SIEMENS 7VK6111-5AB92-4YN0/EE Circuit Breaker Management Relay

Product Description

7VK6111-5AB92-4YN0/EE is a breaker management relay from Siemens SIPROTEC 4 series 7VK61 family. It is a numerical protection and control unit integrating auto-reclosure, synchro-check, breaker failure protection, pole discrepancy protection, overvoltage and undervoltage protection. This variant is equipped with text display, 4 current inputs and 4 voltage measurement inputs, abundant binary input & output terminals, flush panel mounting and configured via DIGSI 4 software. It is obsolete by OEM, with 7VK87 as its successor. It is widely used spare part for substation and MV switchgear maintenance & retrofitting projects.
