摘要:
A circuit interrupter having an integrated variable timer circuit for alerting an end-user of an impending test of the circuit interrupter which expands the function of a basic circuit interrupter by adding visual/audible warning indicators and the capability of the circuit interrupter to test itself is described herein. The integrated variable timer circuit includes a variable resistor where the user can adjust the current flowing to a capacitor. The variable resistor enables the ability for the user to adjust the predetermined testing time. When the charge across the capacitor surpasses the voltage of a parallel, connected Zener diode, a transistor turns on a self-test subcircuit or visual/audible warning indicator. A switch across capacitor is used to discharge the capacitor and to reset the timer. A switch is included to enable a manual trip after the self test has completed.

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.
