DEFINITION

Classification: 335/32

(under subclass 28) Subject matter wherein the timing or delay structure includes counting or integrating means whereby the time interval between the initial opening and the final reclosing operation or final opening (lockout) of the main contacts comprises a cycle of opening and reclosing operations or whereby the circuit completing contacts are normally latched in closed condition and released by a counting mechanism adapted to respond to successive fault current impulses until a predetermined number of such pulses after which the latch is released allowing the contacts to open.
