Description
The ABB REF543AM129AAAA appears to be a specific variant of the ABB REF543 feeder terminal, likely designed for medium-voltage electrical distribution systems. Here’s what I can gather based on available information:
Function:
- Similar to the base REF543 model, the REF543AM129AAAA functions as a feeder terminal for fault protection and monitoring within a medium-voltage power system.
- It monitors electrical parameters (voltage, current) to detect faults like overcurrents, earth faults, or short circuits.
- Based on these detections, it can trip circuit breakers to isolate faulty sections and minimize equipment damage.
Limited Public Information:
A dedicated datasheet specifically for the REF543AM129AAAA might be challenging to find publicly.
Available Resources:
-
ABB Website: The ABB website product search might not have a dedicated page for the REF543AM129AAAA, but it could potentially list the REF543 product family with a general description [ABB new.abb.com].
