A slide-in clamping device for removably connecting a first electrical terminal of a withdrawable low-voltage circuit breaker to a corresponding second electrical terminal of a respective stationary base in a withdrawable low-voltage circuit breaker unit includes at least one pair of first clamping fingers facing each other and at least partially laterally delimiting a first clamping seat for one of said first and second electrical terminals; at least one pair of second clamping fingers facing each other and at least partially laterally delimiting a second clamping seat for the other of said first and second electrical terminals; and bias elastic mechanism acting on said at least one pair of first clamping fingers and said at least one pair of second clamping fingers.

An operating handle interface assembly is for an electrical system. The electrical system includes an enclosure having an interior and an exterior, and a plurality of electrical switching apparatus disposed within the interior. Each of the electrical switching apparatus includes an operating handle. The operating handle interface assembly includes a linking assembly structured to interconnect the operating handles of a plurality of the electrical switching apparatus. An elongated shaft includes opposing first and second ends. The first end cooperates with one of the operating handles of one of the electrical switching apparatus. The second end is disposed on the exterior of the enclosure. A handle attachment is coupled to the second end of the elongated shaft on the exterior of the enclosure. The handle attachment is operable among a plurality of positions to correspondingly operate the operating handles of all of the interconnected electrical switching apparatus.

A disconnect switch including a main disconnect switch integrated with a bypass switch. The purpose of he bypass switch is to provide a parallel path for temporarily closing the disconnect switch so that the main disconnect switch can be tested (i.e., opened and closed) without interrupting the power flow through disconnect switch. The bypass switch is integrated with the main disconnect switch and supported by the same insulator structure, which avoids duplication of parts and provided for a compact unit suitable for deployment on a pole or other mounting structure outside a substation. The bypass switch also includes a frame-mounted linkage at ground voltage operated by an actuator at ground voltage, which avoids the use of hot sticks to operate the bypass stitch.
