Two Phase Under Voltage Relay

[YERUK123]

Hi,

Can anyone suggest Two Phase Under Voltage relay? I am looking for a auxilary relay which can be mounted on DIN Rail and I have only Two Phase(R and Y) of VT as input.

Thanking you in advance.

If all you have is R and Y, use a single phase relay. If you have a third wire, how is it derived?

What Bill said.
You can two single phase relays and connect contacts of them in parallel or in series

Can you use a 3 phase relay and wire 2 of the relay inputs with R and 1 input with Y?

IS this really 2 phase (vs. open delta)? If so, I believe you can look into protection and controls for German based railway systems, which are 2 phase. Siemens, Alstom, ABB, etc.

What is your exact application?

Three phase voltage rely can see not connected phase as loss of phase situation

Not if you connect one of the phases twice..
