Can you use the 8430MPS or 8430MPD phase failure relay on a ``Grounded B`` system 230V, 240V, 480V?

As long as the relay sees 3 phase to phase voltages that are equal, 120 degrees out of sequence with each other, and the correct sequence. The type of system doesn`t matter. The relay only reads voltage from phase to phase.
