| 337012000 | WITH DIVERSE ART-TYPE ACTUATOR FOR SINGLE SWITCH | 8 |
| 20130015940 | DISCONNECT SWITCH INCLUDING FUSIBLE SWITCHING DISCONNECT MODULESAANM Dunker; Jessica AnnAACI EdwardsvilleAAST ILAACO USAAGP Dunker; Jessica Ann Edwardsville IL US - A disconnect switch includes an enclosure containing a fusible switch disconnect assembly, and a switch mechanism and handle associated with the switch mechanism for opening and closing current paths in the fusible switch disconnect assembly. The fusible switch disconnect assembly may receive a plurality of retractable rectangular fuse modules having terminal blades. Switch contacts are provided in the fusible switch disconnect assembly and are positionable with rotary switch actuators, all of which may be operated via the handle and the switch mechanism. | 01-17-2013 |
| 20140176293 | MECHANICAL FLEXIBLE THERMAL TRIP UNIT FOR MINIATURE CIRCUIT BREAKERS - A flexible thermal trip actuator unit for a circuit breaker is disclosed. The circuit breaker prevents electrical connection between a power line source in the event of an over current. The circuit breaker includes a line connector, a load connector and a trip mechanism. The trip mechanism has an on position allowing electrical connection between the line connector and the load connector, a tripped position interrupting electrical connection between the line connector and the load connector in response to detection of a high current condition, and an off position which is required before resetting the trip mechanism to the on position. The actuator unit has a cold bar coupled to the trip mechanism, a compliant hinge and a parallel hot bar electrically coupled to the load connector. The cold bar deforms from a high current to cause the trip mechanism to assume the tripped position. | 06-26-2014 |
| 20140266561 | MEDIUM VOLTAGE CONTROLLABLE FUSE - An electric fuse, having a first fusible element and a disconnect section electrically connected in series to the first fusible element. The disconnect section is comprised of a first stationary contact, a second stationary contact and a movable contact movable from a first position electrically connecting the first and second stationary contacts to form a conductive path through the disconnect section to a second position electrically separating the first and second stationary contacts from each other and terminating the conductive path through the disconnect section. A retaining element holds the movable contact in the first position, the retaining element operable to release the movable contact from the first position when activated by an electrical (actuation) signal from an external source. | 09-18-2014 |
| 20140368309 | CIRCUIT PROTECTION DEVICE - A circuit protection device, including a conductor connected to first and second terminals and a spring exerting force on the conductor to move the conductor away from the first and/or second terminals when an over-voltage or over-temperature condition occurs within a charging circuit. One or more heat generating resistive elements melts material associated with one or more connection points of the conductor thereby releasing the conductor such that the spring moves the conductor to create an open circuit. | 12-18-2014 |
| 20150028990 | SAFETY SWITCH WITH OVER-CURRENT PROTECTION - A safety switch with over-current protection has a switching button pivotally mounted on a housing. A linking member is pivotally mounted on one end of the switching button, and is linked to the switching button to oscillate according to on and off states of the switching button. One end of the linking member corresponds to a conductive plate in the housing for connecting to a power loop. The conductive plate has a first electrical connection part and a second electrical connection part formed on two ends thereof. When the power loop has an over-current condition, the conductive plate is deformed by the generated heat such that the normally-closed electrode contact above the conductive plate bounces off to disconnect from the power loop for over-current protection. As fewer parts are needed, fast assembly and economical cost can be achieved upon production. | 01-29-2015 |
| 20160099117 | ACTUATION SYSTEM FOR AN ELECTRICAL SWITCHING DEVICE - An actuation system for a switch assembly having at least one switch includes a linear actuator drivable for actuating the switch, and a handle configured for selectively driving the linear actuator. The handle is operable in a first state in which the handle is coupled to the linear actuator such that turning the handle does not drive the linear actuator, and a second state in which the handle is coupled to the linear actuator such that turning the handle drives the linear actuator. | 04-07-2016 |

| 20090195346 | THERMAL AND/OR MAGNETIC OVERLOAD TRIP - A thermal and/or magnetic overload trip device for an electrical switching device having multiple poles includes a housing having a housing member configured to receive a plurality of functional elements and being at least partially closable, The overload trip device further including a conductor strap associated with each of the multiple poles, each conductor strap having an associated housing portion, and a rotatable trip shaft configured to rotate between a rest position and an actuating position so as to trip an associated switching mechanism. The overload trip device further including at least one rotatable adjusting element configured to set the at least one of the presettable thermal threshold and the presettable magnetic threshold. Further, the housing member is configured so that the functional elements is insertable therein and is couplable to the housing member. | 08-06-2009 |
| 20150348733 | OVERLOAD PROTECTION DEVICE AND THERMAL MAGNETIC ADJUSTABLE TRIP UNIT FOR A BREAKER COMPRISING THE SAME - An overload protection device, comprising: a first heating band (i.e. terminal), a second heating band, a bimetallic strip, and a litzendraht wire; the lower part of the first heating band is mechanically connected to the lower part of the bimetallic strip; and the two ends of the litzendraht wire are respectively and mechanically connected to the upper part of the second heating band and the upper part of the bimetallic strip. | 12-03-2015 |
