Abstract: An arc-flash sensor may provide flexibilities for supporting both surface mounting and peek-through mounting on a panel (e.g., a wall panel or an electrical panel). The arc-flash sensor includes a translucent optical lens, a fiber-optic cable, and a skirt around the back side of the optical lens. The translucent optical lens diffuses the light produced in an arc flash to enhance the detectability of light signals picked by the fiber-optic cable. The fiber-optic cable enters parallel to the panel and perpendicular to principal axis of the optical lens. The parallel fiber-optic cable configuration reduces sensor installation space occupied and potential damage to the sensor. The skirt is used to prevent false tripping caused by unexpected events on the fiber-optic cable side such as camera flashes, lightning, sunlight, or the like.

Abstract: A shorting block includes a first shorting contact having a first contact portion, a second shorting contact having a second contact portion, the first contact portion and the second contact portion may electrically couple the first shorting contact and the second shorting contact in a shorting position of the shorting block, a first activation, and a second activation contact, the first activation contact and the second activation contact may be inserted into the first shorting contact and the second shorting contact, respectively, such that the first activation contact and the second activation contact direct the first contact portion and the second contact portion away from one another to form a gap between the first contact portion and the second contact portion in an operating position of the shorting block.
