Trip circuit supervision relay CTC-1/2-K
The supervision relay CTC- 1/2-K is designed to be used for the supervsion of trip circuit and other important control and monitoring circuits. The connection is shown on scheme below.
- continuous supervision of circuit breaker tripping circuits
- detection of any kind of fault: trip coil interruption, loss of auxiliary or control power supply, poor contact in tripping circuits, etc
- drop out time delay up to 3 seconds (typical 1,4sec) to avoid spurious alarm during circuit breaker operation
- separate auxiliary power supply
- covers different auxiliary and control voltage ranges
- LED indication and auxiliary relay for remote alarm.
