Will TVSS units give an indication of a phase failure? Do they have auxiliary contacts for this?

All Surgelogic HWA series, EBA series, EMA & IMA series TVSS units will respond to a loss of one phase or two phases, and will close (or open) a set of dry contacts, but will not respond to the loss of all three phases. A phase failure relay would be needed for comprehensive phase failure protection.
