Potential relay start capacitor cooling equipment relays.
Everyone in the field calls them potential relays in addition look at a schematic on an ac and you ll find pr potential relay.
The potential relay is normally closed and it opens when a sufficient pickup voltage is present between the 5 and 2 terminals on the relay.
