Publication number: 20230317394Abstract: A circuit interrupting device comprises a conductor capable of generating heat and a temperature-activated, permanent lock out trip mechanism. The mechanism includes a plunger, a compressed or stretched spring and a fusible metal to hold the plunger. The mechanism is located near the conductor that generates heat and is configured such that when the fusible metal melts when at least one heating element is energized or a holding wire fuses when energized in response to a failed self-test the plunger is released: allowing the compressed or stretched spring to convert its potential energy into kinetic energy and moving the plunger to generate a force to unlatch a latch releasing a first spring to open a contactor switch removing power from an electrical circuit. The constant force generated by the compressed or stretched spring on the plunger inhibits the circuit interrupting device from resetting.Type: ApplicationFiled: April 5, 2022Publication date: October 5, 2023Inventors: Hugh T. Kinsel, Joselito Endozo, Russell Thomas Watford, Raiden Jay Kim, Brian Timothy McCoy
