Patent number: 10903021Abstract: A pole unit has an actuator shaft that is rotatable about a switch axis to switch the pole unit between open and closed conditions. A linkage is configured to rotate the actuator shaft in response to movement of the handle pivotally about the orthogonal axis. The linkage includes a panel configured to rotate the actuator shaft upon sliding movement of the panel. The linkage further includes links that are pivotally coupled in series between the handle and the panel to slide the panel in response to pivotal movement of the handle.Type: GrantFiled: December 26, 2019Date of Patent: January 26, 2021Assignee: Eaton Intelligent Power LimitedInventors: Romil Vaishnavi, Prashant N. Savgave

Patent number: 10818451Abstract: An electrical switching apparatus includes a first pole unit, a second pole unit, and a busbar assembly interconnecting the first pole unit with the second pole unit in series or in parallel. A first mechanism is configured to switch the first pole unit between its open and closed conditions. A second mechanism is configured to switch the second pole unit between its open and closed conditions. An actuating assembly is configured to actuate the first and second mechanisms to switch the first and second pole units from their open conditions to their closed conditions simultaneously, and to switch the first and second pole units from their closed conditions to their open conditions simultaneously.Type: GrantFiled: February 8, 2019Date of Patent: October 27, 2020Assignee: Eaton Intelligent Power LimitedInventors: Romil Vaishnavi, Warren Clift Sipe, Arthur James Jur

Patent number: 10607796Abstract: An apparatus includes a switch having alternately open and closed conditions, and a shunt trip mechanism configured to detect and respond to an electrical fault condition. The apparatus further includes an operating mechanism including a spring assembly. The operating mechanism is actuatable manually to deflect the spring assembly into a stressed condition, and is actuatable automatically in response to the shunt trip mechanism to shift the switch into the open condition upon return deflection of the spring assembly from the stressed condition. The spring assembly may include springs connected in parallel.Type: GrantFiled: October 30, 2017Date of Patent: March 31, 2020Assignee: Eaton Intelligent Power LimitedInventors: Rishabh Dixit, Richard Prohaska, Romil Vaishnavi, Somnath Devarde, Prashant Savgave

Patent number: 10483058Abstract: An apparatus includes a circuit interrupting device installed in a cabinet. The circuit interrupting device has an actuator configured for rotation about a switching axis to switch the device between ON and OFF conditions. The apparatus further includes a front access hub supported for rotation about an axis orthogonal to the switching axis. A handle is coupled to the front access hub to rotate the front access hub about the orthogonal axis. A mechanism interconnects the front access hub with the actuator to rotate the actuator in response to rotation of the front access hub.Type: GrantFiled: May 23, 2017Date of Patent: November 19, 2019Assignee: Eaton Intelligent Power LimitedInventors: Romil Vaishnavi, Chitra Dattaraya Nanaware, Somnath Janaba Devarde

Patent number: 10319544Abstract: An electrical switch assembly includes a first contact supported for movement into and out of electrical connection with a second contact. A cam assembly is configured to deflect a spring into a stressed condition, and to move the first contact into electrical connection with the second contact under a bias of the spring upon return deflection of the spring from the stressed condition. A motor has an output member. A linkage interconnects the output member with the cam assembly to deflect the spring into the stressed condition in response to movement of the output member.Type: GrantFiled: June 16, 2017Date of Patent: June 11, 2019Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Romil Vaishnavi, Douglas Ray Bender, Chitra Dattaraya Nanaware, Somnath Janaba Devarde
