketplaces [previous search results]. These listings sometimes include brief descriptions or part numbers that can be used for further research.
- Similar Models: The ABB website or library might have resources for similar REJ601 variants or feeder protection relays within the REJ product family. While the functionalities might not be identical, information on these models like the REJ601 can provide valuable insights into potential features of the REJ601BE446BB1NH.
Additional Resources:
