Can an 8430MPS phase failure relay be used to protect multiple motors through a common control circuit without using a shunt trip breaker?

It is possible but is not the normal arrangement. For safety reasons, a three wire control scheme should be used. The relay will reset after the phase troubles are resolved, restoring control power to the circuit.
