Circuit breaker accessory cover interlock and forced safety tripping apparatus, systems, and methods
Patent number: 10418197Abstract: A circuit breaker having a housing with an accessory cover includes an accessory cover interlock assembly that trips the circuit breaker upon removal of the accessory cover. The accessory cover interlock assembly includes a plunger rotatable from an initial install position to an engaged position that moves a trip lever into a de-energize position (tripping the circuit breaker) upon removal of the accessory cover. The accessory cover interlock assembly prevents the circuit breaker from being reset while the access cover is removed. The accessory cover interlock assembly automatically resets upon re-attachment of the accessory cover to the circuit breaker housing. Methods of forced safety tripping in a circuit breaker are also provided, as are other aspects.Type: GrantFiled: July 25, 2017Date of Patent: September 17, 2019Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Jan Rojko, Jorg Sizemore, John Quentin Cowans -

Patent number: 9812268Abstract: A circuit breaker includes an accessory pocket, an accessory cover and a locking device to lock the circuit breaker such that an unauthorized switching of the circuit breaker from OFF to ON or from ON to OFF states is prevented. The locking device includes a first subassembly including a pocket housing. The first subassembly is configured to be installed in the accessory pocket. The locking device further includes a second subassembly including a cylinder lock. The second subassembly is configured to be mounted to the accessory cover. The first subassembly and the second subassembly are configured to self align upon final assembly of the circuit breaker to perform a locking function of the circuit breaker. In this way, the locking device prevents circumvention of a locking feature and selectively provides an ability to lock in an ON state of the circuit breaker.Type: GrantFiled: February 11, 2016Date of Patent: November 7, 2017Assignee: SIEMENS AKTIENGESELLSCHAFTInventor: John Quentin Cowans

Patent number: 8159318Abstract: A circuit breaker includes a trip unit and an electronic fault detection unit sharing a common trip latch for causing the circuit breaker to trip upon detection of a fault by either unit. The circuit breaker has an electromagnet for causing the circuit breaker to trip upon detection of a fault by an electronic fault detection unit. The electromagnet is oriented in the housing proximal the trip latch without any components interposed between them, and directly attracts the latch. Advantageously the electromagnet orientation does not impact operation or the range of motion of the latch or other trip unit components. Advantageously the circuit breaker of the present invention does not increase the trip latch mass, its bulk swept volume through its range of motion or require additional linkage components that potentially might increase trip cycle time. In some embodiments the electromagnet core is reciprocable.Type: GrantFiled: September 16, 2009Date of Patent: April 17, 2012Assignee: Siemens Industry, Inc.Inventors: Guang Yang, John Quentin Cowans
