Patent
CA 2695727
A circuit interrupting device configured to cause electrical discontinuity along a conductive path upon the occurrence of a predetermined condition is disclosed. The device includes a fault sensing circuit detecting the predetermined condition and generating a circuit interrupting actuation signal, and a coil and plunger assembly actuatable by the circuit interrupting actuation signal so that, upon detecting the predetermined condition, the plunger will move in a fault direction from a non- actuated to an actuated configuration a distance sufficient to cause disengagement of at least one set of contacts from each other to cause electrical discontinuity along the conductive path; and a test assembly causing the plunger to move in a test direction, from a pre-test configuration to a post-test configuration, a distance insufficient to disengage the at least one set of contacts from each other. Analogous methods of testing the circuit interrupting device are also disclosed.
