Patent number: 11557443Abstract: A coupler between an activator mounted on an enclosure and an electronic protection device located within the enclosure facilitates alignment between the coupler and the electronic protection device during installation and requires no tool for installation. The coupler is positioned over an opening in the electronic protection device and oriented such that a first coupling portion is configured to engage a complementary coupling portion on the electronic protection device. The coupler may be manually mounted, engaging the complementary coupling portions on the door handle coupler and the electronic protection device without requiring a tool for installation. The coupler includes an upper sleeve configured to receive an axle, connected to the activator, that rotates independently of a lower sleeve which is mounted to the electronic protection device, facilitating orientation of the activator on the outside of the enclosure. The coupler provides for local lock-out of the electronic protection device.Type: GrantFiled: May 26, 2020Date of Patent: January 17, 2023Inventors: Thomas Strebel Marzano, Sadashiv Pimple, Dariusz Poczontek, Norbert Maschke, Andreas Weber

Patent number: 11496079Abstract: A motor starter has a housing, a contactor portion disposed within the housing, a motor protection system disposed within the housing adjacent to the contactor portion in a vertical direction, and an actuation system disposed within the housing. The contactor portion may switch between an open position and a closed position, in which, in the open position, current does not flow through the motor starter and, in the closed position, current is allowed to flow through the motor starter. The motor protection system includes a plurality of components that may move the contactor portion to the open position based on a current flow, in which the actuation system may move the contactor portion between the closed position and the open position in response to receiving an input.Type: GrantFiled: August 29, 2019Date of Patent: November 8, 2022Assignee: Rockwell Automation Technologies, Inc.Inventor: Thomas Strebel Marzano

Patent number: 11495956Abstract: A trip apparatus has a power terminal, an actuator, a rectifier coupled to the power terminal, a selector, and a processor, the actuator having a pusher member and a coil, the pusher member movable between a first position that does not actuate an actuator interface of a connected circuit breaker and a second position that actuates the actuator interface. The processor has a first input, a second input, and an output, the first input of the processor is coupled to the output of the rectifier, the second input of the processor coupled to an output of the selector, and the output of the processor coupled to the actuator. The processor determines a threshold based on a select signal received at the second input of the processor, and compares a voltage at the first input of the processor to the threshold. The processor controls the coil to selectively control the pusher member in the first or second position based on the comparison of the voltage at the first input of the processor to the threshold.Type: GrantFiled: August 24, 2021Date of Patent: November 8, 2022Assignee: Rockwell Automation Technologies, Inc.Inventors: Thomas Strebel Marzano, Walter Hunziker
