We have used the phase failure relays manufactured by Taylor for the past 30 years. Currently, use both the Taylor PD and PND phase failure relays in our current style switchboards. See the attachments for the wiring diagrams, specifications, operating instructions etc. Released for: Schneider Electric USA.
This device contrasts with an SSOLR with phase loss protection, which trips in less than 3 seconds and alerts the operator of a potential distribution system problem in advance of motor failure. Consequently, the problem does not propagate to affect other equipment on the system.

Phase failure relays are often used to control a shunt trip circuit breaker. When this is done, care must be taken to insure that the shunt trip circuit always has an adequate source available. This can be accomplished by using the diagram below. If a phase failure occurs on L2 or L3, the shunt trip coil will draw power from L1 through the control
