DEFINITION

Classification: 337/47

(under subclass 45) Subject matter including individual latching or tripping means associated with each separate phase or leg contact pairs thereof. Each individual latch or trip means may operate individually on its corresponding contact pair or may upon operation actuate a tripping bar whereby the remaining contact pairs are permitted to move to another position.

(1) Note. Latches, trips or holding means therefore for devices of this class are provided for in many subclasses herein. See SEARCH THIS CLASS, SUBCLASS below.
