Breaker close/trip circuit monitoring TCSSCBR
Identification
Function description
Breaker close/trip circuit monitoring
Functionality
The trip circuit monitoring function TCSSCBR is designed for supervision of control
circuits. A fault in a control circuit is detected by using a dedicated output contact that
contains the monitoring functionality.
The function picks up and trips when TCSSCBR detects a trip circuit failure. The trip
time characteristic for the function is of definite time (DT) type. The function trips
after a predefined operating time and resets when the fault disappears.
