The Klixon 4CR current type motor starting relay is a compact, high capacity relay, designed for universal application to splitphase and capacitor start, single-phase motors with start-winding currents up to 25 amperes.
Ratings indicated maximum pick-up and minimum drop-out current limits. Pick-up is the current through the relay coil required to close the relay contacts. Drop-out is the current through the relay coil at which the contacts open. A production relay of a given rating will have a pick-up and drop-out current within the rating limit.
