MUMBAI, India, Nov. 14 -- Intellectual Property India has published a patent application (202517095463 A) filed by Eaton Intelligent Power Limited, Dublin, on Oct. 4, for 'mechanical advantage contact opening mechanism for circuit interrupters.'
Inventor(s) include Holp, Tyler; and Rohn, David R.
The application for the patent was published on Nov. 14, under issue no. 46/2025.
According to the abstract released by the Intellectual Property India: "An actuator for a circuit interrupter utilizes a lever to open the separable contacts of each pole assembly. The lever is coupled at a first end to a conductive plate of a Thomson coil arrangement and coupled at a second end to a movable electrode stem. The lever rotates about a pivot, and the pivot is positioned closer to the first end of the lever than the second end. The distance L1 between the first end of the lever and the pivot is shorter than the distance L2 between the pivot and the second end. When the movable electrode stem is in the closed state and the Thomson coil is activated, the conductive plate moves away from the Thomson coil at a velocity v1, and the movable electrode stem separates from the fixed electrode stem at a velocity v2 that is greater than v1 by a factor of L2/L1."
The patent application was internationally filed on Apr. 24, 2024, under International application No.PCT/IB2024/054012.
