Patent number: 8289112Abstract: An apparatus (1) monitors a protective device (2) of a machine (4). The apparatus (1) has a switch housing (22) with a switch head (24) and an actuator (8). In the closed state of the protective device (2), the actuator interacts with the switch head (24) with that closed state being signaled. The apparatus (1) has a tumbler device (20) with a tumbler element (30) mounted movably in the apparatus (1) to lock releasably the closed state. The tumbler device (20) has a permanent magnet (34). The magnetic force fixes the tumbler element (30) in a first position when the power supply to the apparatus (1) is switched off to lock the closed state of the protective device (2), in a second position with the tumbler device (20) not locking the closed state.Type: GrantFiled: June 5, 2012Date of Patent: October 16, 2012Assignee: Euchner GmbH & Co. KGInventors: Erik Bächle, Walter Link

Patent number: 8269120Abstract: A system and method of interlocking a plurality of electrical panel switches includes an interlock assembly having an interlock. The interlock has a first position that allows connection of one of utility power and power from an alternate power supply, such as a generator, to the electrical panel and prevents connection of the other of the utility power and alternate power. The interlock has a second position that allows connection of the other of the utility power and alternate power and prevents connection of one of the utility power and alternate power to the electrical panel. The interlock also is constructed to control the positioning and sequence of operation of neutral connections between the power supplies and the electrical panel.Type: GrantFiled: July 27, 2009Date of Patent: September 18, 2012Assignee: Reliance Controls CorporationInventors: David D. Flegel, J. Mark Wilkinson

Patent number: 8247715Abstract: A circuit breaker, comprising a locking device, a secondary cover and a tripbar operatively associated with the locking device. The locking device comprises a lock assembly and a piston assembly operatively coupled with the lock assembly. A through hole for the lock assembly is provided in the secondary cover. The lock assembly has a locked position and an unlocked position, and the piston assembly has a work position and a rest position respectively corresponding to the locked and unlocked positions. The piston assembly is configured to prevent the tripbar from moving to a relatch position when it is in the work position, such that the circuit breaker cannot be turned on. The locking device is configured to be installed on the circuit breaker through the through hole.Type: GrantFiled: April 21, 2010Date of Patent: August 21, 2012Assignee: Eaton CorporationInventor: Yu Yu

Publication number: 20120186952Abstract: The present invention provides a switch that can prevent a locking member from being lost, that allows easy operations of handle locking and unlocking, and that allows more secure handle locking. A switch of the present invention includes a fixed contact point, a moving contact point capable of making contact with the fixed contact point, a handle to move the moving contact point, and a locking lever to lock the handle. The handle is equipped integrally with an overhang portion. The overhang portion is formed with a notched portion. The locking lever is equipped integrally with a projecting portion. The locking lever is pressed upwardly by a spring. When the handle is at a first position, an operation of the handle is locked by engaging the projecting portion to the notched portion. When the handle is at a second position opposite to the first position, an operation of the handle is allowed by letting the projecting portion abut on a lower surface of the overhang portion.Type: ApplicationFiled: January 11, 2012Publication date: July 26, 2012Inventors: Masaya Hatano, Hiroyuki Okamura

Patent number: 8228146Abstract: An apparatus (1) for monitoring the state of a protective device (2) of a machine (4) in particular is a safety switch for monitoring the closed state of a protective door or the like. The apparatus (1) has a switch housing (22) with a switch head (24) and an actuator (8). In the closed state of the protective device (2), the actuator interacts with the switch head (24) and, as a result, the closed state of the protective device (2) can be signaled. The apparatus (1) has a tumbler device (20) with a tumbler element (30) mounted movably in the apparatus (1) and by which the closed state of the protective device (2) can be locked releasably. The tumbler device (20) has at least one permanent magnet (34).Type: GrantFiled: April 24, 2007Date of Patent: July 24, 2012Assignee: Euchner GmbH & Co. KGInventors: Erik Bächle, Walter Link

Publication number: 20120132506Abstract: A circuit breaker is disclosed that has a neutral lock-out mechanism that prevents electrical connection between a power source and a load when a neutral rail is disconnected from the circuit breaker. The circuit breaker has a line connector, a load connector and a plug-on neutral line connector. A trip mechanism has an on position allowing electrical connection between the line connector and the load connector. The trip mechanism has a tripped position interrupting electrical connection between the line connector and the load connector in response to detection of a fault condition such as a short circuit. The trip mechanism also has an off position which is required before resetting the trip mechanism to the on position. A trip link is coupled to the trip mechanism. The trip link has a first position that prevents the trip mechanism from being reset to the on position. The trip link has a second position allowing the trip mechanism to be reset to the on position.Type: ApplicationFiled: November 30, 2010Publication date: May 31, 2012Applicant: SCHNEIDER ELECTRIC USA, INC.Inventor: Jason Potratz
