20100259347 | DETECTING AND SENSING ACTUATION IN A CIRCUIT INTERRUPTING DEVICE - A circuit interrupting device is disclosed that includes a first conductor, a second conductor, a switch between the first conductor and the second conductor wherein the switch is disposed to selectively connect and disconnect the first conductor and the second conductor, a circuit interrupter disposed to generate a circuit interrupting actuation signal, a solenoid coil and plunger assembly disposed to open the switch wherein the solenoid coil and plunger assembly is actuatable by the circuit interrupting actuation signal wherein movement of the plunger causes the switch to open, and a test assembly that is configured to enable a test of the circuit interrupter initiating at least a partial movement of the plunger in a test direction, from a pre-test configuration to a post-test configuration, without opening the switch. | 10-14-2010 |
20120068794 | RELEASE MECHANISM FOR CIRCUIT INTERRUPTING DEVICE - A release mechanism for a circuit interrupting device includes a ferromagnetic main frame through which can flow a current and a ferromagnetic movable core designed to be translated in an opening of the main frame between a first position where the circuit interrupting device remains closed and a second position where the circuit interrupting device is opened. The release mechanism is designed to use the flux generated inside the main frame by the current flowing through it to displace the movable core between its first and second positions. The release mechanism further includes at least two permanent magnets mounted on the main frame on each side of the opening and relatively oriented so as to generate a unidirectional unique magnet flux inside the main frame and the movable core, the magnet flux creating a first force on the movable core that tends to maintain it in its first position. | 03-22-2012 |
20130088310 | CIRCUIT BREAKER HAVING AN UNLOCKING MECHANISM AND METHODS OF OPERATING SAME - Embodiments provide an electronic circuit breaker. The electronic circuit breaker has a moveable contact arm having a moveable main electrical contact, and a lockout mechanism operable to contact the moveable contact arm and block motion of thereof, the lockout mechanism having a lockout latch with one or more pivot joints, a moveable stop, and an offset engagement portion, the moveable stop adapted to contact the moveable contact arm, and an unlock actuator providing an unlock force at the engagement portion causing lockout latch pivoting and release of the moveable contact arm. Also disclosed are secondary electrical contacts configured to engage each other in the ON configuration, with a leaf spring operably supporting a moveable one of the secondary contacts, the leaf spring configured to be flexed to close the secondary contacts. A method of operating the electronic circuit breaker is provided, as are other aspects. | 04-11-2013 |
20130187734 | MAGNETIC ACTUATOR FOR A CIRCUIT BREAKER ARRANGEMENT - An exemplary magnetic actuator for a circuit breaker arrangement includes a coil, a core with a groove for accommodating a section of the coil, and a movable plate configured to be attracted by the core. When a magnetic field is generated by the coil, the movable plate actuates the circuit breaker arrangement based on the attraction to the core. The magnetic actuator also includes a position locker for locking the coil in the groove. The position locker having a locking part protruding away from the core and over a section of the coil not accommodated in the groove. | 07-25-2013 |
20130234809 | CIRCUIT BREAKER HAVING AN UNLOCKING MECHANISM AND METHODS OF OPERATING SAME - Embodiments provide an electronic circuit breaker. The electronic circuit breaker has a moveable contact arm having a moveable main electrical contact, and a lockout mechanism operable to contact the moveable contact arm and block motion of thereof, the lockout mechanism having a lockout latch with one or more pivot joints pivotal about a pivot axis, a moveable stop on, and an offset engagement portion, the moveable stop adapted to contact the moveable contact arm, and an unlock actuator providing an unlock force at the engagement portion causing lockout latch pivoting about the pivot axis and release of the moveable contact arm. Also disclosed are secondary electrical contacts configured to engage each other in the ON configuration, with a leaf spring operably supporting a moveable one of the secondary contacts, the leaf spring configured to be flexed to close the secondary contacts. A method of operating the electronic circuit breaker is provided, as are other aspects. | 09-12-2013 |
20140218139 | ELECTRICAL OPERATOR FOR CIRCUIT BREAKER AND METHOD THEREOF - An electrical operator for a circuit breaker includes a carriage moving assembly and a solenoid having a reciprocating plunger. The plunger is configured to engage with the carriage moving assembly in response to a pulsating current. | 08-07-2014 |
20150015347 | DEVICE FOR DETECTING RESETTING OF A CIRCUIT BREAKER, ACTUATOR OF A SEPARATING MECHANISM OF THE CIRCUIT BREAKER CONTACTS, ELECTRIC CIRCUIT BREAKER AND USE OF AN INDUCED CURRENT TO GENERATE A RESETTING INDICATION SIGNAL - The detection device ( | 01-15-2015 |
