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.

Patent number: 11422202Abstract: A circuit interrupting device with overload current detection is provided. It comprises a hot conductor, a main contactor and a first electromagnetic device configured to remove power from an electrical circuit when overload current exceeds a predetermined % of a rated load current. It further comprises a section of conductor that generates heat and a thermal overload current detection mechanism including a temperature sensing switch having contacts. The temperature sensing switch closes the contacts when a temperature reaches a predefined temperature threshold corresponding to an overload current, in which case the temperature sensing switch electrically couples power to a second electromagnet which is disposed across the hot conductor and a connection to a neutral conductor. The energized second electromagnet generates a magnetic force capable of moving an armature that unlatches the latch releasing the spring to open the main contactor removing power from the electrical circuit.Type: GrantFiled: August 11, 2020Date of Patent: August 23, 2022Assignee: SIEMENS INDUSTRY, INC.Inventors: Hugh T.

Patent number: 7936543Abstract: A circuit tests the health of a ground-neutral transformer within a ground fault circuit interrupter. This test can include testing both the ground-to-neutral detection circuitry and the differential current detection circuitry. The test circuit provides a conductive path through the respective cores of a differential transformer and the ground-neutral transformer of the GFCI device. A closed loop induces current from the differential transformer, which creates a current imbalance through the differential transformer. In a properly working device, the circuit breaker will trip, confirming the health of the ground-neutral transformer portion of the GFCI.Type: GrantFiled: March 26, 2008Date of Patent: May 3, 2011Assignee: Siemens Industry, Inc.Inventors: Carlos Restrepo, Hugh Kinsel, Vaske Mikani, Joselito Endozo

Patent number: 7864492Abstract: In accordance with one aspect the present disclosure is directed toward a method for detecting arc faults on a power line. The method may include monitoring power signals associated with a power line and filtering the power signals to produce a high frequency signal and a low frequency signal. A mask signal may generated based on the low frequency signal, and the high frequency signal may be analyzed to extract a broadband portion of the high frequency signal. A fault counter may be incremented if the magnitude of the broadband portion is approximately greater than a first threshold level. A fault counter may be decremented if the magnitude of the broadband portion is approximately less than the first threshold level. A trip signal is provided to a switching device associated with the power line if the fault counter exceeds a predetermined fault limit.Type: GrantFiled: October 30, 2007Date of Patent: January 4, 2011Assignee: Siemens Industry, Inc.Inventors: Carlos Restrepo, Peter Staley, Amit Nayak, Vaske Mikani, Hugh Kinsel, Solomon R.
